Here we are:

Windows XP:

For Web sites: %APPDATA%\Macromedia\Flash Player\#SharedObjects\<random 
code>\<domain>\<path - maybe°>\<object name>.sol

For AIR Applications: %APPDATA%\<AIR Application Reverse Domain 
Name>\Local Store\#SharedObjects\<flash filename>.swf\<object name>.sol

Windows Vista and later:

For Web sites: %APPDATA%\Roaming\Macromedia\Flash 
Player\#SharedObjects\<random code>\<domain>\<path - maybe°>\<object 
name>.sol

For AIR Applications: unknown, likely similar to the above

Mac OS X:

For Web sites: ~/Library/Preferences/Macromedia/Flash 
Player/#SharedObjects/<random code>/<domain>/<path - maybe°>/<object 
name>.sol and ~/Library/Preferences/Macromedia/Flash 
Player/macromedia.com/support/flashplayer/sys/<object name>.sol

For AIR Applications: ~/Library/Preferences/<AIR Application Name>/Local 
Store/#SharedObjects/<flash filename>.swf/<object name>.sol

Linux/Unix:
~/.macromedia/Flash_Player/#SharedObjects/<random id>/<domain>/<path - 
maybe°>/<flash filename>.swf/<object name>.sol

° - Flash player can save the file in any path specified by the SWF 
developer, relative to the current domain.
