I've never had a problem with Poser's file compression. It's UNIX gzip, which is very robust. There is an decompression script to decompress a directory with Poser if you need to work on an uncompressed file, but I just uncheck the file compression box and re-save it under a new name (see below) if I need to hand edit a file.

You can also extract them with 7-zip, but they are stored without an extension, so you will need to add it afterward.

A caveat; if you have, say, myfile.cr2 and myfile.crz, they will be seen by Poser as the same file; saving one will delete the other. I asked about this and was told by Support that Poser does not support mixing of compressed and uncompressed files in the same directory; this is due to the compression method used...
