PRT1 file extension - Aldus Persuasion 1 slide

What is prt1 file? How to open prt1 files?

File type specification:

Document file type icon Document file type

The prt1 file extension is associated with Aldus Persuasion 1, a very old application for Macintosh used for presentations, developed by Aldus Corporation, which was later acquired by Adobe Systems.

The product is discontinued and no longer supported.

This prt1 file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.

Help how to open:

Use Aldus Persuasion to open *.prt1 files.

How to convert:

As far as we know, this .prt1 file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
