What is an STA File?

How to Open, Edit, & Convert STA Files

A file with the STA file extension is most likely an Adobe Photoshop Match Color Image Statistics file.

Photoshop uses STA files to save image options like luminance, color intensity, and fade, so that the same values can be applied to a different image or layer.

Other Possible Uses for STA Files

Multiple Arcade Machine Emulator (MAME) also uses the STA extension for their MAME Saved State file format.

The emulator uses the format to capture the entire current state of an arcade game that's being imitated through computer software.

When an MAME STA file is created, the emulator stops all the gameplay at that exact moment (basically like pausing the game) and can use the file again to resume the game at that exact same place. So with MAME, the STA file enables an easy way to stop and then resume progress whenever you like.

Some STA files may instead be plain text ABAQUS Status files used by the Abaqus computer-aided engineering software.

How To Open an STA File

Assuming an STA file is an Adobe Photoshop Match Color Image Statistics file, it can be opened (surprise!) with Adobe Photoshop.

While most files can opened in their default program via double-clicking, that won't work with Photoshop STA files. You'll have to open one of those manually instead:

Be sure the image you want the STA file applied to is already open in Photoshop and then go to the Image > Adjustments > Match Color... menu item.

Choose the Load Statistics... button to select the STA file that should be applied to the photo.

Tip: You can build your own Image Statistics file in Photoshop through the same menu - just select the Save Statistics... button instead.

MAME Saved State files that are in the STA file format are used by MAME and Extra M.A.M.E.

in Windows, and can be opened usingĀ MAME OS X in the Mac OS X operating system.

ABAQUS Status files are just text files, so a text editor like Notepad++ or Windows Notepad can open them. The Abaqus software suite from Dassault Systemes is what creates these STA files, so it can be used to open them as well.

If you find that an application on your PC does try to open the STA file but it's the wrong application or if you would rather have another installed program open STA 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 STA File

Of all the different ways STA files are used, the only format that can be converted to a different file type is the text-based ABAQUS Status file. A text editor can save the file to some other text-only format like TXT, HTML, RTF, PDF, etc.

Please understand, however, that converting the STA file to any other format will result in the file not working properly with Abaqus. Since the program uses the STA format, specifically, it likely won't recognize the file if it's saved under a different file extension.
