Disk space is the amount of data allocated the a specific client. For instance, if a client is allocated 2 GB (2000 MB) of disk space, then he or she could store up to 2000 1 MB pictures on that server.
When calculating disk space usage, it is usually the combination of all the files saved on the server, plus databases and email space.
If a client exceeds their disk space limit, the server will not allow them to upload any additional files.
