Disabling Native ZIP Support in Windows XP

Windows XP includes built-in support for creating and opening ZIP files, but it’s capabilities are nowhere near as robust as third-party ZIP management tools like WinZIP, Filzip and other popular compression programs.

While there’s technically nothing wrong with leaving both XP’s built-in ZIP capabilities and a third-party tool installed simultaneously, some performance improvements can be had by disabling XP’s native ZIP support.  Disabling XP’s native ZIP handling capabilities is a simple matter of unregistering the DLL file associated with the feature, namely zipfldr.dll.

To disable XP’s native ZIP support, click Start > Run and then type the following the Open text box:

regsvr32 /u zipfldr.dll

Click OK, and when the RegSvr32 dialog box appears, click OK to confirm that the file was unregistered. Reboot and from that point forward, use your preferred third-party ZIP utility as you normally would.

To re-enable native ZIP support, enter the command regsvr32 zipfldr.dll
