What are the characters added to the file names for Google Drive files in Koofr?

Google Drive allows the same filenames to be used for multiple files (or folders) inside a folder. Since no other platform we support allows that (including ours), errors might have occurred when trying to copy/move/download such files/folders inside Koofr. So, in case where there is more than one file with the same name in a folder, you see unique 8 characters added to the name inside Koofr. This is for representation in Koofr only. File name on Google Drive will not be changed. You may also notice folders and files containing "illegal" characters (e.g. /) being displayed with substituted characters (2017/06 will be displayed as 2017-06). These name changes in Koofr allow all operations on these files to successful and without errors.
