DAT files attached to emails - why I can't open them?

Adobe 9 says that it might be the coding that is wrong — it's what and how to fix it? Have tried to use other programs, but without success

You don't have a program on your system to open a .dat file and you will not be able to get one or the other because it can be actually any type of file.  In some cases, you can open them if you know the actual file type, and in others you can open them if you use the same e-mail program AND you are the original sender!  It's a problem without a clear solution, other than trial and error with best guess (or, contact the sender to find out exactly what it was attached).

If the file is winmail.dat, then it is caused by e-mail programs used.  Here's the info on it: http://facstaff.gpc.edu/~jbenson/resource/winmail.htm.  This sometimes happens with attachments in e-mail programs, especially when each person uses a different e-mail program (or with some programs in particular as Yahoo mail email).

Here is an article on the opening of the .dat files: http://www.addictivetips.com/windows-tips/open-dat-file-extension-in-windows-quickly/.  It boils down to determine what was the original program who made it and what was his type of original file (so you can change it and use the right program to open the file).  One way is to ask the sender of the email is what the .dat file - they can give you all another name of file and then you know and can just change the extension, convert the file or get a program to open this type of file.

Here is another article on how to open .dat files in Vista: http://www.online-tech-tips.com/computer-tips/how-to-open-dat-files/.  He said much the same as the previous article, but provides some additional information and advice to find the correct file type.

Here's a third article on opening the .dat files: http://pcsupport.about.com/od/fileextensions/f/dat-file.htm.  Among other things, he suggested to try Notepad first, since this program opens up a lot of files and maybe .dat file text.

From your post, it seems that this is not an Adobe PDf file - it is one down.

I hope this helps.

  • why I can't open a link to a PDF file in a new tab?

    I want to click on a link in an email that I was sent just to my teacher after his seminary, which is supposed to open a PDF of the info. But when I right click on it and select open in a new tab, only a white page! But, since I KNOW there must be a correct link, I've tried around and found another way: if I select, "save link as", a window appears and allows me to save it as an adobe PDF file in my computer drive, I can then open and read. Why?
    I mean, what could be the problem? I have never had a problem before you no longer can something right click and select "Open in new tab" and make it work just that like, without the extra steps!

    A link can have several different handwritings in the annex that replace the normal behavior. It is actions that occur when you click (mouse down followed by mouse) a mouse button is pressed on the link (the mouse down) or when he is released on the link (the mouse upward). Usually the right click > open in new tab/window those who will bypass.

    However, in some cases, when you hover over a link you sometimes see that she has no destination address, or seems to be pointing to the same page or starts with javascript:. In these cases, the right click operation fails because it copies this link does not exist or dysfunctional instead of running the script attached to the link.

    Compacted Outlook Express and save some of my emails.  Now, I need access to the following, but can not open them.  How to reopen these emails?

    Hi Redtiger1705,

    Lost emails immediately after compact preforming?
    If so, Outlook Express creates BAK files before compaction. They are copied there as a precaution, in case something goes wrong with the compaction. The following steps should help those rear:

    1) open Outlook Express and go to tools, Options, maintenance, store folder. Copy the entire path to the storage folder, and then click OK.  Close Outlook Express.

    (2) go to the basket and search for all files with the .bak extension.  Restore the most recent .bak files. That he will put in the OE store folder, but still like a BAK file.

    (3) click on start, run and paste the path that you copied in step 1 in the run box, and then press ENTER.

    4) click Tools, Folder Options. In the Folder Options window, click the view tab.
    (5) less advanced, uncheck the "Hide extensions for known file types".
    (6) you should see the two sent a Sent Items.dbx from the file as well as the Items.bak. Rename the Sent Items.DBX to Sentold.dbx and Rename Items.Bak sent to Sent Items.DBX. When you open OE, your messages sent items must be restored.
    Please let me know if I can be of further assistance!
