Note that many of these programs are more than 20 years old and were written for 16-bit systems; they require extensive editing to be compatible with current hardware. The testing programs, however, are much more recent and run without change on both 32-bit and 64-bit Windows systems.
- BTRVH.ZIP (2,918 bytes) is the Btrieve.H header file required in order to compile the DATASAVE application.
- DATASAVE.ZIP (17,861 bytes) is the data recovery utility described in the Winter 1996 issue of Btrieve Developer’s Journal. Note that the required header file for this program is in BTRVH.ZIP listed above. Also note that these files were written for 16-bit systems and the programs will require significant change to work with Windows versions newer than XP, due to lack of 16-bit compatibility in the newer versions.
- DSAVE3A.ZIP (13,164 bytes) is a modified version of the data recovery utility described in the Winter 1996 issue of Btrieve Developer’s Journal. The modification added progress reporting, and corrected a problem that sometimes appeared when recovering compressed variable-length files. This file includes a text description of how to use the program.
- DEVLOD7.ZIP (46,835 bytes) contains the latest version of DEVLOD from Undocumented DOS, 2nd Edition, updated to work with Windows 95’s DOS version. It also contains extended discussion of a number of problems with the DEVLOD concept. Needs DVSUPORT.ZIP to compile.
- DVSUPORT.ZIP (8,708 bytes) provides UNDOCDOS.H and other support files required for compiling the DEVLOD program.
Testing Programs and Instructions
- TESTER.ZIP (285,764 bytes) contains a program, FileTest, that exhaustively tests any Btrieve/Pervasive file (or files; it permits multiple selection) for damage. It’s totally free for use.
- NEWTEST.ZIP (201,028 bytes) contains a revised version of FileTest that handles files larger than 2 GB in size.
- FILETEST.PDF (106,223 bytes) contains documentation for FileTest as provided in both programs. This file requires a PDF reader to view; most systems today include such a viewer by default.
