What is NSF file format?

The NSF file format, or “Notebook Storage File,” is an open format used to store data in a notebook-style format. The format was originally developed by Lotus Software, now part of IBM, and is designed to store text, graphics, tables, and other data in a notebook-style layout. The NSF file format is similar to a combination of a spreadsheet and a text editor, allowing for both structured and unstructured data to be stored. It includes features such as the ability to link external file attachments, text formatting, and the ability to store information in multiple pages. Due to its versatility, the NSF file format is widely used in a variety of applications, including business intelligence, project management, scientific analysis, and many others. It is also used to store presentation materials such as slides, graphs, and images. The NSF file format is a popular choice for storing large amounts of data due to its compatibility with a wide range of platforms. It can be used on Windows, Mac, and Linux, as well as mobile devices such as smartphones and tablets. Although the NSF file format is not a standard, it is well supported by many popular programs such as Microsoft Excel, Apple iWork, and Adobe Acrobat. Furthermore, the format can easily be converted to other formats, such as PDF, XLSX, and HTML. This makes it a great choice for sharing and archiving documents.

What is POTM file format?

A POTM file refers to a macro-enabled presentation template created using Microsoft PowerPoint, a software program used for creating slide show presentations. It includes default images, slide templates, macros, and formatting. POTM files are commonly used by PowerPoint users to create multiple .PPTM files with consistent designs and macro settings.

POTM files offer additional functionality compared to typical presentation files, as they support macros. Macros are script-like functions that automate repetitive tasks within PowerPoint. Users can record macros that can be replayed to perform specific actions and assign them to buttons or keystrokes for convenient execution. To record a macro, users can select View → Macros in PowerPoint.

For general presentation creation, users can save their files as .PPTX or .POTX files. However, if they want to create a template that incorporates macros, they can save their presentation as a POTM file.

It’s worth noting that POTM files were introduced by Microsoft when they released Microsoft Office 2007.

To open a POTM file, Microsoft PowerPoint (2007 or later) is the recommended application for full support of presentation formatting and embedded macros on both Windows and macOS. Alternative applications like Apache OpenOffice Impress, Kingsoft Presentation, and Apple Keynote can also open POTM files, but some formatting and macros may not be fully preserved. For Mac users looking to view a POTM file without editing, Apple Preview (bundled with macOS) or Google Drive, a free cloud storage service, can be used.

Online platforms like Google Slides allow users to upload POTM files for viewing, editing, and conversion. However, it’s important to note that Google Slides does not support macros.

To convert a POTM file, various presentation applications including Microsoft PowerPoint, Apple Keynote, and OpenOffice Impress offer conversion capabilities. In Microsoft PowerPoint for Windows and Mac, users can select File → Save As and choose from formats such as .PPTX, .PPT, .PDF, .ODP, .XPS, .MP4, .WMV, .JPEG, and .PNG to convert the POTM file to their desired format.
