If you use Gmail then you’re aware of the fact that, all the trashed emails are removed automatically from your account after 30 days. Right? The company now updated Google Drive with same functionality.

Google Drive will delete all the content including photos, videos, files, audios, etc., after 30 days from the ‘Trash Bin’. Earlier, all the trashed content remains in the Trash bin until users delete it manually. But this behavior is going to change soon. Any existing content in Google Drive will be deleted 30 days after October 13, 2020.
Google developers had informed about this massive change in policy on their G-Suite Updates blog, for detailed information visit Google Blog.
The new Policy change notes are as follow:
Admins can still restore items deleted from a user’s trash for up to 25 days for active users.
Retention policies set by admins in Google Vault are not affected by this change, unless they become obsolete as they are now redundant. Learn more about retention rules for Drive.
These changes affect items that are trashed from any device and any platform.
Files deleted via Drive File Stream will be purged from the system trash after 30 days. There is no impact to Backup and Sync behavior.
Files in shared drives trash are already automatically deleted after 30 days.
Items in trash will still continue to consume quota.
