Failijagamissüsteemid, known in English as file-sharing systems, are a type of distributed application software that allows users to share files over a network. These systems typically operate using a peer-to-peer (P2P) architecture, where each user's computer acts as both a client and a server. This means that users can download files from other users' computers and simultaneously make their own files available for others to download.

The core functionality of a file-sharing system involves indexing files that are available on participating computers. When a user searches for a specific file, the system queries its index to locate other users who have that file. Once a match is found, a direct connection is established between the two users, and the file transfer begins. This decentralized approach eliminates the need for a central server to store and distribute all files, making the system more resilient and scalable.

Early file-sharing systems, such as Napster, often faced legal challenges due to the unauthorized distribution of copyrighted material. However, the technology itself has evolved. Modern file-sharing systems can be used for legitimate purposes, including the distribution of open-source software, educational resources, and large datasets. They are also employed in various enterprise environments for efficient internal file distribution. The underlying principles of P2P networking continue to be explored and utilized in other distributed computing applications.
