What is a .!SYNC file?
A .!SYNC file is a type of file that you might see when you're using BitTorrent to share or download files with others over the internet. BitTorrent is a way for a lot of people to share files directly with each other, instead of downloading them from a central server. This file-sharing method is often called peer-to-peer, or P2P, file sharing.
The ".!SYNC" part at the end of a file name means that the file isn't fully downloaded or shared yet. Think of it like a bookmark or a placeholder. It shows that BitTorrent is still working on getting the whole file. This could happen if the download process gets interrupted or if it's just taking a long time to finish.
You can open these .!SYNC files with a program called Resilio Sync. Resilio Sync is a tool that helps you sync files between different devices, like your computer and your phone, or between you and other people. It's made by the same people who created BitTorrent, so it works well with these .!SYNC files.
Here's something important to remember: if you see a file with .!SYNC at the end, it means it's not ready to be used yet. The file is incomplete. Once BitTorrent or Resilio Sync finishes downloading the file, the .!SYNC part will disappear from the name, and you'll have the full file ready to go.
If you delete a .!SYNC file thinking you don't need it, BitTorrent or Resilio Sync will just start downloading the file again from the beginning. So, if you see a .!SYNC file, it's usually best to just leave it alone until it's done.
