FileType is an application to change the file types (type- and creator-codes) of files. You can save the file types you frequently use in a database so you don't have to remember them. It's very easy to use.

In fact, FileType is pretty much self-explaining to most users. Just click around and you will see that most of what you have expected to happen, will happen. Nevertheless, you might not see everything that is possible. That's why there is a Read Me file. :)

Note: FileType can only change file types, it can not change file formats (e.g. GIF to JPEG, DOC to PDF,...). Have a look at the definitions of "file type" and "file format" if you are not sure what the difference is.

System Requirements

FileType runs on Mac OS X v10.0 or later and on Mac OS 8.6 or later with CarbonLib 1.3.

This application is freeware for non-commercial use. It is provided "as is". You use it at your own risk. Contact me for information on commercial licenses. You can copy it and give it away (redistribute) as many times as you like (the more, the better) as long as you don't modify any part of the download. All I expect is a short email in case of redistribution, explaining where you redistribute it, and - if possible - a copy of the media (i.e. magazine). You will get my postal address by email.
