Files without extension

Hello,
How can I accept files without an extension into my file upload?
Thank you.

Hi, what type of file?

https://community.wappler.io/t/uploading-single-file-to-your-server/4231

.rar, .zip, .7zip, .bin, -> this format works very okey

instead of this I need to be able to select a file which has not “.noextension” when I open file selector.
