    JbTecWiz Support Centre -- generated fix script

    Fault : Users cannot save to a share that has plenty of free space
    Fix   : Find the file screen blocking the type
    Source: https://jbtecwiz.com/support/srv-sto-fsrm-quota

    Run as     : Elevated PowerShell
    Expect     : 25 minutes
    Risk       : medium
    Reversible : yes

    WHEN THIS IS THE RIGHT FIX
    Certain file types are refused.

    HOW TO UNDO IT
    Remove-FsrmFileScreenException reverses the exception.

    This script walks the fix one step at a time and asks before each
    one. Steps with no command are things you do yourself -- it prints
    those and waits. Run with -DryRun to print without executing.
