What you need
Steps
Create a Google Cloud project, turn on the Drive API and the Photos Library API, then make an OAuth client for a desktop app and download the credentials file.
Open the Accounts page and connect each Google account through the OAuth sign-in. Approve the Drive and Photos permissions so the tool can read quotas and move files.
Check the quota bar for every connected account, then open Rebalance and pick the account that is nearly full as the source.
Start the rebalance. It scans the source, builds a plan and shows it to you first. The run is a dry run by default, so nothing moves until you confirm.
For photos, open the Google Photos picker, choose the albums or items to move, then select the destination account.
Watch the progress screen until transfers finish. Each file is hashed with SHA-256 before the original is trashed, and a crash-safe resume picks up where it stopped.
Check the ledger for every move, confirm the files appear in the destination Drive, then leave the originals in trash for 30 days before emptying it.
Tips and common mistakes
Keep the 1 GB safety buffer per destination so uploads never fail on a full account.
Shared files are skipped by default, so move those yourself if you need the space.
Gmail is never touched, so a heavy inbox will not free up any Drive quota.
Do not empty the trash straight away, since it is your only undo for 30 days.
Questions
Does Spillover delete my files?
It copies each file, checks the copy with a SHA-256 hash, then moves the original to trash. You have 30 days to restore anything.
Do my files leave my computer?
No. The tool runs locally on your PC and talks to Google directly, so nothing is uploaded to a third-party server.
Can it free up space used by Gmail?
No. Gmail is left alone, so only Drive and Photos data gets rebalanced between your accounts.
