Same problem, same situation.
I'm no Unix guru but I can do quite a bit of rudimentary command line stuff in the terminal so I tried this and they're invisible for now.
1. Open Terminal
2. cd /
3. chflags hidden Cache.db <return>
4. Press the UP arrow on your keyboard - the previous command should pop back up (keep pressing UP to continue through all previous commands you entered).
5. Add -wal to the end of the file name.
6. Press the UP arrow on your keyboard and backspace out the -wal and add -shm. Then press <return>
Alternatively, you can just type chflags hidden at the prompt and drag each file from their Finder window to the terminal window and it will do the typing for you. You'll just have to press <return> after each command.
7. To exit Terminal, just type 'exit' (without the quotes) and hit return. You'll get:
[Process completed]
You can then quit terminal. That's a graceful exit.
I don't know if the system will change the flags back to nohidden (the Unix command that undoes what you did above - just repeat the steps with nohidden and you can do it yourself to any file) but they're gone for now. If they become visible (and they shouldn't) I'll try the phony folder trick.
If you've never messed with terminal, this is a good introduction and this stuff may give you a thrilling experience, and the desire to learn more commands. Anything you learn in terminal will eventually come in handy. Now learn the following commancs: ls mv cp (list files, move files copy files) and you've got a small arsenal of handy stuff. Now try ls -l and you'll really start having fun.
Lastly, I'm still on 10.8.5 on 3 Macs and won't "upgrade" until I see rock-solid stability and compatibility.
I'm a late adopter and proud of it. 25 years as a small-company IT manager and never had any trouble with this philosophy! It was almost three years before I switched the company's 30 Macs from OS 9 to OS 10. Jaguar is when I did the switch - after the 2nd or 3rd version came out.
Thanks for the suggestion
