Here is what i would like to do. I want to rename all files and fields to Sentence case ie:

CC music factory - CC Music Factory. The problem is that when i do a case conversion it also changes the CC to Cc. If there a way that i can tell the program to ignore any text that have two consecutive Capital letters to leave them alone and continue to change the case for the rest. I would like to do this globally so i don't have to go back and do them one at a time. Please help.

Hello there!

I think i may have find a practical work around for your problem.

**1ST STEP - Create a Action Group called Mixed Sentence w/Repeated Chars**

**Click on "NEW" button and follow the steps bellow:**

Actions -\> Replace with regular expression

```
                 Field: (It works with any of the fields)

```

Regular Expression: (.)\1+

```
      Replace with: $upper($1)$repeat($upper($1),1)

```

**2ND STEP - Click again on "NEW" button and follow the steps bellow:**

Actions -\> Case Conversion

```
                 Field: (It works with any of the fields)

```

Case Conversion: Mixed Sentence

```
The third field should be left blank

```

There, you learned how to create a action group with two useful actions that will solve your problem! 🙂

I really hope this helps because i've spent a couple hours learning following this useful website:

[guiStuff - Regular Expressions: Part 3](http://www.guistuff.com/articles/regexp_full_3.html)

Take care! 🙂
