[Easytag-mailing] Strange File Display Order Question

["Alastair" <ajebay errichel co uk>]

Hi,
Using Easytag 2.1.7 to edit tags of BBC Podcast mp3 files (In Our Time Archive).

These podcast files do not have a track number when downloaded but when viewed in 
Easytag they appear in alphabetical order of Title tag or file name, except for files using x,y 
or z which are put first in list and then followed by a,b,c etc.

For example file title  "IOTS: Zero" is before "IOTS: Ageing," "IOTH: Xenophon" is before 
"IOTH: Africa," "IOTC: Yeats and Irish Politics" and two more IOTC: Y... are before "IOTC: 
Abelard..." Could somebody please explain why this might be?

I use Twonky on NAS device to distribute multimedia data and the absence of track number 
with these BBC podcast mp3 files also appears to cause strange results with uPnP client 
players and I think I shall need to use scanner to write track number based on alphabetical 
order but without the above anomaly. Any views on if this is the right way to proceed and 
how can I use the scanner to pick up true alphabetical order and insert file number?  I regret 
it is beyond my experience.

Grateful for advice/suggestions.
Budgie
