no client-side code to check if a file path exists?

[Matt]

<input type="file" size=50"> will produce the browse button
and browse text box.

The user can either select the file from browse button,
or enter a path in browse text box manually. My question is if
there are any client-side code to check if the path exists
in this case? My understanding is that no client-side
solution to this problem.

please advise. thanks!!

No, assuming you mean javascript code.

Correct. Javascript does not have access to the local file system, or any
file system for that matter.
