The information in this article applies to:

- Microsoft Visual FoxPro for Windows, version 6.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

The File() function documentation states that you can include a path with the
file name to search for a file in a directory or on a drive other than the
current directory or drive. Under certain conditions the File() function can
return .t. even though the file does not exist in the path given in the
parameter.

CAUSE
=====

If the file exists along the Visual FoxPro path, the function returns .t..

RESOLUTION
==========

Use the Adir() function. Supply the file name you are checking for as the second
parameter in the Adir() function. The Adir() function returns 1 if the file is
found.

  nFilesFound=adir(atemp,"C:\temp.txt")
  IF nFilesFound=1
       && Do processing on file
  ELSE
       && File does not exist
  ENDIF
