I'm sorry to say that I have not tested under Lion.

But It should work. If you have trouble, I will fix it as soon as possible


Works without any problems. Now I just have to figure out regular expressions... :-)

I'm looking to rename a bunch of files with file names like


All I really need is the middle part of the file name s123 and the extension .txt. The file name could be easily generated searching for the regular expression .*(\d*).* and replacing it with \1 turning it into 123.txt

Unfortunately this software can not do that. It doesn’t make use of \1 in the replace string. Instead it just ignores the \ and writes a single digit 1.

Did you just copy paste this to all the renaming apps on MU? I just checked namemangler and you have the same post exactly submitted. Please make your comments unique to the app. Show that you actually are taking the time to review the individual app not just post the same thing across multiple apps that do similar things.

PowerRenamer have ability you want.

You can use references to strings which matches groups in the regular expression.
Use $1, $2 ... instead of \1, \2...

For your example, try following setting.

mode : regular expression
search for : \D*(\d+).*(\.[^.]*)
replace with : $1$2

Fantastic software. Works great, when others have been too weird to use.
Thank you!

Search and replace works well, but numbering seem to have problems: "AppleScript Error: script FileSorter doesn't understand the is_invalied_list message. (-1708)"

Hey! This is one damn little useful app! Excellent for those quick little jobs where launching something like a Better Finder Renamer is too much for the task in hand. Highly recommended.
