Windows Explorer additional columns

Sorry, I have a german version of Windows 7 and so my translations are probably not quite correct.
If I ricght-click on the NAME-column of the Windows Explorer I get the option to add FURTHER columns in my DETAIL view. I like the columns DESCRIPTION and RATING.
My question : how can I fill these
columns with data ?
For instance, if I open the PROPERTIES dialog on right-clicking on a .jpg-file and choose DETAILS I can edit the columns there.
But this doesn’t work with .txt,.pdf or (more important) .exe-files.
Are there special programs which do that ? Or can I tweak Windows to let me edit the column data ?
