What is a .RPP-BAK file?
RPP-BAK is an automatic backup of a Reaper project - a copy of the .rpp session the REAPER digital audio workstation saves so you can recover earlier work.
- Did you know
- Reaper quietly writes a .rpp-bak each time you save, so a corrupted or mistakenly overwritten session can usually be rolled back a step.
- REAPER is a low-cost, highly customisable DAW from Cockos, known for its tiny installer and honour-system licensing.
- An .rpp project, including its backup, is plain text, so a session can be inspected or even hand-edited to fix a problem.
- What Analyser shows you
- Open Ableton Live sets (.als/.alp) and Reaper projects (.rpp) and see the arrangement drawn out: one row per track, every clip positioned exactly where the project puts it, on a real clock with a zoom for busy sections. A project file contains no audio at all - it is an edit list - so what is shown is read from the same numbers the DAW lays the session out with. Reads the tempo, time signature, track list with each track's type, clip count and plugins, and the media files the project points at but does not contain, which is what tells you whether a session that has been moved will still open complete. An Ableton set is gzipped XML and times everything in beats, so the tempo is what makes a real timeline possible; a Reaper project is plain text and already stores seconds.
