Temporary file on opening .xap file and can't recover

[WPCentral Question]

I opened .xap file using File app, but nothing happened just lost size of app from phone memory. It's showing as temporary files in Storage Check. Tried clean that up with Storage Check and Storage Sense. Nothing happened. Is there any way to recover it?

Recover it, probably not.
Have to use store, local files to install xap.
