what I've discovered... On Mac OS anyway… The files being moved to archive and replaced with zero-byte files still happens every single time I copy files to the synced folder. I now know exactly what is happening; MacOS creates temporary zero-byte placeholder files when copying files. They’re the little greyed-out ones that show until the actual file is copied to a folder. Resilio sync is quickly syncing those placeholder zero-byte files to computer 2 before the actual files are finished copying to the sync folder locally on computer 1. Since those zero-byte placeholder files have now made it to computer 2 and have a newer timestamp than the actual files, Resilio Sync is determining that they should be kept instead of the actual files, so it is back-syncing those zero-byte files from computer 2 over the actual files on computer 1, and moving the actual files into the archive folder. The only way to prevent this is to close Resilio Sync completely while copying any files to the sync folder. This way Resilio doesn't have the chance to sync those temporary zero-byte placeholder files in the first place. Hopefully this can be fixed in an update
