My files are fine, only the applications don't respond. For testing, I limited the number of folders to 200 folders and 605 files. Added in a second and merged in a second. Encoding and file structure intact (undamaged)!
I will gladly use third-party applications, only that I do not know the program. I have tried many but failed to merge or as I said, the application is not responding (hang). Merging piece by piece is also pointless. I just want to have one file and do not want to combine with some small parts of files and waste unnecessary time on it, for some small parts. -- <https://forum.pspad.com/read.php?2,73834,73844> PSPad freeware editor https://www.pspad.com
