Hi,
i get back and read your first post again :
>> with a AutoCad software now my backup files are saving with out an extension <<
if you mean that .BAK didn't appear then you have from windows explores options select the option for showing file extention.
>> ...and i'm unable to open it. <<
how and why you want open .BAK files ?!!!
please if you still need more help post your need with more details....:)

Hi @Anonymous,
When you open Windows Explorer and browse to a folder, do you see file extensions on your other file types? If not, you can turn on the display of the extensions in Windows>Folder Options
Since you can't normally open a BAK file by double-clicking ti I am not sure there is anything you need to do.
However, I did read that if you search your Windows registry HKCU for .bak and delete the key, that the default will be restored when you logoff and then log back on. I would do this at your own risk and suggest that you make a backup of your registry before attempting this.

Good Morning.
I am having a similar problem. When trying to open by original file I get a pop-up saying "Drawing file is not valid." So I tried to go to Explorer and open the .bak file. I chose open with AutoCAD LT Application. FYI, I'm using AutoCAD LT 2018. I tried searching for AutoCAD DWG Launcher (which is an option I get with I choose open with on the dwg file) but nothing comes up. After doing this I tried making a copy of the file and changing the name and giving it the .bak extension. When I try to open that with AutoCAD LT Appication I get a pop-up that says "Cannot fine the specifice drawing file. Please verify that the network drive is available and the file exists." This all happened this morning. I was working in this file, I saved it, and then closed it (as well as all the programs I had open at the time)...I had to reset our server. After the reset I tried to open the dwg file and that is when I got the "invalid" pop-up. I am not having trouble opening any other files, just this one. And I tried to open it on a different computer but got the same "invalid" message. This file has a lot of needed drawings in it.
Please help!!
Sincerest thanks for any and all help.

I am going to assume you've not done this yet https://www.ricksdailytips.com/display-file-extensions-windows-10/
Otherwise... Post your DWG file here for others to examine and test.

Also remind everyone where exactly these where stored and when was the last time anyone opened them, using which application.

I have uploaded the .dwg file that is "invalid". This won't let me upload the backup file which I have renamed with a .dwg extension but it still says it is a BAK file in the "Type"column in Explorer.
The last time the .dwg file was opened and worked in (and saved) was yesterday morning (8-11-20 around 9am). I saved and closed the file and closed AutoCAD. I reset our server. When I came back to open the file is when I got the "invalid" message. All my other files are fine, it is just this one that I can't open.
The forum won't let me attach the .dwg file. When I hit "post" I get this message

Try another service, like www.wetransfer.com
upload the file(s) and create a download LINK,
share the link and we will see.
(with no hope in this case, Sebastian)

Hi,
all what you need to know you can read above.. where you can't follow the steps?
Explorer: Turn on the File Extension option
Google for: How do I show file extensions in File Explorer?
Now you can see the file extension of the files and change it to *.dwg
1. It doesn't matter which program a * .BAK extension is linked to.
2. But if you want to change it (for no reason)
then link the extension with the EDITOR
(It can't do anything with the file either, just like AutoCAD)
-Right click on file
-Characteristics
-Open with -> Edit -> EDITOR
Sebastian
