Windows – Using Dropbox as a backup service

I can't understand exactly what you're asking, but if you want to have files show up in the Dropbox Public folder and also be somewhere else in the filesystem, it looks like the only option for now is hard links (on *nix operating systems, including OS X):

ln /users/cs/python/codes/1.py ~/Dropbox/Public/

That will create a 1.py file in ~/Dropbox/Public which will be another link to the same file on the filesystem, though it will look like another file. This means you can access the file the same way, and any changes you make to one will be the same with the other (since they're accessing the same location on disk). You can later delete the link in the ~/Dropbox/Public folder, and the other one will still work. Take note: if you delete one of the links and recreate the file there, they will no longer be pointing to the same location on disk.

You can take a look at this post from the Dropbox forums: http://forums.dropbox.com/topic.php?id=9018

Previous poster was close, but it is stored in the host.db file. Sample path from my Win7 machine:

C:\Users\[user name]\AppData\Roaming\Dropbox\host.db

For testing, you can try out this online tool to see if you can successfully decode the base64 string: http://www.opinionatedgeek.com/dotnet/tools/base64decode/
