These days almost everyone uses services like Dropbox or mega.nz to store their important files and have them accessible wherever and whenever they need them. I’m told it is not uncommon to use these external services to back up all one’s files, from photos to sensitive and private documents. Well, good news. If you actually care about your files and feel uneasy to have them all in other people’s servers, you may want to have a look at Syncthing, an open source and free (as in free beer) continuous file synchronization program that synchronizes your files between your computers without being stored or ever going through third parties. In this post I’ll talk about how it works and how to set it up to sync directories between your computers, laptops and phones.
