How to open ACO file?

The most common problem when using Adobe Photoshop Color Swatch Format is that a specific ACO is not associated with the program. Thus, when you open ACO, the program selection wizard or some other program starts. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the ACO file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Adobe Photoshop

An often overlooked issue is to make sure that Adobe Photoshop is installed on the computer. To do this, enter the name Adobe Photoshop into the system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file ACO with Adobe Photoshop. Below is a list of programs that support the file ACO.

Programs to open ACO file

Remember to download programs supporting ACO files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Adobe Photoshop with ACO files

If the application is or has been freshly installed, but the ACO file still does not use the Adobe Photoshop program, it means no association. It is most convenient to call the context menu with the right mouse button and select Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can set the program to handle this type. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the ACO file with the Adobe Photoshop application.

Step 3. Update Adobe Photoshop to the latest version

The fault may also lie with the Adobe Photoshop program, it is possible that Adobe Photoshop Color Swatch Format requires a newer version of the program. This can be done using the application (if it provides such options) or from the Adobe Systems Incorporated website and install the latest version.

Step 4. Check for the following problems with the ACO file

The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:

The affected file may be 0 KB or smaller than expected. This suggests truncating the ACO file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. If this is not possible, you can use the online scanner. For the best results, we will scan the entire operating system, not just our ACO file. Sometimes virus-infected ACO files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the ACO file. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular ACO file corruption. The easiest way to restore the file is from a backup or by contacting Adobe Systems, but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted ACO files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. While there is usually no problem reading such a file, it may not be possible to save it. It is best to move ACO to a different directory.
This problem usually affects more complex files. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. Sometimes you have to wait for the session to the file ACO to close. Some anti-virus or backup software may occupy the ACO file for a certain period of time. If this does not work either, restart the device.
