How can I do win xp system to hide only part of the file extension name

Generally speaking, we will choose to hide the extension name, because the file can be well protected, but sometimes we need to recognize the file attributes, so the extension name allows us to identify the file type more quickly, but Can you just show the extension of a part of the file? Windows' "Explorer" has an option to show or hide the file extension. If the display extension is selected, once the mailbox receives a malicious file such as "picture.jpg.exe", the full extension will make the file's tricks invisible; if the extension is hidden, "picture.jpg .exe” will appear as “image.jpg”, it is easy to be fooled. On the other hand, it always shows that the extension of all files does not look neat and tidy, and increases the risk of inadvertently changing the file type. The ideal solution is to display only certain file extensions that may be implicitly risky, while hiding the extensions of the remaining files.

First, force the extension of the EXE file. Open “Registry Editor”, find exefile (not .exe) in "HKEY_CLASSES_ROOT". Select the registration key, right-click in the blank space of the right pane of the Registry Editor, select “New →String Value", set the value of the name AlwaysShowExt, and then close the Registry Editor.

After modifying this registration key, the extension of the EXE file is always explicitly displayed in the "Explorer" or other software, even if you have selected "Clear Known Files". The same is true for the type extension & rdquo; option.

To maximize security, it is recommended to repeat the above steps for the following registration keys in "HKEY_CLASSES_ROOT": cmdfile, comfile (for Windows 2000/XP only), batfile, and scrfile. If you are concerned about someone sending you a malicious script file, you can also add the AlwaysShowExt values ​​for the following registration keys: JSFile, JSEFile, VBEFile, VBSFile, and WSFFile.

Expanding the name of this thing, we usually may not care about him, but if we really need to use the function, we will understand his purpose, if you have this need, you can use the above The way to do it.
