What is SLDPRT file?

The .SLDPRT file is part of the project. It is used by the SolidWorks software. It is an engineering type (CAD) software. It is mainly based on .SLDASM design files. These in turn may contain other projects called .SLDPRT files. This allows for more dispersed work, especially on large and complex projects. Additionally, these files can be opened in preview mode by other applications. This allows for quick verification without the need to combine projects.

How to open SLDPRT file?

The main problem with SolidWorks Part Format is that the SLDPRT file is incorrectly associated with programs. This is manifested by the fact that SLDPRT files open in unusual applications or do not have an assigned program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the SLDPRT file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install SolidWorks

The first step is to check if the computer has the SolidWorks program installed. To do this, enter the name SolidWorks into the system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file SLDPRT with SolidWorks. Later in this article you will find a list of programs that can open SLDPRT files.

Step 2. Create association of SolidWorks with SLDPRT files

If, despite the installed application, the SLDPRT file does not start in the SolidWorks application, you must create a file association. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can set the program to handle this type. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. Checking the "Always use the selected program ..." box will permanently associate the SLDPRT file with the SolidWorks program.

Step 3. Update SolidWorks to the latest version

If, despite the association of the SolidWorks program with the SolidWorks Part Format file, the file still does not open, check the program version and possibly update it to the newest version. Some applications allow you to update from the program level, and for others you need to download the installer from the SolidWorks Corporation page and install.

Step 4. Check for the following problems with the SLDPRT file

If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:

Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the SLDPRT file. Downloading the file again should fix the problem.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the SLDPRT file that we want to open. However, remember that not every infected SLDPRT file can be recovered, so it is important to take care of regular backups.
Older version of SLDPRT file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular SLDPRT file corruption. The easiest way to restore the file is from a backup or by contacting Dassault Systemes, but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted SLDPRT files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. If possible, you can try to move the SLDPRT file to another location.
This problem only occurs with more complex files. In this case, the SLDPRT file is blocked by the first application to open it. Closing other programs should help. Sometimes it is necessary to wait a while before referencing the SLDPRT file again. However, some background programs may block the SLDPRT file while scanning. If nothing helps, please reset the device.
