What does 100 disk usage mean

Disk space is measured in gigabytes (GB), megabytes (MB), kilobytes (KB), and bytes. Disk usage is the amount of storage space used on a computer system.

In general, the larger the number of files stored on a drive, the higher its capacity. For example, a 500 GB hard drive can hold approximately 5,000 songs, but only 1,500 songs can fit onto a 50 MB CD.

Click on the “System Summary” tab and look under the heading “Storage Usage.”
