Subtract 1 from the number at the end of filename

Hello Den4b, what about subtract 1 value to the end of the files:

IMG-20150818-WA0000.Jpg

IMG-20150818-WA0006.Jpg
IMG-20150828 WA0009.jpg
IMG-20150828 WA0011.jpg

The ones that exist like "IMG-20150818-WA0000.Jpg" they can became "IMG-20150818-WA0000-01.Jpg" With "-01" at the end.

Thanks.

PS. Nice job on ReNamer. Perhaps you should change "Pascal Script" with "Python Script".

Your statement and your example seem to contradict each other. Can you clarify if you want to append a number at the end of filenames, or you want to actually modify the existing numbers in the filename by decrementing them by 1 ?

It would also help if you provide a complete list of desired new names for your example filenames.

Hello, I would like to decrement 1 to the end of the files before the extention.

The think is that I copy twice pictures from my smartphone from the app Whatsapp and I don't know why but the second copy increment the name of the files by one. Now I want to be sure that they are equal to be able to delete the dupes.

I see that exists files that ends in 00 that ones I want to differentiate since when I decrement one when is 01 will go to 00 and became with the same file name .

See the size of the file is right, but the name is increment by one:

Thanks.

It sounds like you are using a wrong tool. I would recommend using a duplicate file finder tool to eliminate your duplicate files, and then, maybe, clean up the remaining filenames if there is still a need.

A quick check for binary-duplicate files can even be performed by ReNamer by substituting the new name with an hash of the file (like MD5 or SHA1).

> Insert "C:\Temp\:Hash_SHA1:" replacing current name

After adding this rule you will get warnings about binary-duplicate files, due to identical hashes, if there are any. You could then chose to delete or move the duplicate files.

den4b, thank you for the help.

I search for SHP1 using this tool and then renaming some files with your tool.

Thanks.
