I'm using the command line version 9.20 of 7zip. I wrote a little program that loops through specific files and add the files (one by one) to a specific archive. Sometimes the files will be added correctly to archive, but on the other hand it can happen that when i add some files to a already existing archive, then only the last added will be in the archive.
I tried it with the "a" command (if the archive not exists) and with the "u" command (if the archive already exists).
Please help me
Problem solved, my program was too fast ;)
