The extension SAM identifies documents of the word processor Lotus Word Pro. They can contain text, formatting, fonts, graphics and images as well as macros. These macros may also contain malicious software, so it is recommended to check SAM files from unknown sources.
The file extension SAM was also used by the previous versions of the word processor. However, the format has changed over time, so that compatibility with each other is not given.
Originally the software was developed as Ami or Ami Pro by Samna. It was one of the first extensive word processors. Later, Samna was taken over by the Lotus Corporation and then by IBM, and the name of the application was changed to Lotus Word Pro.
Lotus WordPro is no longer under development, but is still available as part of Lotus SmartSuite.
For Microsoft Office 97, there was a Converter Pack that would enable Word to load newer versions of SAM files. This converter also used the suffix sam.
Most often resolving problems with opening SAM files is very simple. Just install an appropriate program that supports such files. All of the listed programs support SAM files, but may vary in offered function and purpose. Some programs may be capable only of viewing contents of SAM files or offer file conversion options, but may not be capable of editing such files.
It is possible that although a compatible program has been installed on user’s system, it is not used by the system to open it. This may happen because no default application was associated with this type of files. To associate SAM files with given application, select "Open with" from drop-down menu (accessed by right-clicking on the file). Then select from the list the program or application you want to be used to open this type of file. If the Ami Pro applications is not on the list, select "Browse" option in order to manually locate the directory where Ami Pro has been installed.
Sometimes problems with opening SAM files may not lie with the application itself, but can arise due to other causes, such as:
