The PUB file extension is primarily associated with the software “Publisher” from Microsoft Corporation. Microsoft Office Publisher helps you to create, personalize, and share a wide range of publications and marketing materials in a nutshell. It is used to create professional documents and other materials. PUB files are used as documents which are created by the application that contains many vector images, texts, and drawn objects formatted in it. Such files are used for creating various marketing materials like newsletters, brochures, posters, and other documents.
Adobe can also work with PUB documents with PUB2ID plug-in. They can be opened in a read-only mode by the trial version of Microsoft Publisher even though the trial period has ended. Another program that uses the file extension PUB is the “Pretty Good Privacy” (PGP) cryptography application. It uses these files for building a storing public portion of asymmetrical encryption or decryption key.
The PPS file extension on the other hand is associated with the Microsoft PowerPoint, which is known worldwide as a popular powerful tool to create and edit dynamic and great-looking presentations. PPS files are used to complete slide shows, which are very often used at the time of various presentations.

PPS files can include formatted text, bullet points, images, movies, sound effects, or music.

The Microsoft Office PowerPoint 2007 and the later version save presentations in OpenXML format that uses the PPSX extension.
