.ASV File Extension

An ASV file is an autosave file created by MathWorks MATLAB, a mathematical analysis and computation program. It contains an automatically saved version of a MATLAB source code file, better known as an .M file. By default, ASV files are stored in the same location as the M files from which they are created.

MATLAB includes an Editor/Debugger that researchers, developers, and engineers use to create M files. If you edit an M file in the MATLAB Editor/Debugger and do not save your edits within the span of five minutes, MATLAB creates an autosaved version of your edited file. That version is saved with the .asv file extension. If MATLAB quits unexpectedly while you are editing an M file, you can open the corresponding ASV file to keep working from the most recently autosaved version of your file.

If you want to adjust how MATLAB creates ASV files, you can do so by opening the program's Preferences menu and selecting Editor/Debugger → Autosave. From this menu, you can specify how often MATLAB autosaves files, what extension MATLAB assigns to autosaved files, and where autosaves are stored.

NOTE: On Linux and other Unix platforms, MATLAB assigns the .m~ extension to autosaves.

You can open an ASV file with the MathWorks MATLAB Editor/Debugger just as you would any M file. If you need a reminder of where your ASV files are stored, open the MATLAB Preferences menu (File → Preferences) and select Editor/Debugger → Autosave to view the location in which MATLAB stores autosaves.

File created by Finale, a music note creation application for playing instruments, vocals, etc.; replaced by the .ASVX file, which was released in Finale 2014; contains backup data for .MUS files similarly to .BAK files; created when MUS files are auto-saved by Finale.

To create a ASV file:

1. You must first enable the backup creation option.
2. Select Finale [version] → Preferences....
3. Select "Save and Print" in the list on the left of the "Preferences" window, check the "Auto Save File(s) Every __ Minutes" checkbox, fill in the amount of minutes, and click OK.
4. Now when your MUS files are auto-saved, a corresponding ASV file will automatically be created.

Color settings file used by Adobe Photoshop, a program used to create and edit raster graphics; contains color adjustment settings for cyan, magenta, yellow, and black (CMYK) values of different colors, which are on a scale from -100% to +100%); also contains the selective color method, which is either relative or absolute; used for saving color adjustment presets that can be applied to multiple images.

The Selective Color window can be accessed in Photoshop by selecting Image → Adjustments → Selective Color....
