Thank you very much, macropod!
As for the first find/replace problem you found, I think you are correct and something got mixed up. IŽll 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!
