thanks, if this works for my 300 files with same problem you get a new customer

edit:
you got me

edit:
you got me not, your payment system doesn't want me

just downloaded it for test, don't find solution yet:

have lot of files, with text string like

aaaaaxyxybbbbb (total 20 lines each file)

the part xyxy is changing in any file, but all files have same aaaa and bbbb before resp. after the changing part

I want to delete or replace the changing part ...
