File Explorer in Windows 11 seems to have quite a few flaws. It can load slowly when you open files, and sometimes, Explorer's search bar can take a long time to load your search results.
But Twitter user Vivy has discovered a bug that can significantly speed up Windows File Explorer. According to Vivy switching File Explorer to full screen mode (pressing F11) and then exiting full screen mode (pressing F11 again) results in almost instant loading of folder contents and thumbnail previews of files. The search function in File Explorer also becomes much faster.
Users on the r/Windows 11 subreddit report that a bug in File Explorer actually improves load time. A Redditor he said:
I tried it on a music folder with 1800+ subfolders and 25.000+ files: Everything opens instantly. This is the performance we had in Windows 7 Explorer.
Another one He wrote:
I just tried it on an i7-7700HQ in build 22H2… And it works. I can not believe it. It's so fast all of a sudden. Now, I don't know if I should be happy or pissed off about this.
This bug apparently affects all Windows 11 builds, from Canary Insider builds to the original build (22000, 21H2).
Although the bug makes File Explorer faster, it would be much better if we had this performance by default. Windows 11 was supposed to have better overall performance than previous versions, but that doesn't seem to be the case.
