Hi,
I have no idea why this is not working anymore. I remember this used to work where I could search and select look in <Workspace> or <Project> for only files I have in my project, not every file in the directory. I had to resort to "Search Files" which searches the entire Linux Kernel source tree for /arch/... devices I don't even care about giving me an overwhelming return and useless list.
I am using SlickEdit Version 15.0.1.3. I was going to upgrade so I can work seamlessly with VS2017 but not sure if this will have same lacking behavior.
