Unfortunately, only one single tape can be saved for each level, so you have to decide if you want to keep an existing tape or save the current one. [...] manually copy it to your personal "tapes" folder [...] like "tapes/emc_amiga_mine_1/003.tape"
Notice that these things can be integrated. 'only one single tape'
exists as far as the game UI and engine are concerned. YOU can go into the filesystem can rename / move / copy / etc.
So, for instance, my ~/.rocksndiamonds/tapes/... hierarchy has 24210 files named '???.tape' (where '?' are all digits), and 1049 named '???.tape.orig', for cases where I decided some particular solution was worth saving, but then I played a 'better' one to be my 'official solution' for that level. And then, some 20-30 additional tapes with names like, for instance:
rnd_niko_boehm/025.tape.blue
rnd_niko_boehm/025.tape.green
rnd_niko_boehm/025.tape.red
rnd_niko_boehm/025.tape.yellow
rnd_richard_kleber/006.tape.blue
rnd_richard_kleber/006.tape.green
rnd_richard_kleber/006.tape.red
rnd_richard_kleber/006.tape.yellow
These files are from 2011 and 2014, so I don't 100% remember, but I'm pretty sure those were both levels where you have to make an initial choice of which door to go through, and you can't really get back to initial conditions; so I saved tapes of solving it in each direction.
