Finding a specific file type is made easy with GAT+ using the powerful options available in the filter section.

In the filter area, you can use the search for parameter mime-type.

Here is a list of type mime-type searches:


  • application/photoshop

Click on the ‘apply custom filter’ button.

You can then apply the following search parameter.
