Maybe it's confused with FILESHIGH

From: Using MS-Dos7 Commands
http://home7.inet.tele.dk/batfiles/msdos7/

<QUOTE>
Files/FilesHigh
Specifies the number of files that MS-DOS can access at one time.

The FILES and FILESHIGH commands can only be invoked from Config.sys.

Syntax:
FILES=x
FILESHIGH=x
x The number of files that can be accessed at one time. x can be from 8
to 255, with a default value of 30 (Win95) and 60 (Win98).


Notes:
By default, the line
fileshigh=30 (Win95) or
fileshigh=60 (Win98)
is used by Windows on startup. It is only necessary to include a
"fileshigh= " line in config.sys if an alternative value is required
and/or when working without Windows loaded ("pure" Dos mode).

In the days of Dos6 a value of 30 has been recommended as a good general
purpose figure, so 60 should be plenty for most situations. Some Dos
programs such as compilers and databases may require several hundred
files to be open at any time but in such cases the setup program will
likely introduce the required entry in config.sys.

The value set for FILES may not be the only determining factor in how
many files a program can have open at a time, and the design of the
programs being used may be a limiting factor.

Each FILE specified requires about 50 bytes of memory.
If the DOS command is used to manage the upper memory blocks (it usually
is), the default value for FILES are automatically

Thanks. I did mean fileshigh. But according to the web site you linked
there's no difference between the two. So 255 it is I suppose.
Course of action..

DOS prompt then edit C:\config.sys ammend files= to files=255. Is what I
have to do right?

There is indeed no difference in the max number of file handles.

The difference is when FILESHIGH is available and used in the Dos
version that is running it uses upper iso precious conventional memory.

Great.
Do I need to use the FILESHIGH label to make win 95 always boot to 255 tags.
Or once changed to FILES=255 will it always boot to 255?

Thats the last question, honest.

You can use either command to make 255 file handles available. The version
you use simply determines whether the space for the handles is allocated out
of conventional memory or out of extended memory.

Why do you need this many file handles?
