# SDCX Conversion

Raw LiDAR files are uploaded to the project at the same time the PLP is opened. If you have a **RANGER** series scanner (VUX-1, VUX-120, VUX-240) you will need to convert your RXP files to SDCX.

{% hint style="info" %}
SDCX file conversion is only necessary for systems with a Riegl LiDAR scanner. LiDAR data from any of the Scout, Recon, or AL3 series systems does not require this step.
{% endhint %}

Navigate to Tools->LiDAR->Convert Riegl RXP to SDCX, then add the RXP files from your project folder:

![](/files/bwyNHA69aJAUPyco7U91)

Once you have added all RXP files, click **Process**. Once processing is complete, close the dialogue, save the PLP, and close SpatialExplorer. When you reopen the PLP, you should notice that the LiDAR sessions now reference the SDCX files (rather than the original RXP files):
