# Auto Expire

Many people may have sensitive information in files on their computer that have not been looked at for a long time.  
Maybe so long that they are forgotten about.  
To ensure these files don’t become a security risk, files in a group can be set to be automatically purged after not being accessed for a specified period of time.


:::info
Purged files can be retrieved by a Forensic user, unless [permanently deleted](https://outline.suredrop.io/doc/archiving-settings-JQlq0YA1fc).

## Set files to Auto Expire

Files can be set to Auto Expire by group owners and users.

* Click on the *Edit Group* button
* Enter the number of days for files to be retained before they automatically purged
* Click the *Confirm* button

In the picture below, files in the **Customer** group have been set to automatically expire if they have not been accessed during the past 90 days.

When set, the **Auto Expire** period is displayed below the Group name at the top of the user interface.
