Corrupted File Need help Mathcad Prime 10

[BM_13564243]

As the title says one of my files got corrupted and i don't know how to recover it i've tried converting it into zip and recover it with some tools found online but nothing works 

This file is important as it contains the contents of a important project that i have to turn in in a couple of days

The problem started today as my Mathcad wasn't starting and then i saw a thread about deleting user config i did and it worked Mathcad was starting and most of the files are available but this one isn't

Please help me I'm quite desperate even tough its not much i already continued with the results from the equations in this and I'm not sure i can replicate them

Try to put the worksheet in a zip or rar archive and attach the archive.

EDIT: Just noticed that you have edited your initial post and added the zip file.

Bad news - the file you posted consists of all zero bytes. There is no information whatsoever which could be extracted.

Hope you have a not too old backup of the file you can work from.

I haven't made any backups and looked into temp also and i found nothing about the file does Mathcad make backups anywhere or is it gone also thank you for answering

To the best of my knowledge Prime doesn't keep automatic backups. Autosave was a feature in good old Mathcad and PTC had promised to implement it in Prime one day or the other, but not yet.

So if you can't find any fragments on your storage device I fear that your work is lost.

The "drumuri 2.mcdx" file  contained in your "drm.zip" file is a file of  346 kB of all zero (0) values. It's essentially empty, there's no information in it.

It seems like you've lost your worksheet. 

Time to grab the latest backup and start from there.

Success!
