You can restore accidentally deleted or corrupted information that is needed to download the information from the sensor and store it with the trial it was captured with.

To do this, you can copy the information back from a trial-specific file that is saved at the end of a capture.

**To restore missing information to a sensor: **

1. Plug in the sensors that have data on them that is deleted or corrupted and that you want to restore.
2. In the **Communications** panel, select the **IMeasureU** tab and click **Show Advanced**.
3. In the **Trial** list, select the required sensor(s).
4. Click ** Rebuild Transfer List**.
5. In the **Rebuild Transfer List** dialog, click in the **Folder to process** box, enter or browse to the folder to process and if required select **Look in child folders** to process all of its subfolders.
  Note that the folder you select does not have to contain the trials, for example, the folder can be the parent of multiple session folders. In this case, you would select **Look in child folders**.
6. Click **Continue**.  
The trial-specific data is copied and you can now download the restored information from the sensor.
