Data Recovery and Disk Utilities Forum @R-TT

Hello.
I need to recover files .CAE (Abaqus). I have some samples; but I can not obtain a digital signature to incorporate it into R-Studio.
Could someone help me ?.
Thank you!

If they're not large, you may send me them to my mail: raptorbck (at) gmail (dot) com .
If not, maybe some file sharing host?

And I don't need actual (probably) large files. It'll be OK if you create some new with small different content in each.
