Is filepath valid?
 

I have a column that contains a file path with the file at the end - all
contained in the cell. There are about 150 rows. I would like to put
something in column be that says - yes the path and file are truly there or
No it is invalid. I have searched multiple places and have not found
anything pointing to how to do this?

Is filepath valid?
 

I was going to answer as Mike did, but in testing I saw something I'd never
noticed before - if you are looking at a server or shared drive on a
network, referring to one that does not exist with DIR yields an error, not
just an empty string, as Dir usually does. At least I think that's what I'm
seeing. So here's my function:

Function valid_path_and_file(path_and_file As String) As Boolean
Dim tester As String
On Error Resume Next
tester = Dir(path_and_file, vbDirectory)
If Err.Description = "" Then 'If Server5 and SHARE exist
If tester < "" Then
valid_path_and_file = True
End If
End If
On Error GoTo 0
End Function


I called it with this. Again if Server5 or SHARE do not exist, Dir errored
in my test, but the function above did not:

Sub test()
Debug.Print valid_path_and_file("\\Server5\SHARE\GENERAL\test. doc")
End Sub

hth,

This seems to work well:

Public Function bFileExists(ByVal sFile As String) As Boolean

Dim lAttr As Long

On Error Resume Next
lAttr = GetAttr(sFile)
bFileExists = (Err.Number = 0) And ((lAttr And vbDirectory) = 0)
On Error GoTo 0

End Function

This worked GREAT - thank you.

You need a function. Open VB editor (ALT + F11) insert a new module and paste
this code in:

Public Function Filethere(strFullPath As String) As Boolean
If Not Dir(strFullPath, vbDirectory) = vbNullString Then Filethere = True
End Function

in b1 next to your filepath in a1 type =filethere(a1)
drag down as required.
It will return true if the path is valid or false.

Will that do?

I used the above but appreciate this as it will help me when I move the
information over to the shared network from my laptop.

Personally, I would go with a non-Dir solution.
Using Dir sets the CurDir to that location. Whilst not a major problem, it
may impact your code in unexpected ways; calling GetOpenFilename will then
point to that last location, which is probably meaningless to the user.

NickHK,

I didn't know that. How would you do it?

Doug,
One way is with GetAttr(), as posted by RBS in this thread.
Dir also places a <lock on that folder, so it cannot be deleted, with e.g.
RmDir.
