I'm a big fan of the original project, so I'm curious what the changes amount to. (It claims there are performance improvements, but nothing detailed.)
Voidtool's Everything is one of those things I pretty much can't use a PC without. It's just stunningly useful and performant. MSFT's file search is so slow in comparison it feels almost like a malicious prank.
Pretty sure they said it's because it doesn't support permissions, so you could see anything on your hard drive, that's why they don't support it and do indexing instead
The operating system doesn't need permissions to see anything on your hard drive and it is the operating system that is enforcing the permissions so it can filter the results afterwards. Also, an index can be stale and show files whose permissions have changed that you shouldn't be able to see so the permissions have to be checked on the search results either way.
It and WinDirStat are some of the first things I install on any new instance of a computer. But I may check out this fork and Whiztree for other inspiration.
Disk Inventory X has been a little hit or miss for me. Works OK on my two Macs (Catalina), but can’t index the whole (128GB?) drive on my wife’s MacBook Air (Mojave). Just crashes at some point.
I've also been using WizTree for quite a while, but recently learned WinDirStat scans the filesystem instead of trusting the NTFS metadata because it can sometimes be incorrect(?) and is a bit tricky due to poor documentation.
The WDS developer actually addressed this in AWDS's issues 4[1] and 19[2] a few years ago, and even said he's contemplating supporting the MFT but it seems he hasn't gotten around to it.
