1. Create a master folder per category according to how YOU categorize things in your mind.
2. Create subfolders in that one, according to the subcategores YOU think with.
3. Make sure that all these folders, masters and subfolders, are under ONE main folder whose name you easily remember.
Then, as has been said in this thread, you only have ONE folder to backup and copy as a command, #3. Because, when copying 'it', you're copying all the other folders you made in #1 and #2.
Microsoft developed 'My Documents' to do that job, but in Win7 and later, it's confusing to find it. So if you'll rename 'My Documents' to the #3 name you'll remember, it will be easier to find. Also, create a shortcut to it in several places, like Start Menu, Task bar, Desktop.
I do that, and then routinely just copy that one folder to flash or other drive, so when working on another machine or travelling, I have an up-to-date listing. I tend to put other stuff in there as well, like themes, settings, fonts, cursors, downloads -- so whatever machine I'm working on, I can just copy that folder or use it, while on the other machine.
Hope this helps.
