Thanks, I had been using the ImgBurn default ISO9660+udf In advanced->restrictions->ISO9660 I now selected level2 with 2-31 character names this then gave correct alphanumeric play order in mp3 player. [player supports joliet, but with ISO9660+joliet I concluded player seems to ignore joliet whilst ISO9660 still present] Thanks for the advice you gave in resolving this. Regards, Paul

Thanks, I tried ISobuster in fact this lists the files in the same order as isoinfo but following your comment to look at LBA (Location of extent) these offset addresses, if I interpret them corrrectly, do show the correct burn order is respected; so both tools give file list in the order that matches play order these show an abbreviation of the file names as follows 36177343 May 4 2010 [ 68883 00] WHOPIT_2.MP3 = whopit_tue1_04052010.mp3 35571504 May 7 2010 [ 121356 00] WHOPIT_F.MP3 = whopit_fri4_07052010.mp3 35508978 May 4 2010 [ 104017 00] WHOPIT_T.MP3 = whopit_thur3_04052010.mp3 35774521 May 4 2010 [ 86548 00] WHOPIT_W.MP3 = whopit_wed2_04052010.mp3 35514264 May 3 2010 [ 51542 00] WHO_MON_.MP3 = who_mon_morb8_03052010.mp3 35005839 Apr 28 2010 [ 17370 00] WHO_MOR2.MP3 = who_morb6_28042010.mp3 34976715 Apr 28 2010 [ 34463 00] WHO_MOR3.MP3 = who_morb7_28042010.mp3 35015258 Apr 23 2010 [ 272 00] WHO_MORB.MP3 = who_morb5_23042010.mp3 [lba is inside square brackets] play is then based on alphabetic sorting of abbreviated name which does not match the same alphabetic order as original files (how is abrreviated name derived) nonethless, as you say, it would seem if I prefix the name at the start (which does not seem to be impacted by 'inaccurate' abbreviation) it will make the play order correct seems alphabetic order must be correctly expressed in first 7 characters of file name ? Thanks, Paul

Thanks, specifically these were the names of the files as specified in the source list; effectively diverse mp3's I wanted to play in this order without inconvenience of prefixing with a numeric index (a solution I had adopted successfully before on mp3's where they were all tracks on the same album with pre-fixed/base name being same for all files ) who_morb5_23042010.mp3 who_morb6_28042010.mp3 who_morb7_28042010.mp3 who_mon_morb8_03052010.mp3 whopit_tue1_04052010.mp3 whopit_wed2_04052010.mp3 whopit_thur3_04052010.mp3 whopit_fri4_07052010.mp3 order these played on a alpine mp3 changer was whopit_tue1_04052010.mp3 whopit_fri4_07052010.mp3 whopit_thur3_04052010.mp3 whopit_wed2_04052010.mp3 who_mon_morb8_03052010.mp3 who_morb6_28042010.mp3 who_morb7_28042010.mp3 who_morb5_23042010.mp3 I tried to understand why alphabetic order was not respected [alphabetical order for above would be who_mon_morb8_03052010.mp3 who_morb5_23042010.mp3 who_morb6_28042010.mp3 who_morb7_28042010.mp3 whopit_fri4_07052010.mp3 whopit_thur3_04052010.mp3 whopit_tue1_04052010.mp3 whopit_wed2_04052010.mp3 ] after burning to a cd, I had written the iso image back from the cd and inspected it with isoinfo command which reported the same order as the chnager play order - I could not find a mechanism in imgburn itself to inspect the physical order [./isoinfo.exe -l -i /cygdrive/c/Nobackup.iso] I concluded I just needed to get physical order to be play order I wanted so I tried using the 'sort files by source list order (*)' option but this did not cause the order to change as reported by isoinfo. I believe that when I had previously seen the prefix mechanism working this was because physical order generated by imgburn had coincidentally matched the alphabetic order, as opposed to player automatically playing alphabetically. I was also exploring adding mp3 title/track tags as a mechanism to fix play order, but this is equally inconvenient to prefixing files. Regards, Paul

Hi, I tried to use tools -> options -> build -> 'sort files by source list order (*)' option hoping that this would modify the order in which the files were put in the image to follow exactly the file order I see in the source list but it has no impact and order is not respected - please can you explain its functionality. [i guess I have misunderstood option as it is already possible to specify an order of the files in the sources list itself - moving files up and down list, which would make 'sort files by source list order (*)' redundant I do not understand the significance of the '*' either there seems to be no accompanying note] I am trying to prepare a cd with mp3 files for a player which plays in the order in which the files are burned as opposed to playing them after an aphanumeric sort. I checked the order in which the files had been written by creating an image from a burned disk and then displaying files with 'isoinfo -l -i' command which concurred with the order the mp3 player played them; and this order does not match order from source file list. Thanks for any advice you have, Paul
