I do not see a license listed for your codes. Would it be possible to add one or point me to where it is so I know the restrictions on using the provided code?

Thank you!

Hey @dholland4,

Honestly, I haven't touched C++ in 4 years, but this looks like fairly standard code.
Google search for the method name "GetFilesOfTypeInDirectory" yields only this gist as a search result, all the functions being used return results from Boost's documentation.

Seems like it depends on Boost and the standard library, but feel free to do whatever you desire to with these 9 lines of code, consider it a WTFPL license for this bit.

Have fun!
