Zip for Documents directory throws error

I download my zip resources (spritesheets and maps) then I try to unzip them. If I use zip.uncompress from Documents folder to Documents folder, from the corona zip plugin, I get zip errors 100% of the time. Just event.isError = true without any debug.

It should be documented that you download into the cache and then uncompress into documents, if there’s a reason…but if the cache gets cleared my app can’t know if it has already downloaded the large zip files.

Any reason we can’t unzip from the documents folder?
