Help!-Cab files disappeared from Internal Storage

[majorassface]

Hi all,

I need help, I'm not sure what I did or installed but for some reason it looks like all of the cab files on my internal storage have disappeared. I was playing around with a few apps this morning on my way to work, apptodate,PDM,Device Update trying to see if I liked any of them. I get to work and when I looked in my Internal Storage all the apps in /Internal Storage/CABs and Temp/ were missing. Luckily I have most of the things I use backed up on my work pc but I can't help but feel I lost something. Can anyone help? Did one of the apps I installed cause this?? I couldn't get device update working, PDM and apptodate I've used before but I never ran in to this.
