Flexible File and Folder Organizing Tool

[bjk]

What I would like to do:

Save files/folders physically only once but assigning them to different multiple (logical) folders that will represent ideas/projects and so on.

I know this could be achieved by manually creating links from the desired folders to the original files but I'm searching for something more comfortable and easier. Maybe tagging files? Or a tool from within I could click on the "physical file" and then assign/create one or more "logical" folders.

Does somebody knows of such a tool? Thank you very much in advance!

You can create a virtual folder in Windows by using junction points (called reparse points in Vista). A few links -

simple cmd line app - http://www.microsoft.com/technet/sysinternals/FileAndDisk/Junction.mspx

e.g. if you have c:\docs\taxes, you can do
junction c:\imp c:\docs\taxes
junction c:\tax c:\docs\taxes

and both will point to the same physical folder.

For tagging you can take a look at 2 promising apps - taggtool and tag2find.

Don't get me started again on what WinFS could and should've been
