0 merges only exactly equal vertices. A small value also closes hairline cracks left by CAD exporters.
Geometry only — texture coordinates,
materials and vertex colours are not carried through. Decimating a
UV-mapped mesh correctly is a much harder problem, and mangling your
UVs quietly would be worse than leaving them alone.

ZIP and 7z. 7z encrypts the file list too.
What actually shrinks ZIP files
7z with LZMA2 is usually substantially smaller than ZIP on the same files.
The benchmark compresses your actual data with eleven algorithm and level combinations and shows the size and time for each.
Password protection is available for both ZIP and 7z; 7z also encrypts the list of file names.
