Win95TruncatedExtensions

HKLM\SYSTEM\CurrentControlSet\Control\FileSystem

Data type	Range	Default value
REG_DWORD	0 | 1	1

Description

Specifies whether NTFS and FAT generate file names for new files with the 8.3 naming convention.

Setting the value of this entry to 1 does not change any existing file name extensions, nor does it change the way these extensions are displayed or managed by Find, File Manager, or Windows Explorer. However, it causes NTFS and FAT to generate short names for new files, and to truncate the third character of file name extensions.

The following table shows how "filename.html" would be truncated:

Value	Short name generated
0	filena~1.ht~
1	filena~1.htm

 

The following table provides an example of how this entry changes the file system's response to commands entered in a command prompt window.

Value	Command: del *.htm	Command: del *.html
0	Deletes only files with extension .htm.	Deletes only files with extension .html.
1	Deletes files with extensions beginning with .htm, including *.htm and *.html but not *.ht~.	Deletes only files with extension .html.

 

Activation Method

You must restart the computer for changes to this entry to take effect.
