Corrupted Mathcad File

[ptc-5159295]

It seems that I have a corrupted mathcad file. I get the following error message when I try to open it. I am using version 15. Is there a way to fix this, I've attached the file.

Can you upload this file?

I tried attaching the file in the first post, and have tried again. Hopefully it works this time. Thanks.

No, it didn't.

You have to click "Use advanced editor" at the upper left first. Then you have at the end of your post the option to attach files.

I have seen this error a few times myself.

It usually happens when mathcad crashes during a save.

If this is what happened then the file will be 0 bytes long (no content) & not recoverable from the file.

However, if you look in the folder where you were trying to save there may be a file in the form "MFCxxnn.TMP" where xx are random letters & nn are random digits.

If there is try renaming it from .tmp to .xmcd .

My experience has been that I can usually recover all the data that I had saved.

Looks like that's what happened, unfortunately no such tmp file, oh well, thanks for the help all.

what if there is not .tmp file created in that folder? How to recover the corrupted Mathcad 5 file then?

[LucMeekes]

Mathcad 5, or Prime 5?

I don't think Prime creates .TMP files. If you attach your corrupted file we can see if it's possible to salvage (part of) it.

Success!

Hey Luc,

I have attached the compressed file of the corrupted .xmcd file. This is the second time this has happened when Mathcad crashes and you are not able to save or save as and the error states ' the requested file is not a valid Mathcad xml worksheet'

[LucMeekes]

Unfortunately, the file is 0 bytes, so has no information to be salvaged.

You should have a backup, or start the file from scratch.

Success!

Hello Maarten,

Hopefully this is what you had.

The highlighted equation is the one that I think had failed, but there are a ery large numer of invalid equations (all showing red) so you will need to check through everything carefully.
