What is the DXP file format?
Files with the .dxp extension are disc compilation project files created by CDBurnerXP, a free application used for burning CDs and DVDs. The content of a .dxp file is a resource list - all the files and folders that the user intends to save on an optical disc, along with their directory structure and names. Files with the .dxp extension are saved using the XML markup language, so they can be opened and inspected in any text editor.
A .dxp file is a project manifest only - it does not embed the actual file content. If the source files are moved or deleted after saving the project, CDBurnerXP will be unable to burn the disc. The XML structure records disc settings such as volume label, file-system type (ISO 9660 or UDF), and the ordered list of source paths on the local filesystem.
CDBurnerXP supports CD, DVD, and Blu-ray data compilations. The software last saw active development around 2015-2018 but continues to work on Windows 10 and Windows 11. Note that the .dxp extension is also used by TIBCO Spotfire dashboard files - a completely unrelated product - which can cause confusion when sharing files.
Security & safety
RISK: LOWDXP is a passive XML text file and poses no direct execution risk. However, it reveals the full local filesystem paths of the files that were queued, which could be a privacy concern if shared. Do not confuse a CDBurnerXP .dxp with a TIBCO Spotfire .dxp (which may be large binary data) or Altium Designer .dxp - check the file size and content.
Format details
in a nutshell- TIBCO Spotfire Dashboard - TIBCO Spotfire uses .dxp for its business intelligence dashboard files - a completely unrelated enterprise analytics format.
- DXP (Altium Designer Exchange Package) - Altium Designer uses .dxp for PCB/schematic project exchange files - unrelated to disc burning.
Programs that open DXP files

CDBurnerXP
Free File > Open Compilation and select the .dxp file to restore the burn queue; then insert a disc and burn. 
Notepad / any text editor
Built-in Open the .dxp in Notepad or VS Code to read the XML and see which files were in the burn queue - useful if CDBurnerXP is not installed. Technical details
