100+ Megabytes of .BAH#### "hidden" folders in ~/desktop folder

Check each application you run from a second account created in Apple menu -> System Preferences -> Accounts to see if any creates those files.

If not, and there is no software that could logically write those files to your desktop, backup you data first, and then try deleting them. Sometimes these files might be locked, in which case you might need to use Secure Empty Trash from the menu which has Empty Trash, or even my software.

explains various means of backing up your data in case some of those files prove to be important for something and you need them back. And here is the link for my Force Empty Trash program:

Which should you be more afraid of? The prospect of losing all data which may cost thousands to recover if it works at all, or the prospect of just losing a little in case one small portion of the backup didn't succeed. It is not a question of if you will lose data, but when.

.BAH### folders are created by BOMArchiveHelper.app:

/System/Library/CoreServices/BOMArchiveHelper.app

BOMArchiveHelper is the background application that creates the archives of the "Create Archive" command in the Finder.

If these folders are dated, and Activity Monitor doesn't show any "BomArchiveHelper" processes, then they should be safe to delete.

Hope this helps....
