mathcad prime 6.0 file recovery

To the best of my knowledge there is no tool to do so.

mcdx files are just zip-files. You may try to rename the file to *.zip and extract its contents maintaining the folder structure. You will see that the archive mainly consists of a couple of xml file, which are editable text files.

If a file got corrupted, chances are that the error is in \mathcad\worksheet.xml. You may try to fix the error by editing this file.

Generally fixing a corrupted file of real Mathcad (xmcd or mcd) is much more promising (and much less often necessary because of Mathcads autosaving feature) as the file is just a single xml file and Mathcad would tell you the line number in the file which causes the error.

We don't have this comfort in Prime and furthermore ever so often people had posted a corrupted Prime file here in the forum and after a quick check it turned out that the file consisted of nothing but null bytes. So there was no information which could be retrieved.

Good luck!

So first check the size of the file.

If it is 0 (zero) bytes in size, than it is really lost.

If it is larger, but contains only values of 0, it is also lost.

In other cases you can do as Werner explains, or you can attach the file, and we can inspect, maybe help you.

Success!

Hi,

It is a good habit when working with such software, to save the worksheets every day with a name different from that of the previous day, adding to the name, for example, the date of the day itself, or a progressive number, so that if you lose the last worksheet, you can always start over with the one of the previous day. Otherwise, in case of file loss, you have to do it all over again. Space occupied, even with this type of saving that lasts for months and months, is negligible compared to today's hard disk capacities. Furthermore, having a continuous backup system eliminates any loss problem. Mathcad 15's autosave is only useful when the file is not lost.
