One can free disk space on the computer by following ways:
(a) There should be at least 200-500 MB of free hard drive space on your system. Non-availability of free space slows the functioning of the computer. To check the amount of disk space available, Open the Windows Explorer Application and click on My Computer. This will show the different hard disk partitions such as C, and D.
To check the amount of disk space available on the C drive, highlight the C drive and right click to get a pop-up menu as shown below:

Select the Properties option from this pop-up Menu. Choose ‘General’ Tab of this application. The screenshot in shows the available Free Space on the C Disk, shown by the purple pinkish coloured area in the Pie chart (here 1.91 GB)

Once the Disk Cleanup is complete, the Disk Cleanup dialog box opens . Click on Clean up system files button. This will delete any unnecessary system-related files from the local disk.

Delete Unused Files and Programs

Empty Your Recycle Bin
This can be done by right-clicking on the Recycle Bin icon (usually on the desktop), and then selecting Empty Recycle Bin.

On the bottom left corner of this screen, click on the link Internet Options. This opens the Internet Properties dialog box .
