This is in reference to music players

Will leading zeros cause reading errors or improper sorting?

Will having 01/15 track 1 of 10 be read 01/10 and or cause reading errors or improper sorting?

If the track is 4 digits long to include the disc number  
and track number will it be read or cause errors?

Thanks

With the players I've used, a leading '0' was necessary for correct sorting.

It could be.  
For some reason assumes Windows Explorer that 3-digit-numbers with leading zeros have octal (instead of decimal) values.  
So it could be that some filenames with leading zeros are sorted in strange ways.
