I am facing a situation where I have forgotten the password of my own PowerPoint (PPTX) file that contains important business presentation data. Unfortunately, I no longer have access to the original password, and I urgently need to open and edit the file without damaging or losing any slides, images, animations, or formatting. I have already tried some basic methods, but they either failed or warned about possible file corruption. Is there any safe and reliable way to recover or remove a PowerPoint password without data loss, especially when you are the legitimate owner of the file?
