Solved Folder view settings not saving !

[GuccizBud]

As this post is over 3 years old, it's unlikely the OP is still waiting for a solution :sarc: but here's a likely solution if you're having this problem and your search results brought you here.

The most likely cause of the OP's problem, given everything that was tried and failed, was that the folder in question was inheriting the properties of the folder above it and this was superseding everything else. Isn't necessary to go into why this could happen, suffice to say it can and does—chalk it up to (one of many) problems/weaknesses within the Windows OS*. What's important is that it's easy fixable.

Let's assume this structure :

d:\parent-folder\child-folder
​

… and let's assume you're in parent-folder and the problem is with child-folder, which absolutely will not change from its "General Settings" view optimization setting no matter how many times you try to change it to "Video". In such a case what I'm suggesting is that the real problem is actually one level up, with parent-folder, and I suggest these steps  to fix it :


     ① Go all the way up to d:\
     ② Rename parent-folder to parent-folder-old (or something)
     ③ Create a new parent-folder


At this point you should still be in d:\ and the situation should be this :


          parent-folder-old   ⇐ this still contains child-folder as well as
                        anything/everything below it

          parent-folder     ⇐ this was just created and contains nothing
                        as of yet

Continue :

     ④ Go into parent-folder-old
     ⑤ Do Ctrl+A do select everything
     ⑥ Drag everything you highlighted into the new parent-folder


The easiest way to do this last is to click-drag everything you highlighted left, toward the navigation pane, position the cursor over parent-folder, then just let go of the mouse button … because you're staying in the same drive, Windows will treat that as an instantaneous Move, not a Copy (which is what you want), and when you let go of the mouse button everything that was highlighted in the main window (on the right) will instantly "disappear", having been moved from parent-folder-old to parent-folder.

Now finish up :


     ⑦ Go up to d:\
     ⑧ Delete parent-folder-old, which is now empty
     ⑨ Go down one level into (the new) parent-folder


You should now be in precisely the same place you were in just before you started with step ①, i.e. you should be inside parent-folder and looking at child-folder, the only difference being that you took child-folder and anything/everything below it on a ride which was basically a big circle, around and back to where it (and you) started . . . *but*, in doing so you will have broken the hold the original parent-folder had on child-folder, and you should find now that if you try to turn child-folder into a "Video" folder in folder customization properties, you will not have the problems you were having before.

* It can also be simply because the parent folder's folder view properties has its "Also apply this template to all subfolders" checkbox selected . . . I don't know which is supposed to have higher priority between a folder's view settings and that folder's parent's view settings having its "Also apply this template to all subfolders" checkbox selected. I'd like to think Windows won't insist on propagating a parent folder's view properties down the chain if you specifically indicate you're trying to set a child folder's view settings differently, but maybe it does, or maybe it isn't supposed to but has a bug where it still does sometimes. Whichever the case, the procedure outlined will take care of the problem, at least insofar as the folder problem at hand is concerned.
