OVEN KING  There is a need for good conversion software for various filetypes to mp3 and other common formats. After unsuccessfully using a combination of Xact and iLas to convert .flac files to mp3, I tried All2mp3 with limited success.

The drag and drop interface is simple. As other reviewers have mentioned, progress indication is necessary and setting destination location should be part of the application as well. I also found All2mp3 inconsistent in operation; in several cases I converted a file unsuccessfully in a batch conversion and then tried converting it by itself and was able to get the conversion to work. Otherwise, when converting multiple files some will work and some will not. I also found issues with filenames, specifically with non-alpha numeric characters in the filenames. When I removed parentheses and punctuation in filenames that previously did not work, the conversion suddenly worked.

Overall, the simplicity is nice, but just a few more features and some effort to address the inconsistency issue would make this far more useable.
