When you save a selection to a hard disk or a removable disk, Paint Shop Pro saves the selection as a separate file with a .PspSelection extension. You can then load this selection into the current image or another image.
To save a selection file:
Make a selection in the image.
Choose Selections
> Load/Save Selection > Save Selection to Disk to open the
Save Selection to Disk dialog.
The Selection files group box shows selections
files in the default directory for selections. To change the default directory,
or to add another directory, click the Edit Paths
button.
In the File name edit box, type a name for the selection.
Click Save.
