Obviously, there is no error trapping, etc. in this - so you would
want
to add that in a real world scenario.

I shall gives these a shot, but none of them are exactly what I'm looking
for.
I have an app that checks for the existance of a large list of files. The
original technique was to use the DIR function to determine if the file
existed. This is too slow. It's much faster to dupm the directory to a
text file and search that instead.
My gut feeling is that the methods presented so far will be slower then
opening a DOS session and using dir [SourcePath] /s > TargetFile.txt. I was
trying to do this with the SHELL function but without success.

Wow... Maybe something like:
const dirName as string = "c:\whatever"
dim searchFile as streamreader = file.opentext("filelist.txt")
dim searchlist() as string = searchFile.ReadToEnd().Split(Environment.NewLine)
for i as integer = 0 to searchlist.getupperbound(0)
if file.exists(path.combine(dirName, searchlist(i)) Then
' file exists
else
file.doesn't exist
end if
next i
should be fairly easy to modify this into a recursive routine that would
scan an entire directory tree if needs be...

My method would have been somewhat slower - but I don't think by much,
since you are simply running the same command... Of course, you could
just put the redirect on the command line and then call it like this...
with command.StartInfo
.FileName = System.Environment.GetEnvironmentVariable("COMSPEC")
.Arguments = "/c dir /s " & Me.sourceDirectory.Text _
& " > " & outputFile.Text
.CreateNoWindow = True
.UseShellExecute = False
End With
command.Start()
command.WaitForExit()
command.Dispose()
Read in your output file... But personally, I think your going to want
to take a closer look at the System.IO namespace, especially the
Directory, File, and Path classes.

I must be missing an Import statement. It doesn't like the
with Command.StartInfo line, or any of the other command. lines.
