#Include is not populating files outside of folder scope in Solution Explorer

When I type #include “”, only the files inside the folder I am in populate.
I can type in the path of other files outside this folder scope and I have no problems, but it use to populate for me.

I went into “Project->Properties->VC++ Directories” and have tried manipulating Include Directories, but nothing changes. Also, Include Directories is over 16,000 characters long, which I find is a little bit odd, but I haven’t looked at it before.

I’ve attempted research on this issue, but am afraid I came up short / unsure how to specify what’s happening.
Please let me know if there are any details that are needed that I failed to provide / clarify.

Any help is appreciated and thank you for your time.


Posting an update. I am no longer able to include other header files outside of the current file’s folder scope. I’m unsure what happened. The only thing I’ve done since then was closing Visual Studio and re-opening it.
