Where html filesystem save files ? How to get them?

Where does html5 filesystem sto开发者_开发百科re the files and folders, and can i use them in my hard drive, or somehow. For example can i use these files in my filesystem from other pc ?

When testing using Chrome Canary on my Mac it stores the contents of the file here:

~/Library/Application\ Support/Google/Chrome\ Canary/Default/File\ System/002/t/00/00000000

The 002 part seems to update per "app" and I'm guessing the 00/0000000 part is the "directory/file". Then the meta data, like directory name and file name and other information is stored in this directory:

~/Library/Application\ Support/Google/Chrome\ Canary/Default/File\ System/002/t/Paths
