Part 1. 5 Hidden Reasons Behind a Corrupt or Damaged PPTX File
Moving forward, you should first understand the reasons behind file corruption to prevent it before it occurs. By recognizing the hidden factors, it becomes easier to fix PPTX file problems effectively. Thus, let’s dive below to discover the common reasons that can lead to file corruption:

- File Transfers: Interruptions during the migration, such as unstable internet connections or improper ejections of USB drives, may damage file integrity. So, users have to verify file transfers and avoid abrupt disconnections to maintain data accuracy.

After understanding the causes of corruption, it becomes easier to choose an effective solution. PowerPoint offers recovery options, while external methods provide additional ways to restore files. The following section gives you 5 simple PPTX corrupt file repair methods to recover presentations.

Way 2. Move the PPTX File to Another Drive
In case the presentation is still corrupted, the problem may be linked to the storage location. This can happen due to bad sectors on a hard drive, external storage issues, or file system errors.

In addition, a presentation fails to open due to add-ins or software settings conflicts.
