Visual Studio 2019 does not show all files in a folder

Question

After a recent upgrade of Visual Studio 2019, why is Solution Explorer no longer showing all files in a folder?

Answer 1

1. Create a new folder with a temp name.
2. Use add to add the files from the broken folder.
3. Once you have done that delete the broken folder with the original name.
4. Rename the new temp folder to the original name.

Answer 2

No, the problem is not fixed on my computer. A temporary solution has been to right click on the folder with missing files then go to Add - Existing Item... However, when I close and reopen Visual Studio, added items disappear again.

Answer 3

This is ASP.NET website
Yes, In Solution Explorer I see the root Solution node and then a project node.
I the root solution node, I now see [Show All Files] and it has been checked
If I Right click the project node and use 'Open Folder in File Explorer', it shows all source files in that folder.

Answer 4

I do not see the small icon for show all files.
Also, the folder which does not show all files is cut off alphabetically. It only shows file names beginning with A through C

Answer 5

Have you checked the small icons up top on the right hand side of VS? One of them is show all files. You might need to click it to see all your files.
