For computer science, are the files corrupted or corrupt?

When it is said that "the files are corrupt", it isn't clear whether the files were corrupt from the time they were created, due to problems with data entry, ETC., or that the files became corrupt after a problem.

Saying that "the files are now corrupted" implies that there was a clean state for the files in the past, and that they need to be returned to the clean state for the software to work properly.

Either usage is fine. Just as you can have a politician that is corrupted and a politician that is corrupt, so you can have a file that is corrupted and a file that is corrupt. Both terms have established usage; it's a personal preference which you use.

I think files are generally corrupted. You could probably say corrupt, and everyone will get what you mean, but I'm pretty sure corrupted is correct.
