Visual Studio Code: Unable to open 'MyFile.h': File not found

Question

I got this kind of errors when attempting to go to the declaration of some attributes/methods (using ctrl/cmd + left click):

Unable to open 'MyFile.h': File not found

probably this happens because the file MyFile.h has been moved recently.

Answer 1

I had the same behavior when browsing the file changes in the source control panel but for me the issue was that while I was reworking my project architecture, I had a remaining .gitmodules file in the root of my project, but the subdirectory was not a repository itself.

So I just deleted the .gitmodules file and it worked again.

Answer 2

I had the same issue and solved it by reloading my VS code window.

Ctrl + Shift + P on Windows

Command + Shift + P on Mac

Type:

Reload Window

Then select Developer: Reload Window

Answer 3

I solved this problem by forcing VSCode to re-scan the project structure.

In order to do that, I closed VSCode, deleted the .vscode hidden folder of my project, and opened it again.
