Haha, we have only a handful of PCs that upgraded to Win11 so far. I think it’s just as bad as Win10, maybe better than Win10 18H2 and earlier apart from the UI.
For totalcmd: Viewer than can easily search an 8GB binary file at the speed of the disk, switched seamlessly between UTF-16, ASCII, HEX. The whole Search feature now integrated with Everything. Multi-Rename with Regex and or renumbering. Treeview that can be enabled or disabled for one or both panes. Copy/Move queue with speed limiter and pause. Tab management for sorting and removing duplicates. History of most frequently used directories. Integrated wget (via the FTP-URL button). Fast image gallery view. That’s what comes to mind that didn’t work or not as well with DC.
Maybe also work in DC: Plugins for NTFS streams, WebDAV (windows default implementation sucks donkey balls), SCP. I even used it for burning CDs back under XP.
