disk fragmenter will not start

the disk fragmenter wont start, there is enough memory for it, the exact message in the small window that pops up is 'disk fragmenter could not start', any suggestions what could be interferring with it or blocking it. Suggestions gratefully accepted

 

Hello try this

allways run scandisk first,

start you computer in safe mode then defrag.

see if that helps

 

Also make sure you have 15% of free disk space, it needs it to work

 

I had a similar problem when I tried to schedule Defrag to run automatically. It wouldn't work, and the message was the same. But manually starting it works fine.

 

thank you DFW for your reply, yes there was plenty of space, i have been caught short before on that, one suggestion was to run scandisk- checkdisk, and that worked well, now i can defrag
