Try right-clicking on the file and then left-clicking Properties. If
that doesn't help, then open the file in Notepad and see if you can
glean any clues from that. If that doesn't help, just delete it and
move on.

Do a Google search for the prefix portion of the filename; might find out something about it.
 
DirectCD Scandisk recovered files, but didn't recovered the file names. It
gave them all a rec extension.
 
Some files are so big that they hang the Notepad. Not all files have the
Properties.
IsoBuster determines the file types but of files recovered by IsoBuster, not
by DirectCD Scandisk.
 
The files were recovered by DirectCD Scandisk. The Scandisk gave them all
the rec extention and a serial number as a file name.
 
Many of those files will be fragments and you may not be
able to use them. Suggest you contact Roxio tech support.

You may also need the services of DriveSavers or similar
file recovery firm.

Most of them are not fragments, but whole files. IsoBuster can recognize the
file type of the files it recovered by itself. Could I use IsoBuster somehow
to determine the rec file type?
 
Well, you could try different extensions to see what you
get, you should have some idea of what file types you had.
Start with .doc, mp3, what ever types you expect to recover.

You don't care about .exe or .dl files because you can get
those from installation CDs.

DirectCD scandisk is for CD-RW disks, but are you trying to
recover files on a hard drive? If it is on a CD-RW, why not
just make another from the original source?

I'm not trying to recover files on a hard drive. The files were recovered
from a CD-RW but without their file names. The files are on a CD-RW now too.
There's no the original source. I saved files on the CD-RW to work with the
files on home and office computers.
 
If you try to open the files within a program, open WORD and
use the file/open menu to select files, will they open? You
should what types of files were saved originally, it may
take a while, but if you can open a file with a program
successfully, you would know the extension and could rename
each file one at a time.

I understand Russian winters are long and very cold. It
could take all winter, if you have 100 files and 5 expected
program types, you have a million or so trial and error
options.


I don't know any other way to do it, it really seems like
the files are gone, short of national security resources to
recover the files. Perhaps you can find some former KGB
types.

There are 764 files on the CD. Half of them are files of program
installation packages, but I don't know which of the files. I can't
distinguish them from files created by me. If IsoBuster can sort out the
files, it is possible to sort out by another program.

I really think you are screwed. The installation files must
be available to each program properly. I think it will be
cheaper and certainly easier to buy new program media to
recover the lost programs.

As far as your files, you might be able to find them OK
because they won't likely be calling on a series of linked
files to work.

If you have a $1,000 or so (US) you could send the CD to
Drivesavers. You can ask them what they think about your
problem at http://www.drivesavers.com

I don't care about the installation files. I want to filter them out from my
files, some of them were zip files.

But the links inside the files, to other files are also
trashed. So you have no way to determine which files you
want to keep, short of trying each file with every program
that you think was used, until you find YOUR files.

You might filter by size, since your files may be small than
the others, but that is just a guess. Perhaps you can ask a
university computer department for help, there must be some
very smart computer people somewhere near you.

Anyway, I have expended all my advice, good luck.

You could dump the first few hundred bytes of the file to examine the header
area. Most file types have a distinctive "signature" within this area. For
instance, a typical exe (or dll) file has the pattern 5A4D in the first
byte, a .pdf file has %PDF in the first word, and a .wav file has RIFF for
its first word. You could compare known files with the unknowns and match
up most of them. Some of the more difficult ones would be those that don't
have an ASCII signature.

I would use a program like 'hd' (hex dump) or 'od' (octal dump) and pipe it
to MORE. If you don't have such a program, I could give you my 'hd' source
code where you could compile it for your platform. If you don't know how to
do that, I have a binary version that was compiled for Windows. Just send
me an email and I'll forward whichever you prefer.

Thanks!
I have Code-Genie v3 installed. Should I use it?
How to dump only the first few hundred bytes of the file?
How to know the distinctive "signatures" for all known files?
 
I took a look at Code-Genie and it does have the capability to show/edit the
binary data. However, they don't show the ASCII form alongside the binary.
Here's an exe example of what I'm talking about:

C:\Windows> hd explorer.exe | more
0000000 00905a4d 00000003 00000004 0000ffff MZ..............
0000010 000000b8 00000000 00000040 00000000 ........@.......
0000020 00000000 00000000 00000000 00000000 ................
0000030 00000000 00000000 00000000 000000e8 ................
0000040 0eba1f0e cd09b400 4c01b821 685421cd ........!..L.!Th
0000050 70207369 72676f72 63206d61 6f6e6e61 is program canno
0000060 65622074 6e757220 206e6920 20534f44 t be run in DOS
0000070 65646f6d 0a0d0d2e 00000024 00000000 mode....$.......

The bytes are numbered like this:
3 2 1 0 7 6 5 4 11 10 9 8 15 14 13 12
and the ascii reads left-to-right. This is standard hex dump format.

The first two bytes are 4d and 5a; their ascii equivalent is the M (4d) and
Z (5a) shown on the same line. There are 16 binary bytes per line and 16
chars per line.

There is an editor called EditPad Pro (not free) which will allow you to
edit the binary and ascii sections, and its display format is identical to
'hd' shown above if you prefer to use an editor. The first two bytes (5a4d)
identify this file as exe format, along with the standard string in all
exe's saying it's not a DOS program. You can try it with your editor, but
it's just easier and faster if you can see the ascii at the same time. I
only suggested 'hd' because I wrote it and it won't cost you anything.

If you use an editor, don't worry about trying to extract only the first few
hundred bytes. Just open the file and look at the header area. If you use
a command-line tool like 'hd', you need to pipe it to MORE to pause it.
Right? That's what I meant by "dump the first few hundred bytes."

Every file type has its own unique way of identifying itself and there are
too many to list. I suggest you look at one of your unknown files and try
to match it up with another file you know about. If you examine an unknown
file and it has the "5a4d" signature, you will know it is an exe file. Does
this make sense to you?

- Robert -
 
Yes. This makes sense.
Please, send your 'hd' binary version that was compiled for Windows to my
(e-mail address removed).
