Disk space is the amount of data allocated to a specific client. For instance, if a client is allocated 1GB (1,024MB) of disk space, then he or she could store up to 1,024 MB data 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.
