Question

What used to work for me, when I would check if File.Exists now returns a false.

We recently updated to the 4.0 — and now any files within my personal User folder return FALSE for File.Exists.

Anyone experience this or know of the issue?

(For example – (File.Exists(“C:\Users\Public\test.txt”)) will equal TRUE but (File.Exists(“C:\Users\peronalFolder.domain\test.txt”)) always comes back FALSE)

Thanks.

It is highly unlikely that File.Exists changed. It is more likely that your environment changed. I would recommend looking into your App Pool settings (if relevant) as @Jesse mentioned.

You can attempt to identify if it is a .NET issue or an environmental issue by using the following powershell script as a unit test for file access:

$SourceFile = "c:\foo\Test.txt";

if ([System.IO.File]::Exists($SourceFile))  {
   "Source File exists"
}
else {
   "Source file ($Sourcefile) does not exist."
}
