Question

Mathcad File suddenly corrupt and giving message "The file type is not supported. Log file is located at...etc"

After working on a Mathcad file for more than 2 months and for a design job I am doing, I tried to open the file today, but it won't open at all.

I tried from several computers.

Every time I get a message saying:

The file type is not supported. Log file is located at...etc

I have not updated the tile type. So obviously the software corrupted the file last time it was saving it or so.

Now how do I retrieve 2 months worth of work?

I was going to negotiate with my management to upgrade to a paid version of Mathcad and use it as the standard tool for all our calculations. But now I don't trust it.

Please advise how to retrieve the file contents.

thanks

I understand that you're using Prime Express.

You supplied ony the .log file. That is of little use to retreive the Prime sheet.

Note that the .mcdx file is essentially an archive file.

Create a copy of the .mcdx file and change its type (file extension) to .zip.

Now you can open the archive and inspect its contents, maybe you can find the 'corruption' yourself. If not, maybe this community can help, if you (are allowed by your company to) attach the .mcdx or the .zip file.

Success!

P.S. In two months of work you should have some backup(s).... that is if you abide by the 11th commandment "Thou shalt make backups."

This has come up several times before. In all previous cases the file has been completely destroyed. If you are allowed to post it here we'll take a look, but not with much hope of a solution.

    You can also send your issue to PTC's technical support by using "Mathcad Support Center" (you can do it, even if you use Express version of Prime):
