How to Use GAT Unlock for File Management

File Management – Changing ownership or file access rights

GAT Unlock is tightly integrated with the powerful search and filter options available in GAT+. This means you only have to do things once.

In this example we are going to find all the spreadsheets owned by the group ‘sales’ that are shared externally, then we will remove the external sharing and change the ownership (on all the selected files at once).

TIP: Always narrow the file request with a search first – saves time and makes approval simpler.

Step 1: Click on the ‘Apply custom filter’ button in Drive Audit.

Step 2: Select the following option:

  • For the filter type select User/Group/OU search, we will enter the ‘Sales’ group in this field ‘Local User/Group’, make sure to enter the full email address.
  • Click the checkbox option ‘Owned’, this will show all the files owned by ‘Sales’ group. Otherwise, it would show all of the files associated with ‘Sales’ group, were Sales shows up as Owner, Editor or Reader.
  • In the filter definition area, select the parameter Type equal to Spreadsheets and to add another search parameter click on ‘Add rule’ button and select ‘Sharing Flag’ to ‘Shared Out’. Selecting shared out will only focus on files leaving your domain.  

Step 3: Next click on the ‘Toggle Selectable’ button, this will allow you to select files individually or all of them at the same time.

Note: You can not perform actions on a ‘Suspended’ account.

Step 4: Click on the button ‘File operation’ and then select the ‘File Management’ option.

Step 5: In this example, we are removing external access to the spreadsheets and making the manager the owner of all the files.

When you click on the ‘Send request’ button, an email is going to be sent to your security officer.


If the security officer approves your actions, they will be executed and you will be notified.

If permission is not granted by the security officer, you will also be notified and no actions will be taken.

Access Permissions Granted – How to silently copy or view files

We are going to use a powerful search feature inside of GAT+ Drive audit to identify the contents of documents we’re going to investigate. This feature is called the ‘File content text search’. It allows admins/delegated auditor to use a word or sentence to search through all of the files across the domain and to return documents which contain them.

Step 1: Click on the ‘Apply custom filter’ button.


Step 2: Enter the word or sentence to return files which contain them. Select the user’s account you want to search through you can leave this field blank to search your entire domain’s Drive or enter a user, Google Group or Org Unit to search through them only.

You can also use multiple rules in the definition section of the Apply custom filter. I used the Updated search parameter. Once you click on Apply button the search will begin.

It will take a few minutes depending on how many files you have across your domain.

Step 3: Select the files you are interested in, remember that these files contain the sentence “private and confidential”.

Step 4: Click on the ‘Files operation’ button and then select ‘Access permissions granted’.

Step 5: Next we will select a date in the future, we will have access to these files until this date. You have an option to write to your security officer explaining why you need access to these files.

Send the request to the Security Officer(s) for approval.

The following email will be sent to the Security Officer.

The Security Officer can click on the link in the email and will be taken to the approval area(Grant) in GAT+.

When the Security Officer grants access an email will be sent to the requesting Administrator/delegated auditor informing them. The Administrator from the ‘Access permission granted’ menu can see the full list of their access requests along with the time left for each request to remain valid.

Once the request is selected, the requestor can download documents or view the contents silently without the owners’ awareness.
