MAPIDo “Shared With Me” Files Use My Google Drive Storage?
Seeing a file in Shared with me does not mean the file's stored data counts against your quota. Google says shared files normally count against the original owner's storage, with your quota used for copies you create or files you add yourself.
No. Google says files shared with you normally count against the original owner's storage, not your Google storage. Your storage is used if you make a copy of a shared file or add your own files to a folder someone shares with you.
no
The answer
No. Files that are only shared with you normally do not use your Google storage.
Why
Google states that files shared with you count against the storage of the person who originally owns them. Your storage is used if you make a copy of a shared file or add your own files into a folder someone shares with you.
When it is usually OK
- The item is owned by someone else and simply appears in Shared with me
- You have viewing or editing access but ownership remains with the original owner
When you should not
- You make a copy of the shared file
- You upload or add your own file into a folder someone shared with you
Risks and exceptions
- Making unnecessary copies can consume your own storage
- Removing a shared item from your view does not delete the owner's original file
Best practice
Check whether you own the file before assuming it is using your quota, and avoid making copies unless you need an independent version.
Alternatives
- Keep using the original shared file when a separate copy is unnecessary
- Check Google storage usage to see which owned items consume your quota
