With this function you can copy the contents of a locally saved file to a file that is synchronised with the Steam Cloud. The local file must exist before using this function, and it will return a value of 0 if it fails for whatever reason and a value greater than 0 if it succeeds.
|steam_filename||The Steam Cloud file to copy over.|
|local_filename||The local file to use to copy from.|
The above code will copy the contents of the file "Koala2.png" to the Steam Cloud file "rm_koala.png".
