There is a folder it has many part files and relevant assembly files. That means it is a mixed folder. When moving all relevant part files and assembly file in a separate folder by using pack and go, is it possible to make such part files and relevant assembly file, at the same time removed in the mixed folder?
What you could do is as follows:
1 - Pack&Go to a new folder
2 - Copy all the files (obtained from Pack&Go) back to the original folder (overwrite the existing ones)
3 - Sort by "Date modified" in Window Explorer
4 - Delete all the latest files (Date and Time of "Copy" operation)
I know it could be dangerous. Just double check the numbers of files to be deleted matches the number of files in Pack&Go.
Hope it helps.

No they will not be removed from the mixed folder.
