I am transferring a large .zip file (20 GB) from an NT server to HP-UX and Solaris servers. Originally I tried to use info-zip's unzip, but I found out pretty quickly that it does not support files over 4GB. Any suggestions on how to work around this problem? Different decompression utility? Different compression utility?

Save the zip file as a tar file?

What about gzip? (gzip -d)

Have you tried "jar". I believe, jar and zip are compatible

enc.

From Solaris 8 on up zip and unzip are built into the os. I believe they work fine on large files, but I'm not 100% sure of that part.

HP/UX I don't know very well so I don't have any info for you there.

Most time admins install Info-Zip (zip and unzip) on HPUX.
It will handle PKWARE zip compressed files.

GNU's gzip and unzip are also a good choice. HPUX 11.0 and earlier does not come with zip. Don't know about 11i.

see for gzip, gunzip download:

I tried Info-zip's unzip, but like I said, it can't handle large files > 4GB. I'll look into using jar -- another thought just occured. Maybe I can put cygwin on the NT machine and then gzip it there.

Ok, I have worked with solaris in the past. ANd have donr some diiging around and noticed that a zip and unzip program iz built in. However everytime i say zip or unzip the program balks at me...saying its not a true zip file. I downloaded the mozilla browser from the sun site and cannot get it to unzip. I have searched the forum, maybe not using the best criteria...

the exact error

cannot find zip file directory in program name

then cannot find zip file in program name.zip.ZIP, period

I have user tar and gzip in the past...but those boxes were already configured. All they did was ran forever without any problems..
