A PSR file is a special file with the extension PSR created by Sybase WorkSpace. PSR stands for Powersoft report.
Windows and PSR files
When Sybase WorkSpace is installed, the PSR file type is registered
with Windows.
A PSR file contains a report definition (source and object) as well as the data contained in the report when the PSR file was created.
You can use a PSR file to save a complete report (report design and data). This can be especially important if you need to keep a snapshot of data taken against a database that changes frequently.
