Magic sort order of DOS DIR command
This is output from Mp3tag Cover Export. Yesterday I got following situation, see sort order of files, incorrect output on option /o-dne. CODE O:\TEST\COVERS>dir 1*.* /odne 13.03.2008 20:34 5.286 1.jpg 13.03.2008 20:34 7.813 1(1).jpg 13.03.2008 20:34 3.475 1(2).jpg 3 Datei(en) 16.574 Bytes O:\TEST\COVERS>dir 1*.* /o-dne 13.03.2008 20:34 7.813 1(1).jpg 13.03.2008 20:34 3.475 1(2).jpg 13.03.2008 20:34 5.286 1.jpg 3 Datei(en) 16.574 Bytes Today, with newly created files, I got following situation, see sort order of files, correct output on option /o-dne. CODE O:\TEST\COVERS>dir 1*.* /odne 14.03.2008 09:16 5.286 1.jpg 14.03.2008 09:16 7.813 1(1).jpg 14.03.2008 09:16 3.475 1(2).jpg 3 Datei(en) 16.574 Bytes O:\TEST\COVERS>dir 1*.* /o-dne 14.03.2008 09:16 3.475 1(2).jpg 14.03.2008 09:16 7.813 1(1).jpg 14.03.2008 09:16 5.286 1.jpg 3 Datei(en) 16.574 Bytes So what the heck is going on there?

You could check the entire D (Date/Time). In my german DOS, the help shows the following explanation:
QUOTE ("german DOS") D Datum/Zeit (ältere zuerst) I think your files have some additional (but not visible) information in the time: The seconds. Maybe this seconds make the difference in sort order? |

QUOTE (LyricsLover @ Mar 14 2008, 17:34)  You could check the entire D (Date/Time). ... This is what I did, see option /o-dne, that means sort by date in reverse order. Could it be that the filesystem registers two files at the identical time point, when they were created in sequence one after another by Mp3tag cover export? DD.20080315.1717.CET I checked it again and see what happened: CODE O:\TEST\COVERS>dir *.* /od 15.03.2008 18:08 3.475 1(2).jpg 15.03.2008 18:08 7.813 1(1).jpg 15.03.2008 18:08 5.286 1.jpg 15.03.2008 18:08 22 identify.in.txt 15.03.2008 18:08 4.110 Mp3tag.magick.identify.cmd 15.03.2008 18:11 <DIR> .. 15.03.2008 18:11 <DIR> . O:\TEST\COVERS>dir 1*.* /od 15.03.2008 18:08 3.475 1(2).jpg 15.03.2008 18:08 5.286 1.jpg 15.03.2008 18:08 7.813 1(1).jpg Identical sort order /od using different search masks gives different sort results. Looks like a DOS bug. DD.20080315.1822.CET This post has been edited by DetlevD: Mar 15 2008, 18:21 -------------------- * Beyond that, don't ask, when you don't know what to do with the answer. *
