To check the total storage used, log on as the administrator on Egnyte's web interface. On the top right hand corner, click on the hamburger menu and look at the Data Usage section.
More detailed information about your data usage is available through Reports.
Under Dashboard, select the "Storage" tab.
Information about storage space, growth, and users' private folder size can be viewed in this section. Egnyte tracks storage per account and does not allow storage size restrictions on individual users.
