If you use ROMVault or have a subscription to DATVault and want to integrate Retool into your flow, complete the following steps.

1. Add your Redump and No-Intro DAT files to a subfolder in your ROMVault DATRoot that is separate from your other DAT files. For example, DATRoot\Retool\.

   This is so Retool only processes these files and no others.

2. Configure Retool as follows:

   === "Retool GUI" 1. Open Retool.

   1.  Click **File**, and then click **Settings**.
   
   1.  Set the **Quick folder import location** to where DATVault downloads your
       Redump and No-Intro DAT files.
   
   1.  Close the settings dialog box.
   
   1.  Optional: In the **Paths** tab, enable **Replace input DAT files**.
   
   1.  Optional: In the **Options** tab, enable
       **Don't modify the input DAT file's existing header fields**.
   
   1.  DATVault only: In the **Options** tab, disable
       **Add MIA attributes to files**.
   
   1.  Set your preferences for the ROMVault DAT files in Retool.
   
   !!! Note
       If you use system settings, you might also have to change these settings
       there.
   

   === "Retool CLI" Use the following flags, along with the path to the separate folder you've set up for Redump and No-Intro DAT files. Add any other settings you want.

   * `--replace`:  Replace input DAT files with Retool versions. Only use this if
     you can recover the original DAT files from elsewhere.
   
   * `--originalheader`: Optional. Use the original input DAT headers in output DAT
     files.
   

After you've got your DAT files where you want them in ROMVault's DatRoot:

1. In Retool, click {:.inline-icon} Add DAT files recursively from your quick import folder to add your ROMVault Redump and No-Intro DAT files.

2. Click Process DAT files to replace the DAT files with those that have been processed by Retool.

3. In ROMVault, click Update DATs to load the Retool-processed version of your DAT files.
