System.io.file.exsists & mapped drive

**jonpanky** · February 5th, 2013, 07:00 AM

Hi,

I'm trying to check if a file exists in a mapped folder.

Code:

               
 If IO.File.Exists(PhysicalLocation) Then
  blnExists = True
 Else
  blnExists = False
End If

Web server 2008 R2
IIS7

For some reason it keeps returning false, it must be a permissions issue on the folder.

Does anyone know which account I should give permission to on the folder so that .net it can access the folder?

I have given IUSR and IIS_IUSRS read/write permissions on the folder and it's still not working

if you just check for file it is not permissions...
Check value of PhysicalLocation ...

In case anyone else has this problem we used UNC instead of mapped drive
