Windows 10: Saving files on OneDrive deletes thumbnails

Good day,


I use a 3D modelling software called Revit, which creates a preview thumbnail of the current view when you save, which can then be viewed from Windows Explorer so that you have a preview of the model file before opening it:






However, when I save these files to my OneDrive, they lose their preview and appear as below:





Even if I resave, the thumbnails stay there temporarily but within a short period they are cleared. I imagine it has something to do with the synchronisation?


Please advise as to how I could resolve this. The previews are important for visually distinguishing between types.

Thumbnails of ICO files down't show up if stored in OneDrive


Ever since Microsoft OneDrive updated to Version 2017 (Build 17.3.7059.0930), all my PDF files that I have stored show thumbnails which never happened before. Great.





However, all my ICO (*.ico) files no longer show thumbnails after they are synched like they used to. Here is a screenshot I took showing the new icons I saved yesterday (which haven't been synched) and older ones that are synched.





How do I get my icon thumbnails back?

What I've already done:

1. Rebuild icon cache (Go to C:\Users\<your username>\AppData\Local\Microsoft\Windows\Explorer; delete all iconcache_*.db files)
2. Icrease size of icon cache (Regedit; KEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer; New String Value "Max cached icons"; Set to 8MB "8192")

 

Utilities that I run can no longer automatically save files to my OneDrive

Hi Alan,

Thank you for writing to Microsoft Community Forums.

To set OneDrive as your default location to save your documents and files, follow the below steps.

1. Click on the OneDrive icon from the Taskbar area > Click on the menu button (three-dots) on the top-right corner > Click on
   Settings > Go to the Auto Save tab.
2. Using the drop-down menu, select OneDrive for
   Desktop, Documents, and Pictures and click on
   OK.
3. Once you complete the above steps, restart the computer once and try saving the files generated from utilities and check if it is saving in
   C:\Users\myname\OneDrive\Documents folder.

If you are still facing the same issue, then I suggest you to contact OneDrive support for further assistance on this issue by following the below steps.

Recent (Save Files) - Change Default Settings to OneDrive


Hello -
Thanks for the return. Before I undertake changing the Registry, I have a question.
The steps in my Registry, for my version of Windows 10, were a bit different, but I think I eventually got to the right spot.
The last step is to change the number of places you want to list in Recent Places. In my case, the default Max Display listed 50 as the number. So, if I were to change that number, how do I know the Save As page will be one of those places? Or, a similar question, will this registry change delete the tab Recent from my Save As page? This is what I would like to happen.
When I received my computer in Nov. 2016, the Recent tab was not listed in the Save As page. Something caused it to be added over time. Which brings me to this second question. Would there be any benefit in deleting the changed registry listing and reverting back to the default listing? See attachment.
