WINDOWS TIP: Had undeletable folder with I think Unicode right-to-left and trailing characters. Couldn't delete it even PowerShell. Always said doesn't exist. Used 'dir /x' to see folder's 8.3 name, selected it with that, and used rmdir to delete it. Wow what a trick. @JenMsft

Another fun trick you can use to delete files whose names are messed up is to open a handle to that file (or find a process that already has a handle to it, and inject into it) and call NtDeleteFile on it, with the handle value in the RootDirectory field of ObjectAttributes.

interesting. I presume the fileid number is the same from nFileIndexLow/nFileIndexHigh in BY_HANDLE_FILE_INFORMATION?

to open by fileid- open any file on the same volume first- then do a relative file open to that with the file id option and fileid as name
