the attachment (letter A.dat) was made with
the MacIntosh version of ADOBE ILLUSTRATOR (8.0 I think)

I would like to read this file on a PC machine.
I've tried to open it with ADOBE ILLUSTRATOR (PC version), but it does
not recognize the file.

Is there a way to open it?

Any help would be appreciated

Thanks
Elwood

From Whois.com

DAT Data file
DAT A data file extension used to designate an error message in a inbound
internet email message (Microsoft Exchange Server v 5.0)
DAT WordPerfect Merge Data
DAT Extension used for some MPEG files

I'm gonna say there was a problem with the upload or download of the
attachment, and that's why you can't open it. Macs don't require file
extensions, so maybe asking the sender to append one will help things.

This often happens to me, also, although I have no idea why. Outlook on my
Windows machine at work will frequently "genericize" an attachment with a
.dat extension. Often, I find that if I save it to disk and change the
extension to what I know it should be (.ai, in this case) and then open it
from within the appropriate app, it works just fine.

This doesn't always work for me......but it often does.

Did you rename the extension to .ai?

Yep, did try, but won't recognize it either
(Invalid File format)

I thought the attachment would make it in this newsgroup, but it does
not seems to. (Yeah I know it isn't a binary group)

Anyway, I also posted it to alt.binaries.pictures.utilities
Someone willing to give it a try, I'd appreciate any effort

thanks again

How did you transfer the file from your Mac to your PC?

If you used an FTP transfer, your Macintosh FTP client might have uploaded
the file as a Mac Binary file (data and resource forks munged into one file)
which might spell problems for the PC version of AI.
If this is the case, change the FTP client's upload method to a standard
binary file transfer and try again.

Another transfer method that will avoid any resource fork issues is to burn
a CD with the Mac using the ISO-9660 CD format.

You should also create a very simple illustrator document for the purpose of
your tests.

PS: Sorry, I have only the Mac version of AI, so I couldn't really look into
this issue.

Since the file is small, it was transfered via email. So there should
not be any problems.

thanks for sharing this info, but I don't think it was a transfert
problem.

thanks

Open the file in a text program, like notepad or wordpad, and look at the
information at the top of the file. It should tell you what program was used to
create it and some information on it.
May give you a clue about how to open it.

I'm guessing here, but it's worth a shot.
I compared that file to one I'd backsaved to AI8. Tops were identical except
for the first three lines on yours. There was nothing like it on mine.
Open your file in Notepad and save as a copy and in the copy delete the first
three lines:

|Letter A
TEXTART5| ĸĸĸĸ
|| =nē+ÞÅđÃÃÛ mBIN |?ã|

Save it with an .ai extension and then try to open that file in Illustrator.

Well, what a nice try. It works. Thanks a million.

Still don't understand it was saved as a (.dat) file on the MaxIntosh?

Anyway, it was tricky way to be able to open it in Adobe Illustrator
on a PC

thanks again for the tip

Not too many with Macs even know what a .dat file is, let alone try and

label files for PC.
Must have been a mung-up in the translation that your PC labeled it.

Glad it worked. It was a tip I picked up in a pre-press group. They have a lot
of experience with opening non-opening files or unknown file types.

Ok, what happened was that whoever sent you the file in the mail
attached it using an encoding method that encoded the Mac resource fork
into the file. They most likely used "Apple Single" encoding. What
they should have done was used a method that only sent the data fork.

It may have had the extension added during e-mail. I've run into .dat
before e-mailing files from Macs to PCs.
