"is the only compression type" ? quoting from the ZIP specification:
compression method: (2 bytes)
(see accompanying documentation for algorithm
descriptions)
0 - The file is stored (no compression)
1 - The file is Shrunk
2 - The file is Reduced with compression factor 1
3 - The file is Reduced with compression factor 2
4 - The file is Reduced with compression factor 3
5 - The file is Reduced with compression factor 4
6 - The file is Imploded
7 - Reserved for Tokenizing compression algorithm
8 - The file is Deflated
9 - Enhanced Deflating using Deflate64(tm)
10 - PKWARE Data Compression Library Imploding
11 - Reserved by PKWARE
12 - File is compressed using BZIP2 algorithm
( http://www.pkware.com/company/standards/appnote/appnote.txt )
the current zipfile version only supports 0 and 8, but that doesn't mean that
future versions won't support other ZIP compressions.
