Where are Google Drive files stored

Google drive stores the offline files in a folder called... android/data/com.google.android.apps.docs/files/pinned_docs_files_do_not_edit/ in that folder u will find the desired files. Please be aware that... The files that you will find can be of two formats.. 1) encrypted 2) open type

If you have left unchecked the option to encrypt (by default in google drive) the files that u downloaded will be visible, but not accessible by the standard reader. every attempt to read it will be result in a failed operation. But ... if you DISABLED the encryption in google drive, u will be able to open freely with any type of reader.
