This is UnRAR port for MorphOS, AmigaOS and AROS based on source code 
version 5.8.5.

UnRAR license is available in license.txt file in this archive.
This port uses also code from newlib 3.1.0, utf8proc, libnix and iconv.
Newlib license is available in license_newlib.txt file in this archive.
Utf8proc license is available in license_utf8proc.txt file in this archive.
iconv license is available in license_libiconv.txt file in this archive.
libnix license is available in license_getpass.txt file in this archive.

Source code of this program is available on github:

Polish locale made by Marcin Labenski.
Italian locale made by Samir Hawamdeh.


There are no special requirements for MorphOS and AmigaOS4. It should work on
any system provided that is has relatively fresh version of operating system
(I test on MorphOS 3.12 and AmigaOS 4.1 FE Update 1).

AROS version requires i386 and ABI-v0.

Classic AmigaOS version requires a system with:
* CPU Motorola 68000 - no FPU is needed
* Kickstart 2.04 or newer
* ixemul V48 (
* 4MB RAM (unrar needs 2.6MB on its own)

Exact memory utilization depends on a size of compressed files. For instance
my test archive with one 2.0GB file in it, needs 32MB of RAM to unpack.


* based on unrar source code 5.8.5
* added support for AROS (i386), AmigaOS3 and AmigaOS2
* added support for large files (>4GiB) on MorphOS and AmigaOS4
* Italian locale added

* based on unrar source code 5.7.3
* support for MorphOS and AmigaOS4
* national language support in file names and passwords
* support for symbolic (soft) and hard links
* English and Polish locale


* support all the basic unrar commands and options, including listing,
unpacking (all or selected items), printing and testing archive files

* support national characters in archive name, names of files and directories
in the archive, passwords, comments and list files

* support restoring information about file modification date, owner and group

* support unpacking symbolic links and hard links stored in archives

* support unpacking multi-volume and SFX archives

* can read switches from configuration file s:rar.conf or RAR environment

* large files support (>4GiB) on MorphOS and AmigsOS4

* support AmigaOS localization via locale.library

copy unrar_mos to c:unrar
copy catalogs to locale:catalogs all

Note: MorphOS has its own unrar 3.90 in protected System:MorphOS/C direcory
that is used with higher priority than a file in c:unrar. And so if you want
to use the one from c: you need to call it explicitely, like this:

c:unrar l my_archive.rar

To avaid this, you can also copy unrar to c:unrar5, and then call it as unrar5:

copy unrar_mos to c:unrar5
unrar5 l my_archive.rar

copy unrar_aos4 to c:unrar
copy catalogs to locale:catalogs all

copy unrar_aros to c:unrar
copy catalogs to locale:catalogs all

AmigaOS3 and AmigaOS2.1:
copy unrar_aos to c:unrar
copy catalogs to locale:catalogs all

AmigaOS2.0 (no support for locale):
copy unrar_aos to c:unrar

Note 1: if you have Polish or Italian locale set and you don't like included
Polish/Italian translation, do not copy it to locale: and you will get
English only version.

Note 2: on AmigaOS3 and AmigaOS2.1 Polish translation uses ISO-8859-2 encoding
(not AmigaPL!).

Detailed port description

Basic functions

All the basic functions like listing (verbose, base, technical),
unpacking (w/ or w/o path, selected files or all), testing or printing
works fine. Note, that wherever a path is needed it has to be in amiga
format not POSIX i.e. //test.rar not ../../test.rar.

National characters support

RAR stores data in UTF-8 in an archive file, then reads it into Unicode
(wchar_t) and finally it uses it (print, create files, find files, ...)
in UTF-8. Unfortunately, no Amiga operating system supports UTF-8 today,
therefore in order to handle national characters in file names,
comments, etc. it needs to be converted to OS local encoding set in OS
prefs. Unrar reads what was set using environment variables:
* on MorphOS: CODEPAGE
* on AmigaOS4: Charset
* on AmigaOS3: there is no (read below)

Characters that cannot be converted, because are not present in selected
codepage, are replaced with '?'. That means that national characters are
fully supported but only for selected locale, i.e. if I have Polish
locale with ISO-8859-2 encoding and have a rar archive with Spanish
characters, they will not appear and will be replaced by '?'. That in
turns mean that some files may have the same names even if they are
different files. In that case only one will be unpacked. To deal with
this, you can use special environment variable RAR_CODEPAGE that allows
overriding codepage (for both MorphOS and AmigaOS4) without changing
system prefs. For an example above, if you set RAR_CODEPAGE, you will
still not see Spanish characters (unless you have the right font) but at
least you should get all the files unpacked.

On AmigaOS3 and AmigaOS2, since there is no buit-in variable to determine
system character encoding, you have to always use RAR_CODEPAGE.

National characters in file names

National characters in file names are handled as described above - this
* name of files, directories and links in an archive
* targets for symbolic and hard links in an archive
* archive names given to unrar command
* names in list files (if -sc option is not used)

Obviously, in order to see national characters in shell or when browsing
unpacked files in Ambient/Workbench you need to have fonts with the
right encoding installed in OS and set as system font and/or as Ambient

National characters in password

National characters are supported in passwords. A password can be given
in the following forms:
* from shell when asked
* in command invocation using -p switch
* from RAR environment variable
* from rar.conf configuration file

In each of the case above, only passwords containing national characters
of currently selected locale are supported and should be given using
locale encoding (as for file names described above). If the password is
not using current locale charset, RAR_CODEPAGE need to be used to select

-sc switch

Unrar has -sc<chr>[obj] switch described as "Specify the character set" that
is not very useful and not very well documented. From the source code I
read that <chr> can be one of:
* "a" for ANSI,
* "o" for OEM,
* "u" for Unicode and
* "f" for UTF-8.

For non-Windows systems, only "u" and "f" matter (BTW: "u" is UTF-16 not

[obj] is one of:
* 'c' for comment - does not apply unrar, used only in 'full' rar utility
* 'r' for redirect - applies to Windows only
* 'l' for file lists - applies to file list to unpack (specified after " at "),
file list to exclude (specified after -x at ) and filter file list
(specified after -n at ).

When -sc switch is not used, unrar will try to autodetect UTF-16 and
UTF-8 and when it fails it will assume local encoding. The latter will
also happen when "a" or "u" was used.

All above is standard unrar behavior - I'm only documenting it here.


Unrar supports wildcards in Windows style:
* "?" = any character
* "*" = any character sequence

Amiga style wildcards are not supported at this moment.

File modification dates

When unpacking, created files get modification date set as stored in RAR
archive. The date is set in the local time zone. As there is no special
attribute for creation and access dates in AmigaOS, these values are
always ignored.

File owner and group

When unpacking from RAR archive with option -ow, unrar will try to set
owner name and group. It will only succeed if a user with given name and
a group with given name is present in local system. Otherwise an error
will be printed. When -ow is not used, owner/group is ignored.

Symbolic links in an archive

RAR can store symbolic links and this unrar port supports that. When
unpacking, targets for Unix symbolic links will be changed into Amiga
links (Makelink function) provided that filesystem into which unpack is
done supports that (SFS does). When the filesystem does not support
symbolic links, an error will be printed and the symbolic link will be

As RAR stores symbolic link target in the form that is right on OS where
an archive was created, before making links in Amiga, the path needs to
be converted (for instance ../test.txt need to be changed to /test.txt).
This unrar port does such conversion.

Note: unrar checks if a link is safe to create and will skip links
targeting outside of unpacking directory. In order to make it create
them, you need to use -ola switch when unpacking.

Hard links in an archive

Hard links are supported in a similar way as symbolic links. Again, they
will only work if target filesystem supports hard links (SFS dos not).
Otherwise an error will be printed and hard link will be ignored. There
is no option in unrar that would allow the user to unpack hard links as
regular files or symbolic links - so if target filesystem does not
support hard links it is not possible to get them unpacked.

Reference files in an archive

RAR can pack identical files as references inside of an archive - that
reduces size of the archive file. In order to make such archive -oi
switch should be used when packing. When unpacking, duplicates are
re-created as separate files. That is fully supported in this unrar

NTFS Junction Points in an archive

NTFS Junction Points are like symbolic links, but their target is always
absolute path with a drive letter in front. In Unrar version 5.7 for
Unix-like systems (including Amiga) these kinds of links are always
skipped silently (!). While it is a different behavior from how it was
in 5.0, I decided to keep it unchanged for Amiga. So, in practice,
junction points are always skipped when unpacking.

Configuration file

Unrar has a config file in which you can store switches that will always
be used when unrar command is called. In order to do that, "switches="
should be present in the file with all the switches to add (for instance
"switches=-ad -ola"). This port of unrar looks for configuration file in

There is also "RAR" environment variable that can have switches to use
(like a value of "switches=" in configuration file). The priority of
resolving switches to use is: directly given in command, RAR environment
variable, configuration file.

Support for localization

This unrar port complies with localization rules of MorphOS and AmigaOS.
You can find cs/cd file for making additional translations on GitHub
in "locale" directory.

Large files support

On MorphOS and AmigaOS4 large files are supported in the following way:
* rar file can have size >4GiB
* a file expanded from a rar file may be bigger than 4GiB

The above is true provided that file system used for unpacking supports files
with size >4GiB.
OFS, FFS, PFS3, SFS and FAT32 do not support such files.
NTFS, exFAT and ext2/3/4 (on MorphOS) and SFS2 (on AmigaOS4) support large

Support for files >4GiB is currently not available on AROS, AmigaOS3 and

Notes about porting

This port is based directly on unrar source code version 5.8.5
(unrarsrc-5.8.5.tar.gz) from

For normalizing UTF, I used utf8proc. I did not need to port it to Amiga
- it compiles without any change:

For vfwprintf-like functions and multiple other wide characters related
functions (wc*, mb*, bt*, wmem*) from libc, that are not implemented on
Amiga at all, I ported the code I took from newlib 3.1.0:

For getpass() function missing in AROS I took the code from libnix 3.0
by Diego Casorran:

As libiconv is missing in AmigaOS3/AmigaOS2, I use one from Aminet ported by
Bruno Haible & Diego Casorran (LGPL):

MorphOS version of unrar has been compiled using gcc 4.4.5 (part of SDK 3.14).

AmigaOS4 version of unrar has been compiled using gcc 4.2.4 (part of SDK 53.20).

AROS version of unrar has been compoled using gcc 4.6.4 (part of Icaros 2.2).

AmigaOS3/AmigaOS2 version of unrar has been compiled using gcc 3.3 (part of
Cubic IDE).

All AmigaOS versions can also be created by crosscompiling using the same
compile versions as above from AmiDevCpp package.
