FileNotFoundException on file that exists!

[C# Programming]

Hi, I am running this code:


string fullFilename = "\\\\server\\share\\DL_JP_462153474_461535959_attest.JPG.pdf";
byte[] bytes = File.ReadAllBytes(fullFilename);

and get this exception:

FileNotFoundException
"Could not find file '\\\\server\\share\\DL_JP_462153474_461535959_attest.JPG.pdf'."


The only problem is that the file does actually exist! Also, it works on files with shorter filenames in the same folder. For example:
\\\\server\\share\\DL_JP_448856461_461530268_462153469.pdf
Does anyone know what this is all about? http://www.barakasoft.com/script/Forums/Images/smiley_confused.gif
