Short file names
Every time you create a file with a long file name, NTFS creates a second file entry that has a similar 8.3 short file name. A file with an 8.3 short file name has a file name containing 1 to 8 characters and a file name extension containing 1 to 3 characters. The file name and file name extension are separated by a period.
If you have a large number of files (300,000 or more) in a folder, and the files have long file names with the same initial characters, the time required to create the files increases. The increase occurs because NTFS bases the short file name on the first six characters of the long file name. In folders with more than 300,000 files, the short file names start to conflict after NTFS uses all of the 8.3 names that are similar to the long file names. Repeated conflicts between a generated short file name and existing short file names cause NTFS to regenerate the short file name from 6 to 8 times.
To reduce the time required to create files, you can use the fsutil behavior set disable8dot3 command to disable the creation of 8.3 short file names. (You must restart your computer for this setting to take effect.) For more information about disabling 8.3 short file names, see "MS-DOS-Readable File Names on NTFS Volumes" later in this chapter.
If you want NTFS to generate 8.3 names, you can improve performance by using a naming scheme in which long file names differ at the beginning instead of at the end of the name.
For more information about short file names, see "File Names in Windows XP Professional"
