Nice app. I never really used anything like this before, I always renamed files individually when editing (video, audio, and photos).
I use it mainly when backing up to external HD's, I can tag the files by date, location or whatever makes searching and indexing simple.

I would like to see an Undo button in case of user error on the input. It may already be there but I have yet to find it, if anybody knows I would appreciate it.

Don't know if anybody knows this, as I came across this quite by accident. I have been able to rename files, folders etc. by right-clicking the name of the item, then select get info. When the info window opens, I just click on the name of the file/item to activate the name line and just change it. Call me dumbo?

Upgraded to Lion and could no longer use my long-time standby Renamer for Mac. Tried a few others, but Rename works like a champ, even better and quicker than my former application. Five stars and thank you to the developer.

Program does exactly what it needs to do, nothing more, nothing less.
Perfect!

What a great app. I was just about to pay for a shareware app, but found this one. It's actually better - it does what it's supposed to. Great!

A lovely app, and I applaud the developer for keeping it free.

However, Rename (and perhaps my idiosy as well) caused a major problem. Using the OS 10.6 Finder's own 'Make Alias' command, I made a new folder located in the Documents folder that only contains aliases of all my applications (for use as a launcher in Classic Menu's Apple menu). However, that process added ".alias" to the end of all my applications' names (e.g. "Safari.app" became "Safari.app alias"). So, I used Rename to remove the last 6 characters from all of my applications' aliases, but that resulted in all my apps (not the aliases) being converted to FOLDERS because Rename removed all of the ".app" extensions because Rename performed that operation on the WRONG FOLDER: Even though I dragged and dropped all of my applications' ALIASES from my Classic Menu Items folder into Rename's file list, Rename ignored those aliases and instead renamed everything in my Applications folder! Now I have to use Rename again to add back the ".app" extensions, but then I must go through all of them to fix the name of all the folders and ReadMe files that were in my Applications folder when I ran Rename.

My point is that this is powerful software, and it can majorly screw up your system if you don't test it on a few unimportant apps, folders and other files before you batch-Rename anything. Lesson Learned.
