Backup creating folder many times

[Assadbintahir]

Backup creates many folders for documents, images, audio, video etc as many times as the backup button is clicked.

Expectation is that it only creates the folders for once and then backup files in them instead of creating new folders each times.

I have fixed this issue. Now if a folder is already created on drive, then it is not created again and again with each backup.

I have created the pull request as well.
