What is a .swn file?

File Extension Details

A file with the SWN extension is a temporary swap file created by the Vim (Vi IMproved) text editor. When a user opens a file for editing in Vim, the application creates a hidden swap file to store the current state of the document and any unsaved changes. This mechanism serves as a crucial recovery tool in the event of a system crash, power failure, or unexpected termination of the software. While the primary swap file typically uses the .swp extension, Vim uses a specific naming convention for subsequent swap files if multiple instances of the editor are running or if a .swp file already exists in the directory. It cycles backwards through the alphabet, resulting in extensions like .swo, .swn, .swm, and so on. These files contain binary data representing the buffer's contents and are not meant to be opened or edited manually by users. Instead, when Vim detects an existing swap file upon opening a document, it prompts the user to recover the session, delete the swap file, or quit. Once a session is closed normally and changes are saved, Vim automatically deletes the associated swap file.
