Horodruin is a free tool for synchronizing files between different folders. According to the manufacturer's information, it has been prepared with advanced users in mind. In the case of standard applications of this type, we can synchronize the contents of two directories, but Horodruin goes one step further, allowing multiple folders to be synchronized at the same time.

However, before we decide to do so, we will have to add the appropriate catalogues to the program, and then we will get acquainted with their contents. Horodruin offers the ability to customize a number of settings, including masks, so that synchronization will take place according to the rules we specify (e.g. the application will synchronize only selected files, not entire directories).
