Lets say you want to lock people out of “C:\Mine”

Just rename by the following DOS command

ren c:\Mine Mine.{21EC2020-3AEA-1069-A2DD-08002B30309D}

This effectively lockst the table from all visitors.  Any attempt to go there will send the visitor to the Control Panel.

To unlock the directory just run the next DOS command

ren c:\Mine.{21EC2020-3AEA-1069-A2DD-08002B30309D} Mine

You can protect your directories this way without having to pay for some directory protection software.
