I've been using SymbolicLinker for years, maybe since it first appeared (before 10.6, anyway). I'm not a Unix geek, but prefer symbolic links for their spatial economy – they're only a few K in size (actually only a few bytes, but take up the minimum 4K file size in the file system), while standard MacOS aliases always include a copy of the original's icon (even with folders), making them over a megabyte in size. Aliases are more robust, usually remembering the link even if the original is moved, but I find symbolic links work fine in most cases.
So, thanks for the Service, and for the update – I spent a couple hours last night struggling with some 8,400 symbolic links on the Desktop, and was nervous about using SymbolicLinker again, so came here and found there was an update to address just that problem. Don't know why it happened then, as I've been using v.2.1 just fine for several months. Anyway, works fine again now, in El Capitan 10.11.6.
