FreeArc
FreeArc is a free, modern general-purpose, open source file
archiver. This software runs on either a command line or a graphical
user interface. The main advantage of FreeArc is that it offers fast
but efficient compression combined with a good feature set.
This application includes lzma, ppmd and multimedia
compression algorithms with smart selection of
best algorithms for every file compressed based on
data analysis. It can locate repetitions (REP), remove
repetitions in texts (LZP), and pre-process executables (BCJ).
Moreover, in maximum compression mode compression, algorithms are
applied to data sequentially.
FreeArc provides the same compression ratio as
zip/bzip2/rar/7-zip (in different modes)
while being 1.5–3x faster.
Features include:
- Auto-selected LZMA/PPD/Multimedia compression
- Solid compression with smart updates (only changed solid
blocks are recompressed)
- User-definable solid block size (-s…) and file sorting
order (-ds…), including customized filename ordering (arc.groups)
- AES/Blowfish/Twofish/Serpent encryption with keyfiles
support and ability to chain multiple ciphers (-p, -hp, --keyfile,
--encryption=ALGORITHMS)
- Recovery record
- FAR and Total Commander plugins allow to
create/browse/extract archives using the file manager interface
- Ability to create SFX (self-extracted) archives and
installers
- Ability to list/extract archives directly from the internet
- Archive protection and recovery, including recovery over
Internet driven by CRCs of archive sectors (r/rr/-rr/--original=URL)
- Ability to test archive before and after any operation
(-tp/-t), including checking by recovery record and full archive test
- Moving to archive (m), joining archives (j), archive
recompression (ch), locking (k) and commenting (-z/cw)
- Select files by size, time/age and name (-sl, -sm, -ta,
-tb, -tn, -to, -n), select by/clear ARCHIVE file attribute (-ao/-ac)
- Base directory on disk / inside archive (-dp/-ap),
automatic generation of archive filenames (-ag)
- Errors and warnings are reported to stderr and reflected in
program exit code; --logfile option saves to the file all the
information displayed
- Configurable via arc.ini file and FREEARC environment
variable; alternative settings may be selected by means of -cfg/-env
options
