Zip files are useful but can be problematic, follow these guidelines:
- Application can only handle individual zip files not an archive directory.
- Application can only handle compression versions 2.0, 2.1 or 4.5 (use zipinfo -v [zip file] for information. Test each file with unzip -t [zip file] to see that
- On MACOSX use the Archive utility for each file. Then run the command zip -d [zip file] "__MACOSX*" to delete the _MACOSX and the _DS Store directories in the archive.
Preferably use the gzip function to produce *.gz files.
