Uncompress (zlib) files that “S3 Backup” compressed to Amazon S3

backup

On windows I was using "s3 Backup" to backup files to amazon s3. One of the options is to compress with zlib.

As far as I can tell there is no mac version of this app. So now I need to figure out how to uncompress those files as I bring them on my mac. Anyone know a good way to uncompress files that were compressed with zlib?

The files retain the same name and extention after they had been compressed. I tried adding different extensions to the ends of the files to see if some standard compression programs would uncompress them but they did not.

I have also tried messing around command-line with the "uncompress" command. But no luck there either. Unless I can figure out a way to uncompress them I will be force to re-upload everything to amazon with compression off.

thanks in advance

Best Answer

To help figure out what these files are compressed with, you can try using the file command from the terminal. It should give you output like this:

% file archive.zip 
archive.zip: Zip archive data, at least v2.0 to extract
% file archive.tgz 
archive.gz: gzip compressed data, from Unix, last modified: Wed Aug  3 06:21:00 2005, max compression
% file srchive.bz2
archive.bz2: bzip2 compressed data, block size = 900k
