This may not be the best place to ask a Windows question but I bet someone knows. I recently updated from Vista to Windows 7 Ultimate and am having a hard time updating one particular file. As I have done for years, I have a C:\Data folder which contains various subfolders containing data from Quicken, TurboTax, etc. It also contains a file named pswd.txt which I cannot seem to update. It is the only file at the root level of C:\Data. Even when I move it to a subfolder I get an "Access is Denied" error. Other files under C:\Data are updated with no problem.

What do I need to do? Can I just turn off UAC like in Vista?
