Been having some issues with the dreaded Market "invalid file" error. First, I moved the 01mdalvik file to the sd-ext folder. It cleared up my market issues, but now I have two huge dalvik-cache folders hogging up my internal memory. I can't move these. Is there a way to move these without reformatting and partitioning my SD card (currently there are no additional partitions)? I am running the latest CM7 build.
