When I sync a local folder with a google drive folder I get an error aboud google drive files, how can I filter google files?
The error abuot the "Untitled document" google file:
Impossibile leggere il file "gdrive:\alexgiov.mail@gmail.com\test\Untitled document".

Il server ha restituito un errore:

],

}
}

It seems all Google Docs files have 0 file size when listed in FreeFileSync. I'm not sure if it would be useful to automatically exclude them by FFS, even though they cannot be copied as normal files.
