Android/iOS: Snapchat announced a new feature yesterday that allows any user to delete any messages they send in individual or group conversations.

There might be reasons why you want to keep your Tumblr account but delete all your posts. Perhaps you land-grabbed an awesome Tumblr username or URL and you don't want to give it up, but you'd rather people not know about how into anime GIFs you once were, your dark obsession with Henry Cavill, or how often you post about cats during the 9-5 work week. Things like that.

This one's almost a cop-out, since all Windows users should know about WinDirStat by now. This app has been out for nearly 15 years, and it's one of the most helpful tools you can use to clean up your hard drive.

It's been nearly a decade since we last checked out Lockhunter, an incredibly useful Windows app that ensures you'll always be able to remove files and folders that File Explorer refuses to delete. Developer Crystal Rich Ltd continues to update the app with useful features, but sporadically: It took around 3.5 years to go from version 3.1 of the app to version 3.2.

I encountered a quirky problem the other day when I was trying to clean up one of my hard drives before copying its contents to another drive: I couldn't delete a folder.
