Questions and answers

  • What is the purpose of .SNM formats and what types of files can be saved in this format?

    The .SNM format is used for saving slide show presentations in the old versions of the Lotus Freelance Graphics software. Lotus Freelance Graphics was a presentation program that was popular in the 1990s.

    The .SNM format stores the slide show data including the layout, text, images, animations, and other visual elements. It was primarily used for creating and delivering presentations, similar to Microsoft PowerPoint.

    However, it's worth noting that the .SNM format is outdated and no longer widely used. Modern presentation software like PowerPoint, Google Slides, and Keynote have become more popular and support more advanced features.

  • Are .SNM formats compatible with all operating systems and software applications?

    No, .SNM formats are not compatible with all operating systems and software applications. .SNM files are typically associated with the Siemens Notation Machine software, which is specific to Siemens PLC programming. These files can only be opened and used within the Siemens Notation Machine software or other Siemens-related software. They cannot be opened or used with other operating systems or software applications unless they have specific support for .SNM files.

  • How can one convert or open .SNM files if the necessary software or program is not available?

    If you don't have the necessary software or program to open .SNM files, you can try the following methods:

    1. Use a Universal File Viewer: Universal file viewers like File Magic, Free File Viewer, or File Viewer Lite can open a wide range of file formats, including .SNM files. Install one of these viewers and try opening the .SNM file with it.
    2. Change the File Extension: Sometimes, .SNM files may actually be in a different format. Try changing the file extension to a more common format like .TXT, .DOC, .PDF, etc., and then attempt to open it with a text editor or an appropriate program for that format.
    3. Online File Conversion: There are numerous online file conversion services available. Upload the .SNM file to one of these websites and convert it to a more common format like .PDF, .DOC, or .TXT. Once converted, you can download and open it using the appropriate software.
    4. Contact the Sender: If you received the .SNM file from someone, reach out to them and ask for the file in a different format that you can open. Explain the issue you are facing and request an alternative format that is compatible with your available software.
    5. Search for Software: Conduct an online search to find software specifically designed to open .SNM files. There might be specialized programs or converters available that can handle this particular file format.
