For example someone emails you a link to a shared PDF on Google Drive.
Is there a way to add it in your Google Drive instead of downloading and uploading it manually?
Also it would be great if the owner decides to delete/revoke access I would still be able to use it.
Best Answer
After this there are two options:
Click 'Make a copy', which will locate a copy in your 'My Drive' folder, but that copy will not be synced with anyone else but will be yours even if it is deleted by others
OR
Click 'Add to My Drive' which will save a copy to your My Drive folder that will be synced but will also disappear if the owner or another editor removes it.
Of course, you could always do both.
