Note: For users of Btrieve 6.x and earlier, PSQL can create files in 8.x and 7.
x formats. These newer formats allow for enhancements and new features.
Btrieve 6.x and earlier cannot open PSQL 7.x or 8.x files. However, PSQL v12 can open pre-7.0 files. When PSQL v12 opens pre-7.0 files, it does
not convert the files to the 7.0 or 8.0 formats. Also, you can configure the PSQL to create files using a pre-8.0 format. This may be useful if you want to use newly created pre-V8 files.
You can choose to not to automatically extend PSQL 9.x files or later at 2 GB. To change the segment operation setting access the configuration settings in the PSQL Control Center (PCC) as described in
Configuration Through PCC in
Advanced Operations Guide. From there you can set the
Limit Segment Size to 2 GB option.

Advanced Operations Guide), the new file name includes as much of the original file name as possible and an appropriate file extension, as in the following examples:
