RE: TZF - "Default Directory" & reindexing - Clarification of Issue

Guys,
 
Thanks for the comments but you have not addressed my problem
 
 
I have a DBF with an associated MDX  (eg.   fred.dbf  & fred.MDX )  -
All working OK
 
I set Active = false
 
Delete all of the "fred" files
 
I utilise a FileOpenDialog to allow the user to select the new version
of the DBF (it is in a ZIP file & must be UNZIPed first)
 
I REPLACE the DBF file with a new version of the DBF (MDX NOT copied)
 
--- I do NOT change the DBFfilename property of the TTzDBF component, it
still points at the correct file (albeit a new version)
 
I set the CreateIndex property to  ciAlways
 
When I set Active = true,  TOPAZ tries to recreate the MDX - (as
expected)
------------------------------------------------------------------------
-----------------------------------------------------
My problem is that
            If FileOpenDialog browses to the hard disk to find the new
DBF file - ALL is OK
 
            If FileOpenDialog browses to a floppy or CD for the new DBF
file - I get an exception error (insufficient disk space)
 
The problem stems from the FileOpenDialog component changing the
operating system "current directory". However, the problem is a TOPAZ
issue & NOT a FileOpenDialog one.  
 
Note the problem only occurs when the operating system "current
directory" is changed to a floppy or a CD.
( I haven't tested this but I would assume that the problem may also
occur if the selected directory was READ ONLY to the logged in user)
 
Inserting a ChDir to a harddisk based directory just prior to the
Active=true overcomes the problem. 
While I could use this method to work around the problem, it would be
better if TOPAZ automatically used the operating system TEMP folder for
temporary files. 
 
Is there any way to tell TOPAZ to use the "current TEMP folder" during
the index rebuild rather than it using the "current default directory" 
   OR 
do I have to go through the TOPAZ code and update it manually ?
