暂时用exfatprogs代码替换exfat-utils代码，等exfatprogs仓孵化后本仓下线。替换原因：本仓工具不支持修复exfat中的错误，而exfatprogs是Linux内核exfat驱动的maintainer开发的官方配套工具。

1.3.0 (2018-09-15)
* exfatfsck can now repair some errors.
* Added experimental Android support for exfat-utils [liminghao, LongPingWEI,
Pablo Mendez Hernandez, Pierre-Hugues Husson].
* Cleaned up FUSE code preparing for FUSE 3 support.
* Removed OpenBSD support as it does not handle -o option in fuse_main().
* Re-introduced FreeBSD support [Oleksii Samorukov].
* Fixed DragonFly BSD support [Tomohiro Kusumi].
* dirent->d_type in now filled on readdir() [Mark Browning].
1.2.8 (2018-02-03)
* Fixed new files or directories creation in the root directory: ensure there
are no 0x00 entries before valid ones; otherwise Windows can corrupt them.
* Fixed compilation on GNU/HURD platform.
1.2.7 (2017-06-05)
* Fixed handling of two last clusters: operations with files that occupy these
clusters could fail.
* Fixed crash when started with stdin, stdout or stderr closed.
1.2.6 (2017-01-28)
* Operations with directories (except initial listing) now make less
read/write system calls.
* Fixed handling of files with optional tail entries (0xe0-0xff): videoclip
files created by Sony cameras were missing.
* Write operations now correctly return ENOSPC (instead of EIO) when there is
no free disk space left.
* Fixed max file name length: it's 255 16-bit code units (not 256).
1.2.5 (2016-12-05)
* Added an option for dumpexfat to show file fragments [Daniel Drake].
* Fixed crash when directory starts with an invalid cluster.
* Daylight saving time in now properly reflected in file timestamps.
1.2.4 (2016-06-03)
* Fixed wrong files names hashes when upper case table is compressed.
* Man pages are now installed by default.
* Commas and backslashes in device names are now escaped.
1.2.3 (2015-12-19)
* Fixed clusters loss when file renaming replaces target.
1.2.2 (2015-11-09)
* Improved reliability in case of a sudden unplug: FS will be in a clean state
after closing all files and performing sync(1).
* Fixed compilation on Debian GNU/kFreeBSD and GNU/Hurd platforms.
* Updated mount.exfat-fuse man page.
1.2.1 (2015-09-24)
* Fixed compatibility with Zalman VE-200: now newly created directories do not
have archive bit set.
* Fixed heap corruption: malformed FS can use invalid sector or cluster size.
* Fixed hang on mount: malformed FS can have cyclic references in the clusters
map.
1.2.0 (2015-08-26)
* Switched from SCons to autotools.
* Added musl libc support [Brendan Heading].
* Worked around "FS is larger than device" error for memory cards formatted by
Panasonic Lumix cameras.
* Worked around "unknown entry type 0xe1" error for memory cards formatted by
Sony cameras.
1.1.1 (2014-11-15)
* Fixed mkfs crash on some sectors-per-cluster (-s option) values.
1.1.0 (2014-07-08)
* Relicensed the project from GPLv3+ to GPLv2+.
* OpenBSD support [Helg Bredow].
* Improved I/O errors handling.
* Implemented fsync() and fsyncdir().
* Fixed crash on Mac OS X 10.5 caused by non-standard use of realpath(). Also
fixed TrueCrypt disks unmounting.
* Avoid extra erase on writes to the end of a file. This should improve linear
write speed.
* Allow arbitrary changing of lower 9 bits of mode. Allow owner/group changing
to the same owner/group. This fixes rsync.
* Fixed buffers overflows when handling lengthy file names.
* Fixed "real size does not equal to size" error on volumes with pagefile.sys.
* Fixed negative IUsed in "df -i" output.
1.0.1 (2013-02-02)
* Fixed unexpected removal of a directory if it is moved into itself.
* Fixed "Operation not permitted" error on reading an empty file.
1.0.0 (2013-01-19)
* Fixed crash when renaming a file within a single directory and a new name
differs only in case.
* Fixed clusters allocation: a cluster beyond valid clusters range could be
allocated.
* Fixed crash when a volume is unmounted while some files are open.
* SConscript now respects AR and RANLIB environment variables.
* Improved error handling.
Linux:
* Enabled big_writes. This improves write speed (larger block size means less
switches between kernel- and user-space).
* Do BLKROGET ioctl to make sure the device is not read-only: after
"blockdev --setro" kernel still allows to open the device in read-write mode
but fails writes.
OS X:
* Fixed OS X 10.8 support.
* Switched to 64-bit inode numbers (now Mac OS X 10.5 or later is required).
* Switched from unmaintained MacFUSE to OSXFUSE (http://osxfuse.github.com).
* Fixed device size detection. Now mkfs works.
* Workarounded some utilities failures due to missing chmod() support.
* Disabled (senseless) permission checks made by FUSE.
0.9.8 (2012-08-09)
* The mkfs utility can now create huge file systems (up to several exabytes).
* Fixed handling of characters beyond Basic Multilingual Plane.
* Echo messages to syslog only if stderr is not connected to a terminal.
0.9.7 (2012-03-08)
* Out-of-the-box FreeBSD support (via ublio library).
* Fixed "missing EOD entry" error (could happen while reading directory that
consists of several clusters).
* Fixed interpretation of minutes field in files timestamps (minutes could be
displayed incorrectly).
* Fixed mtime seconds field initialization for newly created file (mtime could
be 1 sec less than creation time).
* SConscript now respects CC, CCFLAGS and LDFLAGS environment variables.
0.9.6 (2012-01-14)
* Fixed write performance regression introduced in 0.9.4.
* Mount in read-only mode if the device is write-protected.
* Set ctime to mtime to ensure we don't break programs that rely on ctime
(e.g. rsync considered that all files are outdated) [Eldad Zack].
* Indicate that FS in not clean when it was not cleanly unmounted.
* Utilities are now compatible with GNU/Hurd.
* Fixed several memory leaks that could occur on error handling paths.
* Improved handling of corrupted file systems.
0.9.5 (2011-05-15)
* Fixed erasing of the root directory cluster when creating a new FS with
mkexfatfs. This bug could cause mkexfatfs to produce invalid FS.
* Utilities are not linked with libfuse anymore.
* Ensure that the path being opened is either a device or a regular file.
0.9.4 (2011-03-05)
* Introduced exfat-utils: dumpexfat, exfatfsck, mkexfatfs, exfatlabel.
* Fixed "Invalid argument" error while mounting a volume from a disk with sector size greater than 512 bytes.
* Wait for all data to be flushed to disk on unmount.
* Kernel cache is no longer flushed on open. This can slightly improve read performance by avoiding extra read requests from kernel to user-space.
* Allow to unmount volumes as user (fusermount -u) if they were mounted from the very same user [Tino Lange].
* Errors and warnings are now duplicated to syslog.
0.9.3 (2010-09-25)
* Directories now can shrink.
* Improved timestamps resolution from 2 sec to 1 sec.
* Fixed timestamps displaying under Mac OS X when compiled for i386 or ppc.
* Fixed FS size displaying for non-GNU systems.
0.9.2 (2010-07-24)
* Fixed a bug which could cause the whole directory to become unreadable after renaming a file in it.
* Support for Solaris and various *BSD [Albert Lee].
* Improved error handling on corrupted volumes.
* Improved allowed file name characters filter.
* Added man page.
0.9.1 (2010-06-12)
* Implemented automounting (util-linux-ng 2.18 or later is required).
* Fixed mounting when cluster bitmap is larger than expected.
* Fixed crash on statfs() when root directory contains error.

About
-----
This project aims to provide a full-featured [exFAT][1] file system implementation for Unix-like systems. It consists of a [FUSE][2] module (fuse-exfat) and a set of utilities (exfat-utils).
## exfatprogs
As new exfat filesystem is merged into linux-5.7 kernel, exfatprogs is
created as an official userspace utilities that contain all of the standard
utilities for creating and fixing and debugging exfat filesystem in linux
system. The goal of exfatprogs is to provide high performance and quality
at the level of exfat utilities in windows. And this software is licensed
under the GNU General Public License Version 2.
Supported operating systems:
## Building exfatprogs
Install prerequisite packages:
```
For Ubuntu:
sudo apt-get install autoconf libtool pkg-config
* GNU/Linux
* Mac OS X 10.5 or later
* FreeBSD
For Fedora, RHEL:
sudo yum install autoconf automake libtool
```
Most GNU/Linux distributions already have fuse-exfat and exfat-utils in their repositories, so you can just install and use them. The next chapter describes how to compile them from source.
Compiling
---------
To build this project on GNU/Linux you need to install the following packages:
* [git][4]
* [autoconf][5]
* [automake][6]
* [pkg-config][7]
* fuse-devel (or libfuse-dev)
* [gcc][8]
* [make][9]
On Mac OS X:
* autoconf
* automake
* pkg-config
* [OSXFUSE][10]
* [Xcode][11] (legacy versions include autotools but their versions are too old)
On OpenBSD:
* git
* autoconf (set AUTOCONF_VERSION environment variable)
* automake (set AUTOMAKE_VERSION environment variable)
Get the source code, change directory and compile:
git clone https://github.com/relan/exfat.git
cd exfat
autoreconf --install
Build steps:
```
cd into the exfatprogs directory:
./autogen.sh
./configure
make
Then install driver and utilities (from root):
make install
```
You can remove them using this command (from root):
## Using exfatprogs
```
- mkfs.exfat:
Build a exfat filesystem on a device or partition(e.g. /dev/hda1, dev/sda1).
make uninstall
Usage example:
1. No option(default) : cluster size adjustment as per device size, quick format.
mkfs.exfat /dev/sda1
2. To change cluster size(KB or MB or Byte) user want
mkfs.exfat -c 1048576 /dev/sda1
mkfs.exfat -c 1024K /dev/sda1
mkfs.exfat -c 1M /dev/sda1
3. For full format(zero out)
mkfs.exfat -f /dev/sda1
4. For set volume label, use -l option with string user want.
mkfs.exfat -L "my usb" /dev/sda1
5. To change boundary alignment(KB or MB or Byte) user want
mkfs.exfat -b 16777216 /dev/sda1
mkfs.exfat -b 16384K /dev/sda1
mkfs.exfat -b 16M /dev/sda1
Mounting
--------
- fsck.exfat:
Check the consistency of your exfat filesystem and optionally repair a corrupted device formatted by exfat.
Modern GNU/Linux distributions (with [util-linux][12] 2.18 or later) will mount exFAT volumes automatically. Anyway, you can mount manually (from root):
Usage example:
1. check the consistency.
fsck.exfat /dev/sda1
2. repair and fix.(preparing)
mount.exfat-fuse /dev/spec /mnt/exfat
- tune.exfat:
Adjust tunable filesystem parameters on an exFAT filesystem
where /dev/spec is the [device file][13], /mnt/exfat is a mountpoint.
Usage example:
1. print current volume label.
tune.exfat -l /dev/sda1
2. set new volume label.
tune.exfat -L "new label" /dev/sda1
3. print current volume serial.
tune.exfat -i /dev/sda1
4. set new volume serial.
tune.exfat -I 0x12345678 /dev/sda1
Feedback
--------
- exfatlabel:
Get or Set volume label or serial
If you have any questions, issues, suggestions, bug reports, etc. please create an [issue][3]. Pull requests are also welcome!
Usage example:
1. get current volume label.
exfatlabel /dev/sda1
2. set new volume label.
exfatlabel /dev/sda1 "new label"
3. get current volume serial.
exfatlabel -i /dev/sda1
4. set new volume serial.
exfatlabel -i /dev/sda1 0x12345678

```
## Benchmarks
Some fsck implementations were tested and compared for Samsung 64GB Pro
microSDXC UHS-I Class 10 which was filled up to 35GB with 9948 directories
and 16506 files by fsstress.
The difference in the execution time for each testing is very small.
| Implementation | version | execution time (seconds) |
|----------------------|-----------------|--------------------------|
| **exfatprogs fsck** | 1.0.4 | 11.561 |
| Windows fsck | Windows 10 1809 | 11.449 |
| [exfat-fuse fsck] | 1.3.0 | 68.977 |

.SH DESCRIPTION
.B exfatfsck
checks an exFAT file system for errors. It can repair some of them.
.SH COMMAND LINE OPTIONS
Command line options available:
.TP
.BI \-a
Automatically repair the file system. No user intervention required.
.TP
.BI \-n
No-operation mode: non-interactively check for errors, but don't write
anything to the file system.
.TP
.BI \-p
Same as \fB\-a\fR for compatibility with other *fsck.
.TP
.BI \-V
Print version and copyright.
.TP
.BI \-y
Same as \fB\-a\fR for compatibility with other *fsck.
.SH EXIT CODES
Zero is returned if errors were not found. Any other code means an error.

.BI umask= value
Set the umask (the bitmask of the permissions that are
.B not
present, in octal).
The default is 0.
.TP
.BI dmask= value
Set the umask for directories only.
.TP
.BI fmask= value
Set the umask for files only.
.TP
.BI uid= n
Set the owner for all files and directories.
The default is the owner of the current process.
.TP
.BI gid= n
Set the group for all files and directories.
The default is the group of the current process.
.TP
.BI ro
Mount the file system in read only mode.
.TP
.BI noatime
Do not update access time when file is read.
.SH EXIT CODES
Zero is returned on successful mount. Any other code means an error.
.SH BUGS
exFAT is a case-insensitive file system. Some things can behave unexpectedly,
e.g. directory renaming that changes only case of some characters:
.B \t$ mv FOO Foo
.br
.B \tmv: cannot move \(cqFOO\(cq to a subdirectory of itself, \(cqFoo/FOO\(cq
This happens because
.B mv
finds that destination exists (for case-insensitive file
systems
.B FOO
and
.B Foo
are the same thing) and adds source basename to the destination. The file
system gets
.B rename(\(dqFOO\(dq,\ \(dqFoo/FOO\(dq)
syscall and returns an error.

.TH EXFATLABEL 8 "September 2017"
.SH NAME
.B exfatlabel
\- get or set an exFAT file system label
.SH SYNOPSIS
.B exfatlabel
[
.B \-V
]
.I device
[
.I label
]
.SH DESCRIPTION
.B exfatlabel
reads or changes an exFAT file system label (volume name).
If
.I label
argument is present,
.B exfatlabel
sets the new volume name. Empty label ('') removes volume name. Label can be
up to 15 characters. This limit is shorter if characters beyond Unicode BMP
are used because internally label is stored in UTF-16.
If
.I label
argument is omitted,
.B exfatlabel
just prints current volume name.
.SH COMMAND LINE OPTIONS
Command line options available:
.TP
.BI \-V
Print version and copyright.
.SH EXIT CODES
Zero is returned on success. Any other code means an error.

.TP
.B \-\-pack\-bitmap
Attempts to relocate the exFAT allocation bitmap so that it ends at the
alignment boundary immediately following the FAT rather than beginning at that
boundary.
This strictly violates the SD card specification but may improve performance
and endurance on SD cards and other flash media not designed for use with exFAT
by allowing file-system metadata updates to touch fewer flash allocation units.
Furthermore, many SD cards and other flash devices specially optimize the
allocation unit where the FAT resides so as to support tiny writes with reduced
write amplification but expect only larger writes in subsequent allocation
units \[em] where the exFAT bitmap would be placed by default.
Specifying \fB\-\-pack\-bitmap\fR attempts to avoid the potential problems
associated with issuing many small writes to the bitmap by making it share an
allocation unit with the FAT.
If there is insufficient space for the bitmap there, then this option will have
no effect, and the bitmap will be aligned at the boundary as by default.

.TH MKEXFATFS 8 "January 2014"
.SH NAME
.B mkexfatfs
\- create an exFAT file system
.SH SYNOPSIS
.B mkexfatfs
[
.B \-i
.I volume-id
]
[
.B \-n
.I volume-name
]
[
.B \-p
.I partition-first-sector
]
[
.B \-s
.I sectors-per-cluster
]
[
.B \-V
]
.I device
.SH DESCRIPTION
.B mkexfatfs
creates an exFAT file system on a block device.
.I device
is a special file corresponding to the partition on the device. Note that if
this is an MBR partition then the file system type should be set to 0x07
(NTFS/exFAT) otherwise other operating systems may refuse to mount the
file system.
.SH OPTIONS
Command line options available:
.TP
.BI \-i " volume-id"
A 32-bit hexadecimal number. By default a value based on current time is set.
.TP
.BI \-n " volume-name"
Volume name (label), up to 15 characters. By default no label is set.
.TP
.BI \-p " partition-first-sector"
First sector of the partition starting from the beginning of the whole disk.
exFAT super block has a field for this value but in fact it's optional and
does not affect anything. Default is 0.
.TP
.BI \-s " sectors-per-cluster"
Number of physical sectors per cluster (cluster is an allocation unit in
exFAT). Must be a power of 2, i.e. 1, 2, 4, 8, etc. Cluster size can not
exceed 32 MB. Default cluster sizes are:
4 KB if volume size is less than 256 MB,
32 KB if volume size is from 256 MB to 32 GB,
128 KB if volume size is 32 GB or larger.
.TP
.BI \-V
Print version and copyright.
.SH EXIT CODES
Zero is returned on successful creation. Any other code means an error.
