Replace second + with _

[MightyMrMatt]

I have about 600K files with the following naming scheme:

someFile+1010101+1.jpg

I need to change the second plus sign to an underscore. I've tried this:

Match: (.*?)+(.*?)+(.*)
Replace: \1+\2_\3

But it doesn't show any change. What am I missing?

Because + means "match 1 or more times" in regex , you will need to take it literally by prefixing with \
You also do not need ?

Match: (.*)\+(.*)\+(.*)
Replace: \1+\2_\3

That's it! Thanks for the help!
