The size of the archive doesn't matter, it's the number of members. And I wouldn't call it caching either. The members are stored in order to have a table of contents and to allow random access. Also, the members list is required for resolving hard links within the archive. It cannot be dropped without side-effects. -- Lars Gustäbel [EMAIL PROTECTED] Those who would give up essential liberty, to purchase a little temporary safety, deserve neither liberty nor safety.
