Delme.bat
 

I found this file in Macintosh HD called "Delme.bat". Opened it in text edit and it said this:

(bowep is a folder containing the Best of Entertainment games, my attempt at installing it with Crossover. It runs the already installed versions just fine, though Jezz Ball doesn't have sound.)

What in the heck is this thing?

Sounds like a batch file used to uninstall the software. Batch files are essentially groupings of commands that can all be run in sequence by running the batch file itself. (They are Windows only.) Going line by line, I would say it is removing your Best of Entertainment games by running the uninstaller, then removing the folder they came in, then removing itself.

It's telling your computer to delete Z:\bowep\disk1\Uninstal.exe, then check if Z:\bowep\disk1\Uninstal.exe still exists. If it does, then it deletes Z:\bowep\disk1\Uninstal.exe and keeps checking to see if it's deleted until it's deleted, then it does something else, then deletes itself.

Don't quote me on that, I'm just guessing.

EDIT: Not only did Danny beat me to it, he said it in a way that made 100x more sense.

Ok, thanks guys. :)
I just deleted it, and the uninstaller.
