It's a 720k Disk labelled - with what appears to be an mdv label - "QL/MS-DOS v4.0x". It's content is in MS-DOS format and it contains these files:
The readme.txt file it contains contains the following, but doesn't reveal much:

This document covers topics not included in MS-DOS printed documentation.
It also lists a small number of corrections.
ANSI.SYS--INSTALLABLE DEVICE DRIVER
Device drivers are programs that let the operating system recognize devices
that are not a part of the computer (for example, a modem, printer, or
mouse). Some device drivers are already installed with MS-DOS. Other
device drivers, called installable device drivers, can be installed as you
ANSI.SYS, an installable device driver, lets you use ANSI escape sequences
in real mode. An ANSI escape sequence is a series of characters developed
by the American National Standards Institute. You use these escape
sequences to define functions for MS-DOS. Specifically, you can change
graphics functions and affect the movement of the cursor.
Following is a description of two options you can use with the ANSI.SYS
The function of this option is to retain the number of screen rows for
application programs that return the number of screen rows to the default,
25. You change the default with the MODE command.
The function of this option is to prevent ANSI.SYS from using extended
keyboard functions when an enhanced keyboard is installed.
For more information on the ANSI.SYS device driver and the MODE command,
please see the Microsoft MS-DOS User's Reference.
MS-DOS User's Reference--COMMAND command--Page 48.
The second example should read:
If you want to increase space to 256 bytes, not kilobytes.
MS-DOS User's Reference--FIND command--Page 76.
The example should read:
tree /f: | find ".EXE"
MS-DOS User's Reference--MODE command--Page 100.
The second syntax statement should read:
Looks like all normal MS-DOS files to me. I can see no QL connection (apart from the label which looks Digital Precision in style) or am I missing something?
