Although now that's highly doubtful, because I'm the unluckiest of all unlucky people who ever experience bad luck.
I started archiving 46 GB in WinRAR, simultaneously splitting it into parts to burn onto a hundred DVD discs. I set the settings so that the size of one part would be DVD+R. It took five hours to process everything, and another five hours remained. I finally decided to start burning, and – oh dear! – there are 3.** megabytes less free space on the disc than the size of one part.
:D That's epic, in my opinion))
I thought WinRAR wasn't stupid and knew how much free space there was on a DVD-R disc.
However, now I'm making normal volumes for myself, but without compression, because it will be fifteen times faster.
I'll have to spend a little more on how many discs, at most one :D
