How do we get User Profile picture

• We observe that User Profile Picture are stored under “\Portals\0\Users” in folder structure
• The Folder structure goes like this initially ( when user ID in single or two digit)
o UserID – 1 in Database
o Folder structure – 001\01\1
• What happens when the User ID goes above 100 or 1000 i.e. how is the folder structure formed.
