How to open GRP file?

An often recurring problem with SmarterMail Group Format is that GRP is not associated with the correct program file. This causes the file GRP to open by system applications not designed for this purpose, or to display a message that there is no associated program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the GRP 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 SmarterMail

An often overlooked issue is to make sure that SmarterMail is installed on the computer. The easiest method is to use the system search engine by entering the program name SmarterMail in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file GRP with SmarterMail. Below you will find a list of applications that support GRP files.

Programs to open GRP file

Remember to download programs supporting GRP files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of SmarterMail with GRP files

If the application is or has been freshly installed, but the GRP file still does not use the SmarterMail program, it means no association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The displayed window will contain information about the program that supports this type of file. 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. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the GRP file with the SmarterMail application.

Step 3. Update SmarterMail to the latest version

The fault may also lie with the SmarterMail program, it is possible that SmarterMail Group Format requires a newer version of the program. In this case, use the SmarterTools Inc. website or update the program from the application.

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

Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:

The GRP file may be unusually small compared to the original file. This is most often caused by a problem while downloading the GRP file. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. For the best results, we will scan the entire operating system, not just our GRP file. Sometimes virus-infected GRP files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the GRP file. These problems are known and are often very easy to fix using the software developers's website.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular GRP file corruption. The easiest way to restore the file is from a backup or by contacting SmarterTools, but this one can be expensive. Not all damage can be reversed.
When reading, a message appears that the file was encrypted or corrupted. The encrypted GRP 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. While there is usually no problem reading such a file, it may not be possible to save it. It is best to move GRP to a different directory.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the GRP file again. However, some background programs may block the GRP file while scanning. If nothing helps, please reset the device.
