SMTMP File Extension

How to open SMTMP file?

After double-clicking on the unknown file icon, the system should open it in the default software that supports it. If this does not happen, download and install the avast! Antivirus software and then manually associate the file with it.

Step 1. Download and install avast! Antivirus

If there is no avast! Antivirus or similar software in the system that supports files with the SMTMP extension, you must first download and install it. Below you will find a list of the most-used applications that work with SMTMP. After going to the subpage of the program you will find a link to the developer's website, where you can safely download the software installer.

Step 2. Associate avast! Antivirus with the SMTMP file extension

If the user already has one of the applications installed, the next step will be to associate it with the file extension SMTMP. This can be done in two ways - one is to manually edit the Windows Registry and HKEY_CLASSES_ROOT keys. The second way is simpler and definitely recommended for less advanced users.

• Right click on the unknown SMTMP file you want to open
• Select "Open with" from the menu
• Click "Choose another application"
• Click "More applications"
• Click "Find more applications on this PC" and indicate the installation location of the appropriate program
• Finally, select the "Always use the selected program to open SMTMP files" option and confirm the whole operation.

Remember! Manually editing the system registry is only recommended for advanced users, and changes made to it without proper knowledge may result in damage to the system.

Step 3. Check out other possible problems related to SMTMP files.

Sometimes it happens that despite having the right application and the correct configuration, there are still problems with opening the SMTMP files. You should then find out what is the reason of the problem.

• Check if the SMTMP file is not infected - When the file SMTMP is infected with a virus or malware, it probably will not be able to be opened correctly. In this case, scan the SMTMP file and take the actions recommended by the antivirus program installed on the system. Most often it is disinfection or deletion of an infected file.
• Check if you, as the operating system user, have appropriate permissions to work with the file SMTMP
• Check if the icon is an element of the correct file but not only a shortcut to the location where the SMTMP file no longer exists.
• Check that the system has the necessary resources to run the avast! Antivirus application and open the SMTMP file.
• Check if the file is complete - Sometimes it happens that the SMTMP file was not copied completely from the external Flash memory, or downloaded from the Internet. When the file is incomplete, it is not possible to open it correctly. In this case, please download or copy the file SMTMP again.

Step 4. Contact an IT expert

When all of the above methods have failed, it remains to contact an IT specialist or developers of the AVAST! ANTIVIRUS program.
