Question Maximum numbers of subdomain in a directory

[Generalomosco]

I'm building a project on plesk where each will be able to create subdomain e.g like.

SubdomainDir/user1App1/user1app1.maindomain.com

SubdomainDir/user2App1/user2app1.maindomain.com

SubdomainDir/user3App1/user3app1.maindomain.com


So, I'm curious to know the maximum number of subdomains SubdomainDir directory can handle.
