I'm a mac user. I want to edit the file names so that there are capital letters for artist, album, etc. But the Action button I used on a PC before, CD-R, does not work when I use it on my mac. How do I fix this?

Could you be a little more specific?
Why do you use an action to get tracks for a CD instead of an action to convert the case if you want to capitalize letters?
To create filenames from tags can be achieved (best/easiest) with the function
Convert\>Tag-Filename.

If I use the Convert -\> Tag Filename option that does create the file pattern I prefer. But it will not change the the artist, album, or titles to words with capital letters. When I choose the Action option, at least on a PC, it capitalizes the first letter of each word, so that the artist name is capitalized, the album name is capitalized and so on. On my Mac, this does not work. I have to manually go through each file and capitalize each letter, which is tedious and not practical when you have over 100 GB of music files you want properly tagged.

First is to to apply custom Case Conversion, which changes case to all fields except filename. In second step I rename files in format that I don't use, for example %artist% - %title%, then in third I rename to format that I use. If the filenames aren't in format that I use (that's $num(%track%,2) - %title%) then second step isn't necess…

> The method I have used in the past versions of mp3 tag were to go right to the filename column, double click on individual tracks so they are highlighted with a cursor & edited the songs to have caps for the 1st letter of each word. I would also do this same thing, & double click on the title filed column & make the 1st letter of each word a cap. This had worked in earlier versions of mp3 tag on a PC, now I am using this version on a mac running windows xp pro through parallels desktop. I have…
and many more - use the search word "mac case filename"
