Capitalizing the first word in a filename

I have a huge collection of zipped karaoke files with names like
Dk004-05 - Foreigner - Waiting For A Girl Like You.zip or Lg038-10 - Kinks, The - Ape Man. What I'd like to do is change the first word of the file name (ex: Sf004-01) to all caps (SF004-01). I know I have to use one of the "set pattern" options but I'm not sure what statement to put in the pattern box. I've been using Advanced Renamer for a whole 4 days, so I'm about as green as a spring tomato.

TIA for any help!

Try the New case method selecting "Set pattern to upper case" and "Use regular expression" with the pattern: \w+

That set everything to all caps.

Never mind - I discovered that if the file directory name is the disc number I can use <DirName:1> to change the file name and still keep the track number.

Sorry about that - the pattern should have been \w+-

Hi, I want to ask a related question. I have a few folder names that have ALL CAP words in the middle of the folder name, while the rest of it is in "first letter uppercase" format. I want to make these words also just "first letter uppercase" without affecting the rest of the folder name. How do I achieve this?

EX:

From: Indonesia_2011-09-08_BALI_Shrimp Restaurant_x112
To: Indonesia_2011-09-08_Bali_Shrimp Restaurant_x112

Using "set upper case first letter in every word" does not set the remaining letters of the word in lowercase.

Use another instance of New Case to "Set lower case" before you "Set uppercase first letter".

That will also set X in"x112" to upper case - to deal with this add a third instance of New case using "Set pattern to lower case", with the regular expression _\w+\d*$

Ah, Thanks. I had figured this out. I was hoping there was a less method-y way.
