File type errors may occur due to various reasons. The most common reasons are corrupt or missing files, poorly installed applications, malware infection and registry issues. In this article, we will discuss in detail how to resolve file type errors, such as the .mdb file extension error.
When you encounter a file type error, perform the following steps in the sequence they appear to diagnose the cause and troubleshoot the problem.
Uninstall and reinstall the application
Commonly, a file type error message lists the name of the file that has developed a problem. Write down the name of the file and then use the built-in Search utility to determine if the file is present on your computer or not.
If the required file is reported to be missing or is corrupt, then depending upon whether the file is an application file or a core Windows file, perform either of the actions listed below.
- Application file – In most cases by uninstalling and reinstalling the application with which you are receiving the file type error you can fix the issue of missing or corrupt application files. However, if the file listed in the error message is a DLL file, you may find that the issue persists even after you have reinstalled the application that is generating the error. In such a case, you can resolve the issue by procuring the missing DLL file either by downloading it from a reliable online DLL directory or copying the DLL file from a Windows computer that has a similar configuration as your PC.
- Core Windows file - In case the file listed in the error message is a core Windows file, run the SFC (System File Checker) command to replace the missing or corrupt file. System File Checker is a run time utlity included in Windows that scans Windows protected files and replaces any damaged or missing files from the original Windows installation disc. To run the SFC command, perform the following steps:
Important: To run the SFC command, log-in as an administrator and keep the original Windows installation CD with you, as you may be prompted to insert the installation CD.
- Click Start and then select the Run utility.
- In the Open box, type cmd.
- At command prompt, type sfc /scannow and press Enter.
Use a file opener program to open the file
This is applicable only when you receive a ‘cannot open the file’ or a similar error while trying to open a file. A common cause of such errors is damaged or corrupt file openers on a Windows system. To fix the issue, open the desired file using a reliable Windows file opener program.
Run a malware scan
Malware programs can corrupt your files, such as .pcb files and cause errors. You can fix file errors, such as .pcb file extension errors that are occurring due to virus infection by running a malware scan on your entire computer using a robust protective software.
Perform a registry scan
Another common cause of file errors, such as .pgm file extension errors is a corrupt or damaged Windows registry. To resolve the issue, scan your registry using a reliable Windows registry cleaning software to get rid of any incorrect registry entries and restore the integrity of the data stored in your registry.
