Files: Edit Disk Space Allocation (FTP)
Overview
You can modify the amount of disk space allocated to any of the available FTP accounts. Follow the instructions below.
NOTE: Your overall FTP disk quota is limited by the total disk space available for your hosting account. For example: If you have 5000 MB of disk space in your hosting account and set a FTP account's disk quota to 9999 MB, the quota will still be 5000 MB.
