Hi everyone!
My name is César and I’m learning how to use Elixir. My goal is to create some kind of web crawler to locate historical data. Anyway, right now, I am into a more mundane task.
I’m trying to create some programs in Elixir than help me sort my files. For example, I’d like to sort my files by extension or order my photos by modification date. I thought that it would be an easy task, but there are not so many examples of how to traverse directories and move files. I’ve checked on Exercism and several online books, but I am always taken back to the reference manual.
I’ve seen the Files.rename/2 information, but given my current Elixir level, I’m not sure about how to combine it with safeguards so the results are not disastrous. (For example, I might have several source files called IMG_0001.jpg and I don’t want to have them silently overwritten).
Do you know any source that might have this kind of file management examples? Any cookbook that covers this? Most resources flow like Install |> Strings and binaries |> Flow control |> OTP BeamVM, skipping the file chapter 
Thanks for your support!
