How do I make my storage solution work properly?

Okay, don't get me wrong, I really do like Windows 10. My computer runs better than it did before and some of the little glitches I had with W7 are now gone. The problem I have is that I had certain hard drives set for certain things. I had my capture video on D, my rendered video on E, my pictures, music, and docs on F. If I use the default storage folders in the settings along with that new folders are created and I can't place things exactly where I want them. What can I do? Anyone else in this dilemma?

i'm confused on what you want... sorry ... :(

"quick access"
Right click, try using "quick access" on folders and drive.
It will put icon in the file explorer near the top.
Remove the other quick access selections if needed.

As far as setting up applications where to access from and save to is usually in that apps preferences.

you can also right click on the folders in quick access and go to properties. then you can go to the location tab and select move. that will let you move the symbolic link for documents, movies, ect to whatever folder you intended.
