Thank you very much, macropod!
As for the first find/replace problem you found, I think you are correct and something got mixed up. I´ll look into it.
As for replacing "'" with itself, it seems that by copying the code here, the forum changed the html-way of writing "'", which I have in the txt files, automatically to the correct way of displaying the character, which is basically the same thing I am doing in the txt files. So it may seem unnecessary but at least to this one there is some logic

As for the code, there still seems to be a problem. I apologize if I did not understand correctly or if am being stupid here, but if I paste it into the VBA editor and then run sub "Main", I get to the part, where it asks me for the top folder. After selecting it, I get a runtime error 424 "object required" though. Do you have any idea why?

Also, could you change the popup asking to select the location to a fixed one in the code? I understand that your solution is much more elegant but the folder will never change and thus I can save a few more clicks during the day.

Once again, thank you for your help!
