Macro 1: Check the Current Default Directory
 Sub MAIN a$ = Files$(&quot;TEST.TXT&quot;) If a$ <> &quot;&quot; Then MsgBox &quot;File Exists&quot;, a$  End Sub NOTE: The Files$ command returns a null string (&quot;&quot;) if the specified file is not found.

Macro 2: Change Current Directory
  Sub MAIN ChDir &quot;C:\WinWord&quot; a$ = Files$(&quot;newmacro.doc&quot;) If a$ = &quot;NEWMACRO.DOC&quot; Then MsgBox &quot;File Exists&quot;, a$     ' The above file name within the If statement must be uppercase. End Sub NOTE: Word 6 for the Macintosh users should be sure to include a valid Macintosh path, for example:

"Mac HD:Microsoft Word 6:Test Document" The following macro tests whether the &quot;Test1.doc&quot; file exists in the current directory before using the WordBasic Kill command to delete the file named Test1.doc.

  Sub MAIN a$ = Files$(&quot;TEST1.DOC&quot;) If a$ <> &quot;&quot; Then Kill a$  End Sub
