I have a Dell Model Dimension 4550.
I record a lot of radio programmes using Hauppage and store them in my library as WAV files then burn on to CD for later listening.
The total size of my local disk is 60GB but I only have about 130MB free.
This means that I am unable to store any further programmes and the PC operates slower than is required
Is there any way I can increase my capacity without too much trouble?
Any responses would be appreciated preferably in simple language as I am not particularly computer literate so words of one syllable would be good.

many thanks

Here is your model's Tech Guide:

You can add an internal hard drive or get an external drive.

That would be the first choice. If you have no problem using a screw driver I would suggest adding an internal drive.

Anyway that is the first decision to make.
