How can I convert my Paradox 3.5 DOS files to work in COREL's Office 7 Paradox 7 version? I can get the files to read and can make changes to them, but when I try to "Query" the file I get "Invalid File Name" error message. I have tried restructuring the file and the Restructure Dialog box says the file has been converted to version 7, but it still will not query.  Are there any patches of fixes for this problem? Thank you.

Try this with one of your tables, and see if it fixes the problem:

Keywords: Paradox,Windows,Restructure,3.5
Question: How can I format my old Paradox DOS 3.5 table into a Paradox For
Windows table format?

Answer: Since there is not a restructure option to accomplish this task,
there
is a workaround.  The following steps demonstrate this technique:

1)  Choose File | Utilities | Restructure from the Main menu.  Type in the
name
of your Paradox DOS 3.5 table.

2)  Add a new field to the end of the table structure.  The field type must
be
one of the following BLOb (Binary Large Objects) types: Memo, Formatted
Memo, Graphic, or OLE.

3)  Save the new table structure.  Paradox automatically detects the new
field
and its field type and converts the table structure to one compatible
with Paradox For Windows.

4)  Choose File | Utilities | Restructure from the Main menu.  Type in the
name
of your Paradox DOS 3.5 table.

5)  Delete the newly added BLOb field.  Save the table.

6) then, try your query

Thank you for your answer. I tried these tricks before I asked my question, but I was still unable to query the files, even when the Restructure Dialog box said the file was in Paradox 7 format.

I have found out that the error problem arises because Paradox was originally written for Win 95 with the FAT 16 system.  I have the newer version that uses the FAT 32 file allocation table. The problem was that when I querried the file it gave an invalid file error because it could not locate the 32 bit file in the 16 bit FAT. The fix is to download the file FAT32.EXE from the Borland ftp site at: ftp://ftp.corel.com/pub/paradox/bde. This is a self extracting file. double click on the file and then copy the new file idapi32.dll to your Corel/Shared/idap3 directory.  Check to be sure if you have any other copies of this old dll dated around February 1996.  You must update all copies of the file.  After updating, I could query all of my Paradox files and run the Experts. The old FAT16 could also not find the experts.  This should fix the FAT incompatibility problem, and physically converting the DOS files to Paradox 7 is not necessary.
