File Chooser details always seem to get reset

I still have not found a solution and this changes daily, but I did find some good references to the general nature of ShellBags:

New Win7 reg entries related to folder views - Windows 7 - MSFN

Unfortunately, these are all for Win 8 and earlier.

It's pretty much the same in Windows 10 other than disabling auto arrange no longer works properly.

The 'ColInfo' parameter seems to be the Folder View column list.
I've been unable to find anything about it.
Most of my 'bags' have the same value for this, but not all.
The Generic folder type clsid is {5C4F28B5-F869-4E84-8E60-F11DB97C5CC7}
The 'New Win7 reg' reference above has some intriguing settings for:

Code:

;Disable sniff folder feature in Windows 7 and sets folder type to not specific
;______________________________________________________________________________
[HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\Shell\Bags\AllFolders\Shell]
"KnownFolderDerivedFolderType"="{57807898-8C4F-4462-BB63-71042380B109}"
"SniffedFolderType"="Generic"
"FolderType"="NotSpecified"

and

Code:

;Generic - Folder Template Global set because folder type is set to not specified above.
;First template is what is used for all types of files in windows
;Rev key when set to 0 shows Auto Arrange and Align to grid in menu
;FFlags turns off Auto Arrange when set to 43000000 and 43000001 is on
;Vid sets the type of file that is in the folder icons, list, thumbnail, tiles etc
;mode is the icon size used in vid 10/30/60/100 Small/Medium/Large/X-Large Icons
;Tiles vid uses 30 on and details and list views use 10 only.
;sort is how the folder is sorted. Type, name etc
;All templates can be set same as generic but can be modified if you decide to use them.

If you put the key 'Inherit' under a bag, that simulates the checkmark for applying to all folder types.

This sounds really dangerous - I think I can probably play with a few bag settings and force inheritance on all remaining bags, since they all start with 'Dekstop'.

Anyone want to try that? I'm chicken.

Also, this reference

FOLDERTYPEID (Windows)

Describes the many folder types. There are more than just Documents, Pictures, etc.

On my system there seem to be many dozens.

FOLDERTYPEID values are GUIDs and are declared in Shlguid.h.

In practice, any FOLDERTYPEID value can be applied to any folder regardless of that folder's contents. The FOLDERTYPEID is a view template only, supplying appropriate layout and columns for the expected folder content. There is no verification of the folder contents against the FOLDERTYPEIDvalue to ensure suitability.
These and other folder types are defined in the registry under the FolderTypes subkey, which is located as shown here:
HKEY_LOCAL_MACHINE
SOFTWARE
Microsoft
Windows
CurrentVersion
Explorer
FolderTypes

You could create a restore point before playing with it. This way you could do a system restore using the restore point to undo it if you don't like what it did.

I have restore points disabled, I just do full image backups.

I keep C: small so my backups are fast, frequent and I don't need restore points (which only make the backup bigger).

I've found that when I go into these types of customization, I just get bit by the next windows update, or some upgrade no longer works, or Acronis tries to install itself on my I: drive or ...

In other words, I can't seem to make the truly simple system that I'd like - Windows just loves complexity.

I have tried the following RegEdit file and it seems to work well enough. There are still a few problems, but most folders show up looking fine to me.

Libraries and their handling seems to be broken In Windows 10 as far as folder view handling goes.

Code:

Windows Registry Editor Version 5.00


; remove all bags
[-HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\Shell\Bags]




[HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\Shell\Bags\AllFolders\Shell]


; make derived folders use details view
"KnownFolderDerivedFolderType"="{57807898-8C4F-4462-BB63-71042380B109}"


; make folders look like Generic folders
"SniffedFolderType"="Generic"
"FolderType"="NotSpecified"


;inherit these settings
[HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\Shell\Bags\AllFolders\Shell\Inherit]
"FolderType"="Generic"

Libraries are in their own little world.

I guess it is because Libraries are combined views of possibly many folders, so they have to trigger a specialized view mode to allow the folders to be grouped and organized.
