There is no such thing as an NTFS-formatted floppy. Long, long ago (before they were bought by Microsoft) SysInternals used to provide a utility that could format floppy disks as NTFS, purely as a proof-of-concept; the conclusion was that it is pointless to use the NTFS file system on a floppy disk due to the frequent disk access required by the filesystem and due to the tremendous overhead required (drastically reducing the amount of free space available on the disk).
In other words, if you're trying to save hard disk space, using NTFS-formatted floppy images won't help you at all. And, of course, DOS cannot access NTFS-formatted floppy disks so there is no point in trying to use such things with DOSBox.
Why the heck would you want to use compressed images anyway!? If you cannot spare 1.4 MB of hard disk space, you should get a larger hard drive, sir!

P.P.S. In case you haven't noticed, no one else is using colored text. Mr. Leileilol is subtly mocking your style. You are engaging in a highly unconventional practice that is making your posts more difficult to read, and you should stop doing that.
