So ZIPs don't have any "global" directory thing? :o
- beagle3 7y agoThey have a non essential copy of the directory at the end for spoed; tools exist to rebuild it if it is corrupted from the entries inside the file. But it is usually very small (the only real life exception I met is the hvsc archive where the directory size is very significant - so they zip it again)
- labawi 7y agoThey don't have a global compression dictionary thing. Similar effect can be achieved with gzip --rsyncable, which IIRC resets the dictionary based on a rolling sum.
