Jean, Thank you.  It's slow but it works. dir("C:/", pattern="plotrix.pdf", 
full.names=T, ignore.case=T, recursive=T)   Does anyone have a faster way? If 
it helps using:      shell.exec("search-ms://query=plotrix.pdf")    utilizes 
windows's search bar to find the file (this is quick), however it opens a 
screen that finds the file rather than providing me with the search path.  For 
a look at what that looks like on a windows machine click here:

I'm thinking there's a way to use this method to extract the path even faster 
than dir(). TylerTo: tyler_rin...@hotmail.com

Try the dir() function.



?dir



# for example

dir("c:/", pattern="foo.pdf",
full.names=T, ignore.case=T, recursive=T)
