Thanks Phil. What exactly does "|4b3a5c|" signify? If I want to use different drive letters etc, how would this appear in a rule? It would be nice to be able to create these myself but I'm not sure how you came up with this! Any info would be appreciated!

can't just create a rule that searches for "K:\" because the rule doesn't work. I think the colon screws it up or something. Someone in this forum once mentioned putting some type of code in for the colon and backslash instead such as creating a rule to look for "K|C3A|" or something like
that,
but all recommendations from that person failed. Does anyone know how I can create a rule to search for "K:\" (can be any drive letter....it's the colon and backslash that are important)?
"|4b3a5c|"
