Choose between two options:

Level1Remove -- slow down access to the zip by forcing users to save them to the hard drive before opening them.

2. Under that key, add a new string value named Level1Remove.

.zip;.mdb;.url

would force you to save Zip file type and unblock Microsoft Access files and Internet shortcuts.

* Level1Add
