It’s never a bad idea to remove your personal information from a file before sharing it. Office applications might store personal information in each file you create, meaning everyone that receives that file will have your information. Here’s how to remove it.
Save a Copy of Your File
First things first; if you plan to remove any of your personal information from a file, you might not be able to restore the data once it’s gone. With that in mind, it’s a good idea to have a backup file on hand. In addition to having a copy of your original document, be sure to give it a distinguishable name, so you know which file is which.
For example, you might have a slideshow that you presented at a sales conference. After the conference, you may need to send that presentation out to your clients. In this case, you would want to make a copy of the original file and then remove your personal info from the client copy. You’d also want to make sure you don’t send out the wrong copy, so give it a clear name!
Once you’ve saved a copy of your file, open it up and remove your information.
Inspect Your Presentation to Remove Personal Information
Once you’ve opened the copy of the file you’d like to remove your information from, select the “File” tab. Once selected, you’ll automatically be at the “Info” sub-tab. Here, click the “Check for Issues” button.
Select “Inspect Document” from the menu that appears.
