When you have a lot of MP3 music, the following question arises: how much of that music will I transfer to my portable MP3 player? And not only that, but: which of those MP3s will I transfer? Well if you see that it is impossible to decide, then the solution is Random Fill.
The Random Fill mode of operation is very easy: simply choose, in a completely random way, the MP3s that are going to be selected. You just have to indicate which folders the MP3s are in and it will take care of picking them up at random without any specific criteria. In this way, you will always be surprised to hear it, because you will not know the songs chosen.
The Random Fill user is the one who specifies the maximum size that the total selected MP3 files must have in order to ensure that they fit in the portable player without exceeding its capacity.
You can free download Random Fill 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
