Hello,
I had a quick look with SysInternals' ProcMon.
Given a B.ZIP file inside an A.ZIP file, the sequence is roughly the
following:
- User clicks on A.ZIP
- Explorer opens A.ZIP and extracts content into a temporary "A" directory
- User clicks on B.ZIP inside A.ZIP
- Explorer opens B.ZIP and extracts content into a temporary "B" directory
- Since A.ZIP is no longer referenced, temporary directory "A" is deleted
- User clicks "back"
- "A" directory not found, explorer closing
I feel you'll have a hard time trying to control EIP ;)
