Slots directories that I have no control over.

[Ageless]

While doing a complete uninstall of BOINC, I found I have a couple of slots directories on two computers that I cannot get rid of. When trying to delete them manually - even after I have completely uninstalled BOINC and managed to get rid of the rest of the Data directory - I always get the following message: "Can't delete 'filename' or map. Access is denied. Check that your disk isn't full or write protected or that the file is in use at this moment".

In one of the places it's a file that won't be removed. I cannot change its attribute due to permission problems. I cannot assume permission over it either. In the other case it's two maps that I cannot access and see what's in them, nor delete.

Now this may well be a Windows (XP SP3) problem, but I would think that BOINC should at all times have ownership of all files and folders in the Data directory. And since I am a user of the BOINC administrative groups, I should be able to delete the file or folder.

As far as I can see, the slots were used by either Drugdiscovery@…, or Hydrogen@Home. But how can a project take ownership of the slots directories? Isn't that a form of hijacking? And wouldn't that be a security problem?
