Working with media - Allocated Space

Allocated space is space within the disk which the operating system has already written to (whereismydata.wordpress.com, 2008). Basically this space is already being used for one thing or another. In the image below, we can consider the highlighted area as allocated space

Hope you find this information helpful and please see the other posts in this series for additional information on working with media
