If you move it across devices, it is basically a copy+delete operation and all bets are off.

In fact, some apps use that to hide temp files and ensure they are cleaned up even in the case of an app crash: open() the file, then immediately unlink() it, giving the file handle back to the user. When the app ends/crashes resp. when close() is called on the handle, the FS can then free up that space. -- ----- stephan beal http://wanderinghorse.net/home/stephan/ http://gplus.to/sgbeal "Since tyranny's the only guaranteed byproduct of those who insist on a perfect world, freedom will have to do." -- Bigby Wolf _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
