I need to find the filepath to the Directory Opus icon for another program. I don't think it wants the .exe file. Also, is there a way to migrate all the outside icons used that I have imported specifically into directory opus so that I don't keep getting happy faces if I move an image or folder it is using?
The icon is inside the main dopus.exe. All/most programs that can work with icons should be able to load it if given the exe path. (If it needs an icon index as well, just give 0 / zero.)
If it's just a handful of loose icons, you could copy them to /dopusdata/User Data and point your toolbars to use those copies. They will then be included in Opus config backups.
If there a lot of icons, making an Icon Set may be worthwhile.
