Working with PSR files
A PSR file is a special file with the extension PSR created by
PowerBuilder, InfoMaker, or DataWindow Designer.
Windows and PSR files
When PowerBuilder is installed, the PSR file type is
registered with Windows.
A PSR file contains a DataWindow definition (source and object)
as well as the data contained in the DataWindow object when the PSR
file was created.

About reports
A report is the same as a nonupdatable DataWindow object. For
more information, see Reports versus
DataWindow objects.
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.
PowerBuilder creates a PSR file when you save data in the
Powersoft report file format. See Saving data in an external
file. PSR files are used primarily by InfoMaker, a reporting
tool. When an InfoMaker user opens a PSR file, InfoMaker displays the
report in the Report painter. If InfoMaker is not already running,
opening a PSR file automatically starts InfoMaker.
To open a PSR file in PowerBuilder, open any DataWindow object,
then select File>Open File and select the PSR file.
