.RSR File Extension
File TypePoser Model Preview File
What is an RSR file?
Preview image of a 3D model created with Poser, a 3D model rendering and animation program; provides a thumbnail preview image of the model in the Library palette; saved with the same filename as the file it represents, except for the extension.
NOTE: RSR files are only used by the Windows versions of Poser before the Poser Pro Pack. They can be read by the Windows version of Poser 7 and earlier, but are not supported by Poser 8. Newer versions of Poser save preview images in the .PNG format, which is compatible with both Mac and Windows machines.
