fog， File Organizer written in Go

A little tool to help organize files easier.

Note

This project is a small prototype from my early days of learning Golang, approximately 10 years ago.
While it may still be functional, it has undergone limited testing.
Caution is advised, particularly in production environments.
Every commit generates a log, enabling easy reversion if necessary.
However, please be mindful of potential risks before proceeding.
