Add & Replace vs. Move
-
I noticed that two of the file types (7-zip and Tar) do not support any options other than “Add and Replace” when creating an archive. I’m curious why the Move option isn’t available. As far as I knew, the only difference was that after creating the archive, the original files were deleted from the disk. But to me it doesn’t make sense that this wouldn’t be supported under Tar and 7-zip…so what’s the real difference?
-
It is because tar and 7zip engines do not support move option. It has to be built-in in the engine, or it would be nearly impossible to properly verify that file has been compressed properly and that PA can safely delete it.
thanks,

Alright, thanks. Additional question then, how is the the free 7-zip compression program from sourceforge supports Update and Add and Freshen options in addition to add and replace, yet PA only has add & replace for 7z? I assume they all use the same compression engine since it’s open source… Or is this another thing that will be available in a future release when the dll is updated?

Currently we can not use move function. It is possible that we could use it with new support in 9.5, but I am not sure yet. We would also have to test it extensivly to make sure it works only when it should, so even if we are able to add support for it, we might not if it is not 100% reliable.
In general, if it was up to me, we wouldnt have move function at all, because there is always an possibility for end user to lose their data.
Obviously Igor Pavlov who created 7zip has a lot more insight into how it works than what we do, so 7zip support will always be the best inside 7zip itself :-).
thanks,
