AddFile and path-based
AddFile are actually slightly different. For example, the path-based variant persists the file's creation/lastmodified/lastaccessed dates, which the stream-based variant doesn't.
However, if one produces a ZIP archive that is less compatible than the other, we will surely look into that and try to solve the issue. Would it be possible to let us know the names of the tools that don't recognize the ExtractToStream/AddFile target? Thanks!
