Delete folder on SD card

I have a 8 GB sd card and its just about full. I was looking through it on my computer and found a folder called Android that looks like it has data from some of the apps i have installed. But i just moved all the apps to the internal memory. Would it be okay to delete this ? Otherwise i cant figure out whats taking up all the space. Pics is about a 1GB, music is about 2GB, this Android folder is 3.5GB . Not sure if this helps but here is what it looks like once you open Android\data .

i would save it to pc before deleting

Check the OOB folder which was located in Android folder. If there any file exists, copy that file in to internal memory. Otherwise you will lose your application.
