I did what Roger instructed. I went to Disk Defragmenter and tried to defrag.

here's the message I received

"VOLUME HP_RECOVERY (D) has only 11% free space available. Disk Defragmenter requires at least 15% usuable free space. There is not enough disk space available to properly complete. etc.

Delete some unneeded files on your hard disc (or drive, I forgot)

Now I have no idea what files I have on D. I thought the only hard drive I used was C.

Please tell me what files I have on D and that I don't need, so I can get rid of them.

thanks much.

Obviously I haven't run a disc defrag in quite a while.
