Property Value
Type: System. . :: . .Boolean
true if the file exists; false if the file does not exist or if the file is a directory.
Remarks
When first called, FileInfo calls Refresh and caches information about the file. On subsequent calls, you must call Refresh to get the latest copy of the information.
The Exists property returns false if any error occurs while trying to determine if the specified file exists. This can occur in situations that raise exceptions such as passing a file name with invalid characters or too many characters, a failing or missing disk, or if the caller does not have permission to read the file.
