What Is a PSF File?
A file with the PSF file extension is most likely an Adobe Photoshop Proof Settings file. These kinds of files store specific color preferences so that you can see how an image will look before you print it. A PhotoStudio file is an image format that uses this same file extension. They can contain text, layers, and shapes. Other programs might use the PSDF file extension, too, like as a GPS Prediction Support file, AutoCAD PostScript Patterns file, Portable Sound file, PID Script file, or an HP-UX Product Specification file.
How to Open a PSF File
Adobe Photoshop Proof Settings files can be opened with Adobe Photoshop through the View > Proof Setup > Custom menu option. Select Load to import the file. The free XnView program will open PSF files that are associated with ArcSoft’s PhotoStudio. The PhotoStudio program can, of course, use them as well, but know that it’s been discontinued by ArcSoft and is therefore no longer supported. Although this method doesn’t apply to most other file types, you can instead just rename the PhotoStudio file’s extension to JPG and then open it in Photoshop (and maybe other image editors/viewers). Here’s some information on the other programs that use PSF files:
GPS Prediction Support file: AGI’s Systems Tool Kit (STK) or LinQuest’s GPS Interference and Navigation Tool (GIANT) AutoCAD PostScript Patterns file: Autodesk’s AutoCAD Portable Sound file: XMPlay (it requires the Highly Experimental plugin) and Audio Overload PID Script file: Palmer Performance Engineering’s PCMSCAN HP-UX Product Specification file: HP’s Software Distributor (SD) SPI Proxy Output file: SPI Dynamics WebInspect Toolkit
How to Convert a PSF File
As you can see from above, there are lots of possible sources for your file. It’s important to first recognize what your particular file is used for before you can understand how to convert it. An Adobe settings file, for example, probably doesn’t need to be nor can be converted into any other usable format. A PhotoStudio file, though, is an image file that can be converted to JPG and other similar formats using XnView. You should follow the same process for the other types of PSF files listed above. You can open the file in the program that created it and then try to export or save the file to some other format.
Still Can’t Open It?
If your file doesn’t open after trying all the suggestions above, there’s a good chance you’re misreading the file extension. This can happen rather easily because so many file extensions share the same few letters, which can make you mistake another extension for this one. PFS is one example where all the same letters are in the PSF file extension. However, this one is used by PhotoFiltre Studio for Saved Selection files. Another is PSS which is used for PlayStation 2 Game Video files, Picture and Sound Show files, RoboHelp HTML Project Data files, and more.
