Can Windows 95 read HPFS?
Allan Ballard
Diskeeper does not optimize directory placement, only files within
directories are defragmented.

Not if Microsoft has anything to do with it. But seriously there are Dos drivers for
doing this, they may work under win95, check out hpfsa102.zip, it even
includes a win3.1 driver and writes to HPFS.
Of course with 8.3 filenames :(

That's why I loaded NT4.0 workstation to FAT where it can see files in
the DOS/WFWG partition, and via Pinball.sys,can see HPFS. HPFS in turn
can see all the above as they are in FAT.

I don't belive Win95 will ever support HPFS, because that would mean
Microdaft would have to admit that it works....
As for OS/2 supporting NTFS, I would not be surprised if someone already had
an IFS for it somewhere.....
As for using it....
It stinks! It seems as it has been optimized for creating fragments. I have
been using NTFS on my NT workstation for approx. 6 months(400Mb files on a
1.2GB disk). Most of the installation is static files. I ran Diskeeper lite
on it and it showed me that there was 5 times more file fragments than files
on my disk.......(after running diskeeper the system is a lot faster)

Hi!
I think the solution exists... There are a list of DOS utilities that
able to read/wright HPFS partitions (HPFS386 attr. also supports). I've
looked on my archive to found out the name and placement and: (see
attachments).
Best regards Paul Dolmatov.

Registration information and legal stuff: See the end of this file.
Overview
--------
This program isn't just another program to read OS/2 HPFS drives
under plain DOS. HPFSDOS integrates your HPFS partitions into your DOS
file system!
When invoked, HPFSDOS scans all hard disks for HPFS partitions, assigns
each partition to a new drive letter and stays resident.
Then you can forget you ever loaded HPFSDOS (but please don't forget to
register ;-).
Your programs will work just as if HPFS partitions were DOS drives -
you can list files, copy them and even run them from your HPFS drive
using your favorite DOS tools.
For example, you can use
* A command interpreter, even 4DOS
* DOS programs - Word, Turbo Pascal, Borland C++, dBase, etc.
* Windows programs - Ami Pro, Maple V, Win32s programs, etc.
* Utilities - List, FProt, AMIsetup, Scan, PC Tools, etc.
* Data - ATM fonts, Source code, etc.
Of course, there are some limitations (you knew it, didn't you!)
* Only files with FAT compatible file names (i.e. 8.3) will be listed
[might be improved].
* The HPFS drives are read-only (to protect your valuable data, you
should never use any other program than OS/2 for writing to HPFS
drives) [I don't think this will be changed].
* No support for Extended Attributes.
HPFSDOS is still beta software. However, it has been tested using a
wide variety of software and DOS operating systems. For example,
HPFSDOS will work under MSDOS 3.1, 3.2, 3.3, 5.0, 6.x and Novell DOS 7.
For design reasons, it will not run under DOS 4.x, OS/2 MDOS and
DR DOS 3.41.
Things to watch out for
-----------------------
* HPFSDOS drives claim to be network drives. This is an elegant way to
disable sector editors, DOS checkdisk and other programs that
could crash.
* HPFSDOS drives tell DOS their cluster size was 32 KB. Of course, the
real HPFS cluster size is only 512 Bytes. This lie will allow DOS to
recognize your large 2 GB partitions properly.
* The maximum number of HPFS partitions supported is 20.
* HPFSDOS does not sort directory listings. Try "SET DIRCMD=/OGNE"
instead.
* There is no cache - due to the superior structure of HPFS, access
is still amazingly fast. Any cache program that caches at the
Int 13h level OR at Int 21h level can tremendously improve HPFSDOS
speed (SmartDrive doesn't). HPFSDOS has been optimized to work with
the HyperDisk cache (Shareware by Roger Cross).
* You should set your TEMP and TMP environment variables to point
to a FAT directory, e.g.
SET TEMP=C:\TEMP
SET TMP=C:\TEMP
This will allow many programs to run from a read-only drive.
* Ensure "PagingFile" in Windows SYSTEM.INI points to a FAT drive.
* Some programs (like dBase IV) require the current directory to
be on a FAT drive or else won't run from HPFSDOS drives.
* Free space displayed is always a little higher than under OS/2.
* HPFSDOS eats some of your DOS memory. LoadHigh is recommended.
[Future versions should require less memory.]
* HPFSDOS can read disk cylinders > 1024 if your BIOS supports this.
[Please contact the author if you have problems with this
feature.]
* Drive letters might differ from OS/2.
Use SWAPDRV X Y to swap drive letters (see enclosed
documentation SWAPDRV.DOC)!
Error messages
--------------
* Loading HPFSDOS:
"DOS 3.10 or higher required."
"DOS 4.x not supported."
- Get a new DOS, preferably DOS 5.0 or better
"Your operating system has no CDS support (this program won't run
under OS/2)!"
- HPFSDOS will not run under OS/2 MDOS. You can use the "DOS from
drive A:" feature, however.
"There is no partition table at disk .., sector ..."
"The partition signature might be damaged."
- Please check your hard drive (using NDD or FDISK).
"HPFSDOS supports only 20 HPFS partitions."
"You don't really have that many partitions?"
- Contact the author for a new HPFSDOS version.
"Cannot mount all partitions - please increase LASTDRIVE!"
- To get rid of this problem, add "LASTDRIVE=Z" (or any lower
value which works) to your CONFIG.SYS.
"Drive was improperly stopped. Please run OS/2 CHKDSK!"
- You didn't shutdown OS/2 properly. There might be some
inconsistencies in the file system.
"Detected a (possible) HPFS error. Please run OS/2 CHKDSK!"
- Run OS/2 checkdisk.
* During operation:
"Access denied."
- This is no HPFSDOS error, but a DOS or application error. HPFSDOS
doesn't allow you to create, change or delete files and returns
an "access denied" error code to the application.
"HPFSDOS: Disk read error!"
- Please check your disk (using NDD or a similar tool).
"HPFSDOS: Bad/No ... node!"
"HPFSDOS: ... sector not found!"
- Run OS/2 checkdisk.
Registering
-----------
Developing HPFSDOS has taken much time. I am sure you will recognize
my work, so there are no limitations in the shareware version.
You may try this program for 30 days. If you want to continue using
it, you are expected to register. If you don't like HPFSDOS, simply
DEL it.
>> If you register this version, you'll get:
* Free upgrade to version 1.0 & tools as soon as available
(currently scheduled for July 94).
Version 1.0 will contain:
- performance improvements
- bug fixes?
- new features
The HPFSDOS tools, HCOPY and HDIR, will allow you to display all
files and copy them from your HPFS partitions, with or without
loading HPFSDOS.
HCOPY "E:\AmiPro\Docs\What a long file name.SAM" C:\WALFN.SAM
HDIR E:\AmiPro\Docs
* ... and prices tend to go up rather than down ;-)
>> Please use the enclosed order forms to ensure proper processing of
your order.

*THANK* you for registering AMOS. It is vital that people register
if I am to continue the development of AMOS.
To register AMOS, fill out the registration form at the end of this
document, and send it to the registration site. I prefer to receive
it by netmail, if possible.
Please note that you register AMOS as is and are not entitled to
any upgrades or support. It is most likely that I will continue to
work on AMOS, but it is also likely that any future release of
AMOS will require an upgrade fee (See AMOS3.DOC).
The minimum registration fee for AMOS is US$ 33 or DKK 200 for
non-commercial users. Commercial users must pay US$ 66 or DKK 400

date prices can be obtained by file-requesting or downloading the
latest AMOS v3 version (magic name AMOS3) from my bbs, the phone numbers
of which are listed later in this file.
If the amount is insufficient because of additional transfer
costs or check bouncing, the registration cannot be accepted.

normal circumstances, you will receive your registered copy of AMOS
within two-three weeks after the registration fee has arrived.
AMOS v3 will never be cheaper than it is today.

Their exist DOS device drivers to access HPFS partitions under DOS.
I've tried one wich does work perfect under DOS but doesn't work under
Win95. I don't remember their name right know. May be you can search the
net.
And Allan, I have a (trivial?) question to you: how do I install
pinball.sys under NT 4.0?? Via the registry or something?? I've looked
in the registry of NT 3.51 but could not find how pinball.sys was
included
in the system.

Don't forget Microsquish invented hpfs back in the late eighties (up to
1991) when they were allied with IBM. At the time Dos on a 286 was about the
best they could do for a reasonable price, yuk!!
