I want a file on my hard drive in Windows 7 to sync to my public dropbox folder.

I can do this with:

mklink /H "c:\dropbox\Public\test.txt" "c:\data\test.txt"

And the first time after I do this, the file c:\dropbox\Public\test.txt is indeed created, and is available online via http://dl.dropbox.com/u/.../test.txt.

And when I update the file c:\data\test.txt then indeed the file c:\dropbox\Public\test.txt reflects the changes, however: http://dl.dropbox.com/u/.../test.txt does not reflect the changes since DropBox somehow doesn't get the information that that file was changed.

What is a workaround or another solution to this so that any changes in the original file is also reflected in the dropbox URL link?
