The 12M file is supported on 1 operating systems. Depending on your operating system, you may need different software to handle the 12M files. Below is a summary of the number of programs that support and open the 12M file on each system platform.
What is 12M file?
The file in the 12M format belongs to the Misc Files category. The creator of this file is IBM. In addition to this file, the Misc Files category includes 6033 related files. Lotus Smartmaster appears on 1 operating systems as a functional file. These systems consist of Windows, although it may occasionally be found on another system, it will be non-functional. It is recommended to use Lotus 1-2-3 to handle this file. This is a program created by IBM.
How to open 12M file?
The main problem with Lotus Smartmaster is that the 12M file is incorrectly associated with programs. Thus, when you open 12M, the program selection wizard or some other program starts. This can be quickly resolved by following the instructions below.
The first thing you should do is just "doubleclick" on the 12M 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 Lotus 1-2-3
The first step is to check if the computer has the Lotus 1-2-3 program installed. This can be achieved by typing Lotus 1-2-3 into the operating system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below is a list of programs that support the file 12M.
Programs to open 12M file
Remember to download programs supporting 12M files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Lotus 1-2-3 with 12M files
If the application is or has been freshly installed, but the 12M file still does not use the Lotus 1-2-3 program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can select the desired program. 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 12M file with the Lotus 1-2-3 application.
Step 3. Update Lotus 1-2-3 to the latest version
The fault may also lie with the Lotus 1-2-3 program, it is possible that Lotus Smartmaster requires a newer version of the program. Some applications allow you to update from the program level, and for others you need to download the installer from the IBM page and install.
Step 4. Check for the following problems with the 12M file
Of course, it may happen that despite the above steps, the file still does not work. File problems can be divided into the following:
The 12M file may be unusually small compared to the original file. This is most often caused by a problem while downloading the 12M file. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Some antivirus vendors also provide free online scanners. For the best results, we will scan the entire operating system, not just our 12M file. However, remember that not every infected 12M file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the 12M files changes over time. 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. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular 12M file corruption. The easiest way is to restore the file from a backup, if there is one, or contact IBM
The program indicates that the file is encrypted or corrupted. The encrypted 12M files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. It is best to move 12M 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. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If the problem persists, restart the machine.
