FAT Registry Entries

The following registry entries are associated with the FAT file system.

The information here is provided as a reference for use in troubleshooting or verifying that the required settings are applied. It is recommended that you do not directly edit the registry unless there is no other alternative. Modifications to the registry are not validated by the registry editor or by Windows before they are applied, and as a result, incorrect values can be stored. This can result in unrecoverable errors in the system. When possible, use Group Policy or other Windows tools, such as Microsoft Management Console (MMC), to accomplish tasks rather than editing the registry directly. If you must edit the registry, use extreme caution.

FileSystem

The following registry entry is located under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\FileSystem.

Win95TruncatedExtensions

Registry Path

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem

Version

Microsoft Windows NT 4.0 Server and Windows NT 4.0 Workstation and later.

Truncates extensions on FAT partitions, allowing you to work with 3-character extension files as well as 4-character extension files (for example, *.htm is treated identically to *.html).

For more information about this registry entry, see the Registry Reference in the Tools and Settings Collection.
