Where do Flash files get stored in Lion?

Hold down the option key and select Go > Library in the Finder.

In Finder, ⌘F, Search: (This Mac), then select ➕, then File Extention, enter sol:

Spotlight searches from the Finder don't show hidden files, or files in hidden folders, and may be limited in other ways so as not to confuse inexperienced users. You'd have to use either a third-party Spotlight interface or the "mdfind" shell command.

Use DevonTechnologies' EasyFind; it finds everything on your system regardless of where it is or whether its hidden or not. It's also free... 🙂

You can expand the search for system and hidden files (option-click ➕):

And if you're comfortable in Terminal, use find:

to seach your user account:

find ~ -iname '*.sol'

to search HD:

find / -iname '*.sol' 2>/dev/null

But first, try:

In Finder, ⇧⌘G, and enter "~/Library/Preferences/Macromedia/Flash Player/macromedia.com/"

Then in the Finder Search window, enter: .sol
