It looks like I have found a treasure of wasted memory on my phone! I had to buy Root Explorer tonight to fix a problem I had. I discovered that the /data/dalvik-cache folder is holding files for apps I no longer even have. Some are system apps I deleted with Titanium. From everything I have read, there is no problem deleting everything in this folder since it is just a cache. For apps still on the system, it will just re-build the cache file when needed. So here is my question. Do any of the experts out there know about this? I want to make sure that I do not delete something important and mess up the phone. It looks like I might be able to recover about 10-15MB, which is much needed as I am getting low.
