Subject: Windows XP thinks my .MAT files are shortcuts`

This is incredibly annoying. I can't email them without zipping or
editing the extension, because outlook will not allow you to email a
shortcut. How can I make XP realize that my .Mat files are NOT
shortcuts? I changed the file association from Microsoft Access
Table to Matlab and it still thinks it is a shortcut...

Thanks,
Bob Ert

Me again.

Actually, even though I changed the file association, XP still tries
to open my .mat files with access when I double click them.

Just curious, why do you want to email a shortcut to your friend? your
friend when they click on the short cut you emailed them, I do not think
they will be able to open the file that the shortcut points to because most
likely they are on a different PC without the file that the shortcut points
to.

Anyway, it is always better to zip stuff up before emailing them. Even if
you are emailing plain text files not just binary data, it will 'protect'
the file from being messed up.

You might want to seek more advanced XP help in
microsoft.public.windowsxp.general newsgroups and specific outlook express
newsgroups.

Bob,
See these two pages:
http://www.mathworks.com/access/helpdesk/help/techdoc/matlab_env/f8-8880.html#bq4h655-1
http://www.mathworks.com/support/solutions/data/1-VW0R7.html?solution=1-VW0R7

Hopefully one of them holds the answer to your question. If not, this
may be something that needs to be resolved through Outlook's
help/support. I am a bit baffled that Outlook would think MAT-files are
shortcuts (whatever application they're associated with); why would they
be shortcuts?

Check out
http://filext.com/

and search for MAT. In addition to being a MATLAB data file, MAT is also
the extension used by Microsoft Access for an "Access Table Shortcut."

Go to your search engine of choice and look up "MAT shortcut access" to find
all kinds of interesting information.

Bob,

I used to have exactly the same problem that you describe. No matter
what I tried, MS Windows would automatically treat my .MAT files as
belonging to Microsoft Access, even when I changed the file
association manually. I no longer have the problem, but I am not
really sure what fixed it. I am currently running Windows XP SP2,
using MS Office 2007, and developing on MATLAB R2007a. This
configuration is working OK for me. My .MAT files are properly
associated with MATLAB now. Since the time when I had the problem
you are experiencing, I haven't changed the operating system other
than to install security patches. I did, however, update my MATLAB
software and switch from Office 2003 to Office 2007. Like I said, I
am not at all certain what fixed the file association problem with
.MAT files, but my suspicion is that one of these software updates
cured the problem.

Good luck,
-Matt

I had the same problem. It was fixed when I upgraded from Matlab
2006a to 2007a. I know TMW fiddled around with Windows shortcuts in
2007a to fix other stuff (e.g., associating fig files with open
Matlab engines etc.), so they must have fixed this at the same time.

You can solve this problem by opening an explorer window, Selectiing Tools->Folder Options->File Types and selecting New. Type MAT in the field, click advanced and select "MATLAB Data" from the pulldown list. You will get a warning that the extension already exists. Click Ok to overwrite it. Problem solved.

Windows XP is probably not what is preventing you from emailing the files.
Depending on what version of Outlook you're using, one of these may apply.

Hello,

I had exactly the same problem (XP SP2, Office 2007, Matlab R2007b) and your trick solved the problem !
Thanks a lot, Craig !

Thanks Craig for this, I have had a different manifestation of the same gremlin...

when using uigetfile my XP profile was filling up !

[datname,datpath] =uigetfile([pwd,'\*filestem*block1.mat'],'Load block1 of data');

after selecting my desired file and clicking on <OPEN> in the dialogue box a file appeared in C:\Documents and Settings\myusername\Recent

The file in Recent showed as filestem_block1 (no .abc after the filename) and the type was microsoft access table shortcut

The file in \Recent was Mb not the usual 1kb for a shortcut and after opening several different (large) files my profile filled up and caused problems with the computer.

Not helpful !!! But thanks to craig
