How Do You Open a SOLIDWORKS File When SOLIDWORKS Thinks the File is Already Open?

EmailFacebookGoogle+LinkedInTwitterShare

We have had several calls with this issue:

SolidWorks crashed with a SOLIDWORKS file open. Now, when you try and open the SOLIDWORKS file after you restart SOLIDWORKS, an error comes up saying SOLIDWORKS cannot open the file. The file is already open.

Obviously, the SOLIDWORKS file is not open. Why does SOLIDWORKS think it is? Well, when SOLIDWORKS opens a file, a temporary file is created by Windows in the same directory as the SOLIDWORKS file. When the file is closed, the temporary file is automatically removed. If SOLIDWORKS does not close properly, the temporary files are sometimes not deleted automatically. What can also make the issue more confusing is that the temporary files are hidden by Windows. 

In Windows Explorer, open the directory of the SOLIDWORKS file. 

SolidWorks_File

As you can see, only the SolidWorks file is shown. To display the temporary files, press the Alt key to show the Tools pull down menu and pick Folder Options.

Folder_Options

In the Folder Options dialog box, on the View tab, pick Show hidden files, folder, and drives and click OK.

Show_hidden_files

You can now see the temporary file. It is the file that begins with ~$.

SolidWorks_Temporary_File

All you have to do is to delete the temporary file. Now, SolidWorks will open the file without any issues.

  1. This didn’t work. I was able to get the ~temp files to show, I then deleted them and I still get the same error message.

  2. I am sorry to hear that this solution does not work for you. Please contact CATI Technical Support and we will be happy to troubleshoot your specific issue for you.
