If you need to edit the PQO file, one of the safest methods is to download and install the software dedicated to working with PQO files. There are many tools known as PQO Online Editors, but it is not certain that they operate in a way that keeps the data contained in the file safe.
Remember, that not all of the mentioned programs will allow you to edit the PQO file. Additional information about the PQO file extension can be found here.
This is the best way. Choose one of the programs that support the PQO file extension, open your file and check the editing options. It's safest to download the software from the developer's website. Links to the websites of software producers can be found on the software subpages. Below you will find some examples of software programs that support the PQO file (so it is very possible that they can edit files in PQO format).
All available programs supporting the PQO file
Most of the file formats are simply text format saved under a different extension - so you can open them e.g. with Windows Notepad But beware - making manual changes to the PQO file or another may result in its damage. When you save the changes, you may no longer open the PQO file. By far the safest way is to use file editing programs that works with the PQO extension.
It can definitely be said that any of the list of programs that support the PQO extension should be able to edit the PQO file. However, if for some reason you did not find this option, you can try using tools prepared by external websites. Verified websites with the option to edit the file in the PQO format below.
