Vim's buffer management feature can efficiently handle multiple files. Buffer operations: :ls or :buffers to list all buffers, :b[n] to switch to buffer n, :bn for next buffer, :bp for previous buffer, :bf for first buffer, :bl for last buffer, :bw to delete buffer, :bw! to force delete buffer. Buffer status: # for alternate file, % for current file, + for modified, - for read-only, = for read-only and modified, a for active, h for hidden. Buffer list navigation: :b# to switch to previous file. Buffers and windows: each window displays one buffer, one buffer can be displayed in multiple windows. Buffer management is very important for editing multiple files simultaneously and quickly switching between files, and is the foundation of multi-file editing.
