Volumes become fragmented as users create and delete files and folders, install new software, or download files from the Internet. Computers typically save files in the first contiguous free space that is large enough for the file. If a large enough free space is not available, the computer saves as much of the file as possible in the largest available space and then saves the remaining data in the next available free space, and so on.
After a large portion of a volume has been used for file and folder storage, most of the new files are saved in pieces across the volume. When you delete files, the empty spaces left behind fill in randomly as you store new ones.
The more fragmented the volume is, the slower the computer's file input/output performance will be.
