Windows – Copying large file to removable media

ms-dossd-cardusb-flash-drivewindowswindows-xp

Using WindowsXP-Pro, I'm trying to copy a largish file (~28 MB) on to an SD Card.

The copy gets almost completed, when it fails and returns with this error:

Cannot copy <filename> file: Invalid MS-DOS function

There's lots of room on the card 120+ MB.
I can copy lots of other smaller files onto the card, so I don't think the media has failed.

Is there something else I've missed?

Try zipping up the file and then copy it. To see if the filesystem or card is somehow corrupt, backup your data, re-format the card, and try again.

By the way, can you copy that file elsewhere on your hard disk? Because if you can't, then the file is corrupt (or less likely, a part of the filesystem).
