I am using ON1 as my photo editor. The application does not include a catalog so all my photo files are are contained in Finder folders. The system works fine but every file included one .xmp file and one ,ON1 file, collectively called sidecar files.
There must be a way to hide these files on a universal basis using Terminal or perhaps a third party app.
Sure would appreciate some help.
