Auto-delete certain file extensions on my phone? How do I make my phone automatically delete certain file extensions? I'm on ICS, rooted.

For example, after connecting my phone to my mac, it will leave a .trashes file and other "." folders on my SD card. I want to make it so that the phone checks regularly and removes those extensions that I define. Another use case scenario is when I'm using an emulator such as GameBoid. I accidentally click on the Quick Save option and now there's a rogue *.ss0 file on my SD card. I want them deleted too.

I just flashed a new rom to my phone so I haven't re-downloaded Tasker yet so I also wanted to know if there's already a working solution around.
I wrote an app that removes it, called "Trashes". 

It can be found on XDA.
