Al abrir Lightroom se crean archivos temporales en el escritorio

Hi Enriquem,

Sorry to hear that .dat files are created whenever you launch Lightroom, could you please let us know the exact version of Lightroom you're working on?

.dat files are the Camera Raw Cache files. It's a temporary cache which speeds up access to photos in the Develop module. You can set the size and location in Lightroom's Preferences dialog > File Handling tab, and there's a purge button there too, which will delete them.

Regards,
Sahil
