You should start reading here:
Please be aware that Windows can’t use the character “/” as part of a file name, because “/” is one of the reserved charaters like * or : or > or < or ? and some more.
Therefore you can’t name your song
01/ Song Title/ 01 /CD Title /Artist
A possible filename would be
01 - Song Title - 01 - CD Title - Artist.mp3
(whatever your reason is that you want to repeat the tracknumber)
or
Artist - CD Title - 01 - SongTitle.flac
For a better understanding what the windows explorer show:
#1 shows the filenames of your songs with the extension (like .mp3)
#2 shows the embedded (ID3) tags in the files
