well i can do that anyway - i can add lines of txt into the filelist.txt but i cannot look for duplicate strings afterwards which i would very much like to do

its easy with dos to add lines of txt just by merging 2 files together
so if 1 file has the txt you want to add (add.txt) & the other is what you want to add to (filelist.txt)
you would do this

copy filelist.txtm + add.txt

this will merge the 2 files together

but we really need something to find duplicate entries :wink:

thx for help though
