Sometimes, stuff gets stuck in Windows trash. Mouse-click trash emptying doesn’t work any more.
If that happens, use the following DOS code in the command line:
rd /s /q C:\RECYCLER
If something’s really stuck in the recyler, you will get the following error message (or equivalent in your operationg system installation language):
Problem - Le processus ne peut pas accéder au fichier car ce fichier est utilisé par un autre processus
Ignore that message. The trash on the desktop, too, will still have the “full” icon but this wull be gone once you right-point it and ask the trash to be emptied.
