How to make windows display only certain file extensions

Windows "Resource Manager" has an option to show or hide file extensions. ", It is easy to be fooled. On the other hand, it always shows that all file extensions do not look neat enough and increase the risk of unintentional changes to the file type. The ideal solution is to show only some file extensions that may be implicitly risky, while hiding the extensions of other files.

First, force the extension of the EXE file to be displayed. Open the "register table Editor" tab and find "exefile(not .exe)" in "Export hkey_classes_root= ). Select the registration key, right-click the blank position in the right pane of the Registry Editor, select "New> string value", set the value name alwaysshowext, and close the registry editor.

After the registration key is modified, the extension of the EXE file is clearly displayed in resource manager or other software, the same applies even if you have selected the "Hide extensions of known file types" option.

To maximize security, we recommend that you repeat the following registration keys in "hkey_classes_root": external file, comfile (applicable only to Windows 2000/XP), batfile, and scrfile. If you are worried that someone will send you a malicious script file, you can also add alwaysshowext values for the following registration keys: jsfile, jsefile, vbefile, vbsfile, and wsffile.
