MAPIDo “Shared With Me” Files Use My Google Storage?
Shared access and ownership are different. A file can appear in your Drive interface without becoming part of your storage quota if someone else still owns it.
No. Files shown in Google Drive's “Shared with me” do not use your storage simply because they were shared with you. Google says they count against the owner's storage.
no
The answer
No. Google says files in “Shared with me” use the original file owner's storage rather than the recipient's storage.
Why
If you make your own copy of a shared file or add files that you own to a shared folder, those new files can use your storage because you own them.
When it is usually OK
- Someone else owns the file and it simply appears in Shared with me.
- The file remains owned by the original owner.
When you should not
- A copy you create is your own file and can use your storage.
- Files you add and own inside a folder shared with you can use your storage.
Risks and exceptions
- A copy you make of a shared file or a new file you add and own can use your storage.
Best practice
Check who owns a shared file when deciding whether it contributes to your Google storage. Google says Shared with me files use the original owner's storage, while copies or new files you own can use yours.
Alternatives
- Keep the original shared file if you only need access and do not need your own copy.
- Check ownership before creating a copy when storage usage matters.
