My application supports various files types and all of them use my custom icons assigned to them. Only the files with extension .ini show the icon for a second when I save them and then they return to another icon. The icon used by the system has on the left of the icon text and at the bottom in bigger font it says .ini. The text reflect the content of the file. I have set with file-info to use my application as the default to open the files with this extension,does not help to use the icon. Double click on the file does open it with my application. Is there an application standard to MacOs assigned to those files? I simply can not figure out why only these files will not use my icons. Any ideas?
