A .pptm extension file is a macro enabled open XML, Microsoft PowerPoint Presentation file. The presentation pages that are termed as slides comprise of text, images, videos, graphs and other components including media files that are required in a presentation. This feature is especially helpful to create presentations for the academic, marketing and business domains where a large amount of content needs to be stored. The advantage of using the .pptm extension as compared to .pptx is that macros can be executed in files with this extension whereas it is not possible to execute macros in .pptx files even if it has macros in it, apart from that both formats have similar features. Microsoft introduced the Open XML format for PowerPoint presentations in 2007 hence files with this extension cannot be opened with previous PowerPoint versions. However, if a Microsoft Compatibility Pack is installed along with the previous versions, it would be possible to open the files with .pptm extension.
The .ppm file extension is used for Portable PixMap format files and is intended to be an intermediate format that can be used in the development and conversion of other file formats. This format was specifically designed so that it could easily be exchanged between various platforms. It is very simple but not very storage efficient. Before the PPM format was introduced, Jef Poskanzer invented the PBM format in the year 1980 for transmission of monochrome bitmaps as ASCII text in email messages. He also developed a tool library for easy conversion of the PBM files to other graphical formats and vice versa. This library was called Pbmplus and was released in 1988. Later Poskanzer developed the PPM format along with the PGM format and the requisite tools that were added to Pbmplus.

The PPTM format combines the XML Architecture with the ZIP compression technology to reduce the file size. Images, audios and videos can be opened using the 7-Zip application if a compatible PPTM editor or reader is not installed on the system. PPTM files can be converted to other formats that include PPT, PDF, PNG, PPTX or JPG. It can also be converted to a video format like MP4 or WMV. The recent additions to the presentations include features like inserting music that plays all through the presentation, sound effects to highlight specific slides, designing the presentation to play on its own just like a movie, recording the slide show with a pointer on one hand and narration on the other, repetition and shuffling the order of the slides as per requirement.
A .ppm extension file comprises of two parts which include the header and the image related data. The header, in turn, is distributed into three parts that are demarcated by line feeds. The first line comprises of the magical PPM identifier which can either be P3 for the ASCII version or P6 for the binary version, and the next line has the image's height and width displayed in ASCII characters and the last line indicates the maximum color value of the pixels. The image data formatting is dependent on the magical identifier, given in the first line of the header. Each pixel consists of 3 decimal values ranging from 0 to the specified maximum value written in ASCII characters. The 0 in the decimal values denotes that the color is not present or is turned off and the maximum value denotes that the color is at its maximum level. Conventionally the image data is stored in a left to right and top to bottom order with each pixel being stored as a byte. The usual RGB (Red ñ Green ñ Blue) order is followed to store the components.
