Yes, it's possible to identify shared drives that have not been accessed recently, and there are a few methods you can use to gather that information. While there isn't a direct way to query Google Drive for last access in the Drive UI itself, tools like Google Apps Manager (GAM) or Google Workspace Reports can help.
Here are a couple of approaches:
1. Using Google Apps Manager (GAM):
GAM allows you to manage Google Workspace environments and can help you retrieve information on shared drives and activity. You can run specific queries to get file or drive activity, but it may require some scripting to check drive access times.
Steps:
Use gam print driveactivity to get a report of the activities on drives.
You could also export this data and then filter by timestamps (such as a year back) to see which drives haven't been accessed.
This method may not give you access directly at the shared drive level but will let you audit activity related to files within those drives.
2. Using Google Workspace Admin Reports:
Google Workspace provides built-in reporting tools under the Reports section of the admin console. You can use the Drive Audit Log to see file-level activities.
Steps:
Go to the Admin Console > Reports > Audit > Drive.
Set the time filter to the last year and review the logs for shared drives.
This will allow you to see file creation, views, edits, and other activities.
You can export this data for further analysis, identifying drives with no activity over the past year.
3. Manual Cleanup with Shared Drive Membership:
You can manually check drive memberships and confirm with owners/users about the drives they use frequently. It's less efficient but ensures you don't delete drives people rely on.
If you're unsure about removing a shared drive, you can always notify users first or archive the drive content before purging it. This way, you'll have a backup if anyone requests access later.
