The operation of URL Blocker is based on a method described in several articles on the Internet. In essence, certain URLs can be blocked by properly editing the “hosts” file in the c:\Windows\System32\drivers\etc\ folder. URL Blocker edits the contents of this file in an appropriate manner and it also includes other services.

As the file mentioned above is a system file, editing it requires the program to be run with administrator privileges. The program does not perform any other system-level operations. It is safe to run it as administrator.

When first started, the program saves the contents of the existing “hosts” file as “hosts.urlBlockerSave”. This is important for any possible future restore.

The URLs can be entered in the text box located at the bottom part of the program. After pressing the Add button, there is a syntax check. If the format is appropriate, any “https://” and “http://” parts are removed and the data entered appears in the list. Any amount of data can be entered.

The Restore option restores the state before the program was first started, and the Default option loads the original (after Windows install) value of the “hosts” file. After these operations, the previously set values disappear, so it is practical to create a save first with the Export option.
