Blocking a Google Drive sharer limits further sharing and access between the accounts, but it does not retrieve files already downloaded or replace a security investigation. Check the account and intended effect before blocking a legitimate collaborator.
Understand the documented effect
Google says the blocked person cannot share files with you, you cannot share with them until unblocking, and access to each other’s files is affected. Comment notification behavior has exceptions, including subscriptions to all comments.
For work or school accounts, Google documents restrictions on blocking people in your own or a trusted domain. A missing block option may therefore require an administrator route instead of another account.
Block the intended identity
From Drive’s computer interface, identify the file owner and use the current Report or block action. Google also documents a block route from a legitimate Drive sharing email. Verify the account where the block is being created when several identities are open.
Do not block a familiar display name without checking the associated address. A spoofed or unexpected message may need a different report and account-security response.
Verify and retain necessary evidence
Google notes that blocking changes may take a short time to apply. Review the resulting account block and any needed project access. Use the supported Google Account blocked-people controls if a mistaken block must be removed. Independent copies, screenshots, and content delivered through another service are not recalled. If the problem is one unwanted item, spam reporting may be the appropriate separate action. For a workplace incident, preserve relevant evidence and coordinate with the administrator rather than treating a personal block as complete containment.
