Storage quota
 

– Look at the Personal page to see what your quota is, and how much you have used. It may be helpful to understand how your quota is calculated.

– Metadata (thumbnails, temporary files, cache, and encryption keys) takes up about 10% of disk space but is not counted against user quotas. Some apps store information in the database, such as the Calendar and Contacts apps. This data is excluded from your quota.

– When other users share files with you, the shared files count against the original share owner’s quota. When you share a folder and allow other users or groups to upload files to it, all uploaded and edited files count against your quota.

– When you re-share files shared with you, the re-share still counts against the quota of the original share owner.

– Encrypted files are a little larger than unencrypted files; the unencrypted size is calculated against your quota.

– Deleted files that are still in the trash bin do not count against quotas. The trash bin is set at 50% of quota. Deleted file aging is set at 30 days. When deleted files exceed 50% of quota then the oldest files are removed until the total is below 50%.

Note:

– When version control is enabled, the older file versions are not counted against quotas.

– If you create a public share via URL and allow uploads, any uploaded files count against your quota.
