With the rapid development of technology, CAD (computer-aided design) has become a powerful assistant in many industries. However, when it comes to designing, you may encounter various problems, the most common of which is the misclick "do not save". This will undoubtedly make all your previous efforts go down the drain and be frustrating. So, how do you recover your files if you accidentally click "Don't Save"?Here are some common tips. 
Tip 1: Take advantage of CAD's auto-save functionMany CAD software has an auto-save feature that can help you recover your previous files within a certain period of time. Usually, this function can be activated in the "Options" or "Settings" section of the CAD software. You can set an auto-save interval in your CAD software, such as 5 minutes or 10 minutes. Once you've done enough in CAD, CAD will automatically save your files on disk. If you accidentally click "Don't Save", you can go back to the location where you saved it, find the auto-saved file, and open it. Tip 2: Make use of backup filesIn CAD design, every time a file is opened, a backup file is automatically created. Usually, this backup file will be named "File Name." bak" in the same directory as the original file. So, if you accidentally click "Don't Save", you can go back to the directory of the original file, find the backup file and open it. Once you have opened the backup file, you need to copy the contents of the backup file to the original file and save it. Tip 3: Take advantage of the history featureIf you are using CAD software like AutoCAD, then you can also take advantage of the history feature of the software to recover your files. In AutoCAD, you can open the history window by clicking on the "History" option in the "Window" menu. In the history window, you can see all the actions you've done on the file, including saving and modifying it. If you accidentally click "Don't Save", you can find the last saved version of the file in the history window and open it. Tip 4: Make use of data recovery softwareIf you have tried none of the above methods to recover your files, then you can also try to use data recovery software to get your files back. Data recovery software can scan your disk and try to get back deleted or lost files. For example, Recuva, Stellar Data Recovery, etc. are more commonly used data recovery software. You can use these software to scan your disk and try to get back your CAD files. 
Tip 5: Ask CAD software technical support for help
If you encounter any problems while using the CAD, including accidentally clicking the "Do Not Save" button, you can ask the technical support of the CAD software for help. Many CAD software offers ** technical support or customer support where you can contact them and tell them your problem. They may offer some solutions or suggestions to help you recover your files. In conclusion, accidentally clicking the "Do Not Save" button when designing with CAD can cost you all of your previous work and be very frustrating. However, by using the methods presented above, you can try to recover your files and continue with your work. If you run into any problems, don't hesitate to ask for help or try other ways to fix the problem.
