More Information

Steps to Reproduce Problem

NOTE: The ADIR() function returns a 0 if the specified file is not found, or a 1 if it is found.

Type the following in the Command window:

   CREATE TABLE test.dbf (name C(20))
   ?FILE('test.dbf')  && Correctly returns .T.
   ?FILE('test.dbf' + CHR(201))  && Correctly returns .F.
   ?ADIR(x, 'test.dbf' + CHR(201))  && Correctly returns 0
   USE
   RENAME 'test.dbf' TO 'test.dbf,.dbf'
   ?FILE('test.dbf,.dbf')  && Correctly returns .T.
   ?FILE('test.dbf,.dbf' + 'X')  && Correctly returns .F.
   ?ADIR(x, 'test.dbf,.dbf' + 'X') && Incorrectly returns 1

NOTE: In the last line above, the ADIR() function returns a 1, indicating that it found a file with the name "test.dbf,.dbfX".
