What is an ASE File?

How to Open, Edit, & Convert ASE Files

A file with the ASE file extension is an Adobe Swatch Exchange file used for saving a collection of colors accessed through the Swatches palette of some Adobe products like Photoshop.

Autodesk software can export files to the ASE format. They're used in these programs as plain text files that store information about 2D and 3D scenes. They're similar to Autodesk's ASC format but can include more information on things like shapes and points.

Other ASE files may be Velvet Studio Sample files, which are audio files used for storing instrument sounds.

How To Open an ASE File

ASE files can be opened with Adobe's Photoshop, Illustrator, InDesign, Fireworks, and InCopy software. This is done through the Swatches palette, which you can open through the Window > Swatches menu.

Select the small menu button to the top right of the palette and then click Load Swatches.... It's called Open Swatch Library... in Illustrator, and Add Swatches... in Fireworks.

Note: If you can't find the ASE file, be sure that the "Files of type:" option is set to Swatch Exchange (*.ASE), else you may be filtering the results for other files by mistake, like ACO or ACT files.

You can author Adobe Swatch Exchange files at Adobe Color CC, which you can then download in ASE format.

Autodesk ASCII Scene Export files can be opened with Autodesk's AutoCAD and 3ds Max software.

Since they're text files, any text editor can be used to read the file, like Notepad++.

Velvet Studio is used to open ASE files that are Velvet Studio Sample files.

If you find that an application on your PC does try to open the ASE file but it's the wrong application or if you would rather have another installed program open ASE files, see my How To Change the Default Program for a Specific File Extension guide for making that change in Windows.

How To Convert an ASE File

As you can see above, there are a few different uses for ASE files. However, I don't think there are any file converters or programs other than those listed above that can use these types of ASE files.

If you're looking for a way to convert an Adobe Swatch Exchange file to a text format to see the colors it contains, this post at Adobe Community may be helpful.

You might be able to use the Autodesk software I mentioned above to save an Autodesk ASCII Scene Export file to a new format, but I haven't tried this myself to have any more detail. Look for a File > Save As menu or some sort of Export option - you might be able to convert the ASE file that way.
