Hi,
if I archive a file, like one creates by RawDisk,with zip command and I decompress it with UnArc, it creates a file without original attributes. If I decompress zip file with unzip command instead attributes of original file into zip archive are mantained... thus UnArc overwrite attributes of file(s) into zip archive(s) :(

@ShInKurO

Which version of zip? I have a Zip 2.2 (27.11.1997) lying around in C: here
and UnArc has no problems with detecting the Amiga Script bits stored by it.

@TetiSoft

Zip 2.3 (28-Nov-2005)
(28-11-2005)

@ShInKurO

Can confirm that Zip 2.3 seems to miss to store Amiga file attributes,
Zip 2.2 seems to work. Could not find something in the releasenotes
which comments on this, eventually it helps when you report the problem
to the person which has build and distributed V2.3.

@TetiSoft

In addition to this, it seems there is another problem connected to large file and with type of archive (0utTopic?):

I have proved to compress that 5gb file created with RawDisk using lha (version 2.12), and with zip (version 2.2), but the first show a problem with ram (it make ram disk full), while the second freeze machine after a few time during its process. The olny command-archive that works is bzip2 (which creates a tar.bzip2 file), but it is very slow to compress the file, and unArc is slow to decompress it and doesn't show how much is huge the possible decompressed file... after bzip2 process I prove to decompress the archive file and UnArc creates a decompressed file huges 1Gb (the dimension file showed by workbench as dimension of original file now is showed also by ASL as dimension of decompressed file) and not 5Gb (showed by ASL as dimension of original file), thus bzip2 doesn't archive huge file...

Thus the problem is: What kind of command can I use to compress file with huge dimension?

It stores temporary files in T: which is by default in RAM: which by default
cant hold 5GB. Read the LhA doc, at least older versions allowed to specify
a different temporary directory in ENVARC:LHAOPTS, or assign T: to a big
partition before trying to use LhA with big files.

IMHO its not proven yet that bzip2 was unable to compress a large file, its only
proven that UnArc is unable to decompress a large bzip2 file.
I'd try bunzip2 (or bzip2 -d ...) to find out if the packed file can be unpacked
to a 5GB file again.

I have proved now, it gives as output a file 1Gb huge :(
