What is FM1 file?

The file with the extension FM1 is the Spreadsheet Files file type. The creator of this file is IBM. Additionally, the Spreadsheet Files category contains 100 of other files. Lotus 1-2-3 Release 2.x Spreadsheet 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 FM1 file?

An often recurring problem with Lotus 1-2-3 Release 2.x Spreadsheet is that FM1 is not associated with the correct program file. This is manifested by the fact that FM1 files open in unusual applications or do not have an assigned program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the FM1 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. If we do not have this program, it is worth installing it, as it will help you automatically associate the file FM1 with Lotus 1-2-3. Below is a list of programs that support the file FM1.

Programs to open FM1 file

Remember to download programs supporting FM1 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 FM1 files

If the application is or has been freshly installed, but the FM1 file still does not use the Lotus 1-2-3 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. Changes can be made using the "Change" button. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. The "always use the selected program ..." field will set the Lotus 1-2-3 application as the default for handling the FM1 file.

Step 3. Update Lotus 1-2-3 to the latest version

If, despite the association of the Lotus 1-2-3 program with the Lotus 1-2-3 Release 2.x Spreadsheet file, the file still does not open, check the program version and possibly update it to the newest version. 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 FM1 file

The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:

The FM1 file may be unusually small compared to the original file. This is most often caused by a problem while downloading the FM1 file. The only repair option is to download the file again.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file FM1 or the program directory. However, remember that not every infected FM1 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 FM1 files changes over time. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair FM1 file corruption. The easiest way to restore the file is from a backup or by contacting IBM, 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 FM1 files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. These directories are write-protected to them and it's very hard to fix this problem. It is best to move FM1 to a different directory.
This problem usually affects more complex files. In this case, the FM1 file is blocked by the first application to open it. 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.
