Steps to reproduce
- Log in to web client
- Upload a Powerpoint (*.pptx) file
- Watch as the file is silently deleted.
or
- Using the Desktop app, copy a Powerpoint (*.pptx) file to an ownCloud folder
- Log in to web client
- Navigate to folder containing the Powerpoint file
- Watch as the file is silently deleted (and receive notice from the Desktop app that the file has been deleted).
I’ve been unable to reproduce this problem with PDF, Excel, Word or graphics files–only Powerpoint.
Expected behaviour
File should remain unless explicitly removed.
Actual behaviour
File is silently deleted with no warnings or messages in the web UI.

Browser log
Given the behaviour seems to be browser agnostic, I’m not bothering with this.
