Hi,

I am using the jar command to compress a directory. The size of the directory contents is 105 GB. The jar/zip that gets created is approximately 5.5 GB in size. But this file seems to be corrupt when verified using the unzip command.

Is there any limitation for the size of the zip file? Also, can there be any alternatives if there exists a limitation. (Splitting the zip files maybe during creation)

OS - SunOS 5.10

jar is not zip, jar is tar (sort of).

In other words, if you jar a dir, you need to use tar instead of zip to open it.

But why not use jar again to do the extraction instead?

Well the jar command hangs when I try to extract a large file. I used the verbose option to see if there is any activity going on but there wasn't any. Thats the reason i used unzip to test whether the file is valid.

I'm aware that the original ZIP file format limits the archive file to a maximum size of 4GB however I've been unable to find documentation from Sun that states the JAR file format is limited to a maximum file size of 4GB or that the JAR file format is based on the original ZIP file format and not the ZIP64 file format.

If it's a filesize limit, stream it:
