What Is a CXF File?

How to Open, Edit, & Convert CXF Files

A file with the CXF file extension is probably a Picasa Collage file. They're created by the Picasa photo editor and organizer program when a collage is built and then saved with the image files. The CXF file retains the paths and positions of the photos used in the collage.

Chemical Abstracts Exchange Format files that store molecular data use the CXF file extension as well.

Other CXF files may be Cuttlefish Extended Format files, Coordinates Export Format files, or Color Exchange Format files.

How to Open a CXF File

Picasa Collage format CXF files can be opened with Google's Picasa. This type of CXF file is actually just a text file, so any text editor can open it, too, if you need to see the image paths and other things that are stored within the file itself.

Picasa is no longer available from Google, but the link above is still a valid way to download it if you need the last released version in order to open and use the CXF file. There's a Mac version of Picasa here.

If your CXF file is a Chemical Abstracts Exchange Format file, CAS SciFinder and STN Express can open it.

Some CXF files store values for a graph used with the Cuttlefish network visualization tool, in which case that program is used to open them.

Use CXeditor if you need to open a CXF file that's a Coordinates Export Format file.

If you think your CXF file is a Color Exchange Format file, you can read more about them at X-Rite. Files in this format are XML based files that store things like color measurements. You can open one with any text editor or XML viewer; Notepad++ is one popular example.

If you find that an application on your PC does try to open the SRF file but it's the wrong application or if you would rather have another installed program open SRF files you can change the default program for a specific file extension.

How to Convert a CXF File

We have no doubt you could convert a Picasa Collage file to another text-based format if you really wanted to, but we can't imagine a reason to do so. The CXF file explains how the collage should appear in the Picasa program, so changing it to any other format would render the collage unusable.

We haven't tested it, but we're sure that a program like CAS SciFinder or STN Express can export a CXF file to a different format.

The same goes for Cuttlefish—most programs have an Export or Save as menu item that can be used to save the file to a different format.

CXeditor, linked above, can export a Coordinates Export Format CXF file to SVG, KML, EMF, Adobe Illustrator file (AI), or XAML.

If your CXF file is a Color Exchange Format file, you can definitely save the XML-based file to another text format with Notepad++ or some other text editor, but changing the format doesn't seem helpful here.

Still Can't Open the File?

CXF files look awfully similar to files that have the XCF, CXD, CVX, or CFX extensions, but they have nothing to do with one another.

If you double-check the file extension on your file and find that it doesn't actually read as .CXF, research the file extension you do see so that you can find more information on the format it's in and the program(s) that can open it.
