7zip process cannot access the file because it is being used by another process

Problem:

I tried to compress a set of files via batch processing. Some of these files were currently opened by another process, so I encountered this problem.

7zip works as designed to skip those files, because an opened file could be uncompleted in the moment where we are trying to read it for compression, so its best practice to skip them.

Solution:

7z a -ssw archivename file_to_be_archived

 

or for older 7z Versions

 

7z a -x!TP archivename file_to_be_archived
