good afternoon,
By using AutoCAD 2016, I have many files of this type, one of the files a couple of days ago at the opening of the following issued: Drawing file is not valid.

Is there a way to open a file without losing data?

Is the file you're opening an AutoCAD file?  And if not, what kind of file is it?  You could google a way to convert the file into a correct one.  That's not always a guarantee, but there are files that can be converted and saved.  

If not, you'll have to open it in a program that can handle the file type and save it as an AutoCAD type file and hope it opens. If it is a correct file and you get that error, then you've probably lost that entire save. I've had that happen to me in photoshop numerous times and it's a pain in the ass.

Guide below must help you, if not you may always use useful threads below from Internet space, ultimate solution will help you only in case your AutoCAD file is seriously damaged DWG Repair Toolbox

1. Go to Tools --> Options
2. Inside Options go to the “Files” Tab (far left)
3. Inside the files tab go to: “Automatic Save File Location” and see where the autosave files are stored. (mine where stored at C:\Documents and Settings\USERNAME\Local Settings\Temp)
4. Then access that folder and try to find a file with the same file name but different extension. (The autosave files should have a either a .BAK or a .SV$ extension) (if you can’t see the folder, you need to go to Tools --> folder Options --> View --> and Make sure "show hidden files and folders" is SELECTED) .
5. Check the "date modified" of those files, if the date and time makes sense according to when you had the last file crshes, there is a good chance that those files contain the information you need, so there is no need to redraw everything.
6. Change the file extension of the file you think it might be the good one from .bak or .sv$ to .dwg (to be able to change the file extension you need to be able to see it. To do that, on any folder go to Tools --> Folder Options --> View --> and make sure that "Hide extensions for known file types" is UNCHECKED)

If your auto-save feature is disabled, you can enable it in AutoCAD by going to Tools --> Options --> "Open and Save" Tab --> and there make sure that the "Automatic save" on the lower left corner is active and preferably set to every 10 minutes or less. To easily change the time of the autosave feature, use the SAVETIME system variable.
