Cannot flash or verify in Particle Dev: "Please open a directory with your project"

[tjp]

Here’s what it should look like:

specifically the fact that I have only one folder open (using the above mentioned methods) and that folder only has one .ino file in it. You might also note that subfolders are possible as long as you understand that they are flattened on the build server so instead of #include "ClickButton/ClickButton.h" it’s just #include "ClickButton.h". That project compiles and is running on my photon as we speak.

Thank you! Now it worked for the first time!
I cleared up my directory structure in the left window, but i think it failed, because of an invalid symbol (“atom:”) in my working path. After removing it, it worked.

Do not use Add Project Folder... that is an Atom (the editor on which Particle Dev is based) feature that does not have a use in Particle Dev.

thank you! this fixed my issue
