Here’s an interesting bit of news. After seeing reports about folders that end with a .tmp extension (!) in Windows 11, i found some on every machine I checked running that OS. These folders are invariably empty, and may be safely deleted. When I say: Kill these Windows 11 tw*.tmp folders, you shouldn’t suffer any adverse effects if you take that advice.

Why Kill These Windows 11 tw*.tmp Folders?

Because they’re empty. Because you don’t need them. And because they can swamp the other, valid data in that folder.

My other Beta and Dev Channel PCs had between 40 and 50 such folders in the same directory, by way of comparison.
