Step 1
By default, alfresco disabled the quota usage calculation
globally. So we need to enable this. Open repository.properties file.
Step 2
Identify the below statement.
system.usages.enabled=false
Step 3
Change the system usage enabled to true.
system.usages.enabled=true
Step 4
Restart tomcat.
Step 5
Create a new user and allocate some quota.
Step 6
Login as the created user and upload some contents in a
document library.
Step 7
Go to Admin tools-->Users-->Find the user. Here you can
see the user's quota and used storage details.
Please note:
If you're not set the system.usage.enabled to true then the Usage will be zero.
