Checking to see of a folder exists

Hi,

I'm using a DIR command to verify that a folder exists on a local C: drive.
If I need to check a folder on a network drive, can I use the mapped drive
letter or must I supply a UNC path to the DIR command. I don't have the
resources to test this myself.

TIA
 
I've used this before, but it's untested, uncompiled here.

Dim TestStr as string
teststr = ""
on error resume next
teststr = dir("\\your\unc\path\here" & "\nul")
on error goto 0

if teststr = "" then
'not there
else
'is there
end if
 
You should use the path with the server name if distributing to other
users. If you're the only one using it, and you don't change your
drive letters, using the drive letter in the path is fine.

Hi Dave,

I was looking for a solution for checking the existence of a server and
found this post of yours and hoped it helps me, but it doesn't. It returns a
wrong False value if path to be checked consists of only the server name.

My aim is to separate cases of non-existence of a folder:

1. The folder doesn't exist on an existing server.
2. The folder doesn't exist because the server itself doesn't exist (e.g.
its name is mis-spelled).

Any idea?

Regards,
Stefi

Thank you Bob for your reply! It partly helped because it returns True for
any sPath meeting formal criteria (starting with \\) and False for
non-meeting ones but doesn't reflect that server sPath is a really existing
server or not.

Any further idea?

Just pass it the server, no other path, and see

I tried it again with this test macro:

Sub test6()
Dim uncserver As Boolean
Dim teststr As String
' teststr = "\\s00dt002"
teststr = "\s00dt002"
' teststr = "\\xxxxxxxx"

uncserver = False
uncserver = IsUNCPathAServer(teststr)
If uncserver Then
MsgBox teststr & " is there!"
Else
MsgBox teststr & " not there!"
End If
End Sub

"\\s00dt002" is an existing server, "\s00dt002" and "\\xxxxxxxx" are of
course not.

I get " is there!" message for "\\s00dt002" and "\\xxxxxxxx", " not there!"
for "\s00dt002".

What I'd like to achieve is getting
" is there!" message for "\\s00dt002
" not there!" for "\s00dt002" and "\\xxxxxxxx".

What do I do wrong?

Thanks,
Stefi
