@PeterJones Thank you. I just found this forum after searching about the multiple line issue. I’ve been using Notepad++ for years, fantastic program. First text editor I’d found that did search and replace on end of line charaters since good old Wordstar.

@Dervars14 Just checked and unfortunately the undo, ^Z, does not work. This used to be a more common occurance in the old days, Prior to Windows 7 and back in the DOS days, there was no checking to see if wanted to keep a file, it just got overwritten even if a totally different file, but just had the same name. The way we used to get around this is with a recovery program. The good thing is for a long time, whenever you save a file, it actually saves it to a different area of the dirve, precisely for this kind of incedent.

First important thing is don’t do any work on that drive, if the data is still there, it is not protected, the more you use the computer, the more likelihood those clusters of the drive will get overwritten.

I don’t think Windows has any internal programs, other than the Recycle bin, which is no use here, as overwritten files aren’t placed there. There is a free program called Recuva, from Piriform, the same people that do CCleaner. If possible, try and download this on another computer to a USB drive, as I said, the more work you do on the drive, the chance of losing the data.

The other good thing with using another machine, is you quickly play around with recuva, it is very basic program, the results are in table form, so easy to rearrange. You can save any detected files to the USB drive as well. If you get the file back, then just replace the current one. And this is the way to all learn to do backups more regularly, which reminds me.

@PeterJones
Hello that first option won’t work as I’ll have no idea which duplicates were removed.
Tried method 2, showered red for all entries that were different and white for duplicate, so used hide matches instead of hide all diffs, this his the white entries, need to do some more examples to be certain.
When I perform these actions it appears to change the file entries, in the text file does that make sense.

Just re-read your post, not sure if I’ve made myself clear about what I need.
I have 2 files, DocMaster with all my music, a second DocNewMusic, which has a list of new music but also contains some tracks already listed in DocMaster, so I want to delete all entries in DocNewMusic that already exist in DocMaster, think we are on the right track, but not certain, the procedure is deleting the correct entries.
Thanks so much for your perseverance and help. I know some visual basic, but not enough experience to write a plug in, my son writes in Unity, if he had the source code for the Compare plus plugin, maybe he could make a plugin to do what I need in one action.

Thanks

Only downside is doing this for all custom languages (i.e. 10 in my case) effectively duplicates them and makes the Language menu quite cluttered and hard to use.

It would be nice, if UDLs would be sorted within the preinstalled languages, but as far as I remember this wouldn’t be trivial to implement…
