N360, Cannot delete back up files

Hello,

N360 filled up hard drive.

I cannot delete files.

When I check the upper box to select all the computer freezes up.

Windows XP SP3, 233G Hard drive.

Help!

 

Also on my laptop Gateway NV55, windows 7, 500G hard drive.

It is taking along time to delete files, since last night only 3000 files deleted out of 48000 deleted.

How can I make this faster?

 

What settings should I use to keep N360 from taking over hard drive?
