The PPV file extension can be found in presentations saved in old Pocket PowerPoint for Windows Mobile. PPV files are used for saving and opening presentations in Pocket PowerPoint. If the PPV file was sent to you by someone else, ask this person to resend the file if it has errors. Files may get corrupted during copying. Download the file again if the download was interrupted.
Pocket PowerPoint was released in 2000 as part of mobile Microsoft Office for Pocket PC 2000. PPV files can only be opened by Windows CE devices as support has ceased over the years. PPV files store presentations which may include text, images, transitions and sound effects. They are similar to PPT files but do not support as many features.
To solve PPV file problems, update your software opening presentations to the current version supporting the latest PPV format. Also check if your PPV file is virus-infected by scanning it. You may need to associate the PPV extension with the software in Windows Registry to open unknown PPV files. Many files contain simple text data.
