How to open file with RES extension?

Fortunately, most common problems with RES files can be solved without in-depth IT knowledge, and most importantly, in a matter of minutes. The following is a list of guidelines that will help you identify and solve file-related problems.

Step 1. Get the Microsoft Visual Studio

Problems with opening and working with RES files are most probably having to do with no proper software compatible with RES files being present on your machine. This issue can be addressed by downloading and installing Microsoft Visual Studio or different compatible program, such as Delphi, ResEdit. On the top of the page a list that contains all programs grouped based on operating systems supported can be found. One of the most risk-free method of downloading software is using links provided by official distributors. Visit Microsoft Visual Studio website and download the installer.

Step 2. Update Microsoft Visual Studio to the latest version

You still cannot access RES files although Microsoft Visual Studio is installed on your system? Make sure that the software is up to date. It may also happen that software creators by updating their applications add compatibility with other, newer file formats. This can be one of the causes why RES files are not compatible with Microsoft Visual Studio. All of the file formats that were handled just fine by the previous versions of given program should be also possible to open using Microsoft Visual Studio.

Step 3. Set the default application to open RES files to Microsoft Visual Studio

If the issue has not been solved in the previous step, you should associate RES files with latest version of Microsoft Visual Studio you have installed on your device. The process of associating file formats with default application may differ in details depending on platform, but the basic procedure is very similar.

Change the default application in Windows

• Choose the Open with entry from the file menu accessed by right-mouse clicking on the RES file
• Select Choose another app → More apps
• To finalize the process, select Look for another app on this PC entry and using the file explorer select the Microsoft Visual Studio installation folder. Confirm by checking Always use this app to open RES files box and clicking OK button.

Change the default application in Mac OS

• Proceed to the Open with section. If its closed, click the title to access available options
• Select the appropriate software and save your settings by clicking Change all
• If you followed the previous steps a message should appear: This change will be applied to all files with RES extension. Next, click the Continue button to finalize the process.

Step 4. Verify that the RES is not faulty

You closely followed the steps listed in points 1-3, but the problem is still present? You should check whether the file is a proper RES file. Problems with opening the file may arise due to various reasons.

1. Check the RES file for viruses or malware

If the RES is indeed infected, it is possible that the malware is blocking it from opening. Immediately scan the file using an antivirus tool or scan the whole system to ensure the whole system is safe. If the scanner detected that the RES file is unsafe, proceed as instructed by the antivirus program to neutralize the threat.

2. Ensure the file with RES extension is complete and error-free

Did you receive the RES file in question from a different person? Ask him/her to send it one more time. It is possible that the file has not been properly copied to a data storage and is incomplete and therefore cannot be opened. If the RES file has been downloaded from the internet only partially, try to redownload it.

3. Check if the user that you are logged as has administrative privileges.

Sometimes in order to access files user need to have administrative privileges. Log in using an administrative account and see If this solves the problem.

4. Verify that your device fulfills the requirements to be able to open Microsoft Visual Studio

If the system is under havy load, it may not be able to handle the program that you use to open files with RES extension. In this case close the other applications.

5. Check if you have the latest updates to the operating system and drivers

Regularly updated system, drivers, and programs keep your computer secure. This may also prevent problems with C++ Complied Resource Script files. It may be the case that the RES files work properly with updated software that addresses some system bugs.
