You seem to be missing a scandir implementation on Windows - one below - all yours :)

not missed.
i could extract also the scandir function from the dirent windows implementation.
if you think is better to integrate this func inside ImGuiFileDialog you can propose a PR if you want

Probably I found a different dirent implementation that didn't have that or I'm blind.. I guess you could be clearer about where to obtain the external dependencies. We both have it working, so doesn't matter which way you take it.

Thanks for the code. You're welcome to close this if you have everything resolved & I missed it.

yes i will precise that in the readme.
i though it was clear with how the sample app of this repo was made with dependancy in 3rdparty but maybe not haha :)
thanks for your advice.

i added infos in readme file.

the dirent version you must use is the v1.23. i had some issues before.
i pointed this version in readme.

let me know if its more clear for you
