Default QUERY: similar file finder (not duplicate file finder)

I know there's so many of these Duplicate File Finders, but am looking for a "similar text file finder". I have thousands of scripts (3rd party, and hand-written, etc), and over time scripts get copied, enhanced, modified and hence there's many forks/branches/versions of the same script.

Am surprised no one has done a "similar text file" finder. This would be so useful in finding all derived scripts.

depending on the file type, window's search function can search inside word/excel files

http://www.icetear.com/ is one I use too, small enough to keep on HD incase I need it
I had one that searches inside text files too but I lost it, I'll dig around and see if I can find it :S

edit:wait, do you mean duplicate text inside files? Or just finding text that you know are in A file?

Something like AntiTwin perhaps?

If you set it to "Compare content" and "Byte by byte" then you can enter a percentage similarity for it to look for.

I just tried this out (I never had a need to locate similar text files before) using two text files containing the lyrics of a song. One file untouched and in the other I replaced 2 lines with "blah blah blah". When I ran AntiTwin it flagged the two text files as "86% match".

Not exactly what you're after I know but maybe a step in the right direction?

Thanks for the speedy reply.

What I mean was, the comparison of text files.

Text file A
Text file B - was a copy of text file A, but with a few lines changed
Text file C - was a copy of text file A, but with one line changed


etc.

closest things off the top of my head might be to look for anti-plagerism programs. They are made to compare files against similar texts. I don't know any off the top of my head though, never really needed it :S

I've just been doing a little more hunting purely out of curiosity, and came across ExamDiff.

It doesn't search for similar files, rather you point it to two text files and it will display them side-by-side with any differences highlighted. It worked perfectly on my two test files.

The free version only allows two files to be compared and has other limitations compared to the licensed version but in combination with AntiTwin it might help you get the results you want?

*Edit; Eyeb you just reminded me of this thread - https://www.techsupportalert.com/fre...ilarities.html.

Perhaps the softare suggested in Post 4 would help, I've not tried it myself.

I found the one I was talking about that I said I couldn't remember
http://lmadhavan.com/software/archive/ get the snowbird program

It work's like voidtools everything with the added feature of searching file content too. It is SLOW, doesn't index... but if you want to search for a line of text in multiple files, it works well. Just slowly.

edit: it won't work if part of the line is changed since it only searches for exactly what you search for :S. The plagarism thing might be best if you want like a 90% match instead of 100%
