The ACE file extension is used in connection with Aces200, a currently obsolete bitmap viewing and editing program. At the moment, the ACE format is compatible with a limited number of image handling programs, so the best way to deal with it is by converting it to a more popular extension.
The quick and simple way to handle your files is to get a quality piece of software, such as reaConverter. This software is extremely efficient in managing a wide range of batch conversions. As you will soon realize, reaConverter will help you avoid spending countless hours trying to figure out how to convert multiple ACE files as once.
