The correct location is when the loFile.Length is used, which is an object from FileInfo.

Here is a portion of the code:

            loDirectoryInfo = New DirectoryInfo(cDirectory)

            Try
                loFiles = loDirectoryInfo.GetFiles(cFilter)

                ' Get all the files in the directory
                For Each loFile In loFiles
                    loRow = oDataSet.Tables(0).NewRow

                    loRow("Extension") = loFile.Extension
                    loRow("LastUpdate") = loFile.LastWriteTime
                    loRow("Name") = Trim(loFile.Name)
                    loRow("Size") = loFile.Length

So, the last line is where the problem is. As soon as I have a file name having more than 160 characters, loFile.Length will generate an error.

And, it is not about the loRow("Size") field. I tried to dump loFile.Length into a double variable and it was the same.
