The feature allows you to view the contents of compressed files, as if they were normal directories. The problem is that when you use Windows Explorer to view the contents of your hard drive it catalogues the contents of every compressed file, in whatever directory you are trying to browse. In principle this seems like a really good idea, but in practice if your directory has one or more really large compressed files in there, then the CPU goes through the roof and you sit there for however long it takes to catalogue each one and draw them on the screen. It can take ages!
Many thanks to Annoyances.org
for helping to provide the solution.
Turn it off:
- Open a command window, select Start Menu->Run.
regsvr32 /u %windir%\system32\zipfldr.dll at the prompt, and click Ok.
- The change will take effect immediately, but you may have to restart Windows for all traces of the built-in ZIP support to disappear.
