I don't understand this. Can you show an example where an XPress compressed file is better in terms of portability than a ZIP file?
- zelon88 8y agoSome zip clients may write archives using invalid settings that render the file un-recoverable by other utilities. For example, check out this cheat sheet... (http://kb.winzip.com/kb/entry/313/ http://kb.winzip.com/kb/entry/313/) None of that data goes into an .xpr archive. So there's no ambiguity between different clients about how to compress or extract a file. There is only one way to decompress ANY .xpr archive; to search the file for instances of the dictIndex and replace them with the corresponding data. When you run out of matches; your file is rebuilt.
