The Sort Order for Files and Folders Whose Names Contain Numerals Is Different in Windows XP Than It Is in Windows 2000

The sort order that is used by Windows XP for files and folders whose names contain numerals is different from the sort order that is used by Windows 2000. The following example shows the difference in sort order that is used by the two operating systems to list folders in Windows Explorer when the names of folders contain numerals:

Windows XP

Windows 2000

Ie4_01
Ie4_128
Ie5
Ie6
Ie401sp2
Ie501sp2

Ie4_01
Ie4_128
Ie401sp2
Ie5
Ie501sp2
Ie6

By default, in Windows XP numerals in strings that are contained in file and folder names are considered to be numeric content, not text. Numerals in folder and file names are sorted according to their numeric value.

In the example that is described earlier in this article, the Ie401sp2 folder is listed after the Ie6 folder when you sort the folders by name in descending order because 401 is a numerically higher value than 6. In the following example, note how the following files, whose names contain numerals, are sorted in Windows XP and in Windows 2000:

In Windows XP

In Windows 2000
5.txt
11.txt
88.txt

11.txt
5.txt
88.txt
