WinHex is an excellent all-in-one data manipulation tool. When I looked opened it in WINE and opened the about box, I saw a conspicuous "Linux detected".
In its "open disk" tool, the interface is changed slightly where you can input a "Linux device path". Running the software as root, it allows you raw access to partitions and data recovery.
I'm sure there are other similar Windows software that does low-level functions that work through WINE too. What's interesting with WinHex is that it has a kind of "Linux mode" and changes the interface.
Any other Easter Eggs found in Windows software that appears to Linux users?
