Collaborating in Google Slides presentations can be chaotic if many people are constantly making changes. If someone makes a mistake, the ability to check the version history in Google Slides makes it easy to fix. See how you can do this.
How to check the version history in Google Slides
To get started, open Google Slides in your browser and navigate to any of your presentations. Be sure to make some changes if you have opened a new document. If you do not have any modifications, you will not see anything in the slide show history.
That way, it's time to check the version history in Google Slides. There are two simple ways to control this. The easiest way is to click on the "Last Edit Was" link to the right of the "Help" button in the menu bar.
You can also check the version history via an option in the menu bar, which is located just below the file name at the top of the screen. Go to File> Version History via the menu bar.
You will see two options in the Version History menu. To check for older versions of the Google Slides presentation, select "See Version History". The "Name Current Version" option is something we will discuss in the next section.
Both methods have the same end result - by opening the "Version History" window on the right side of the Google Slides screen. Here, you will see the timestamps for each version of your presentation. Click on any timestamp to check an older version presentation.
Google Slides tends to group specific versions of your presentations. If you make many changes in a short time chronological dιasthma, you will find them in a group in the Version History window on the right side of the screen. To reveal these hidden versions, you must click on the arrow icon to the left of the timestamp.
After doing this, you will see many additional timestamps in the Version History window. This will allow you to easily find and choose the version you need. Just click on the correct timestamp and you're done.
How to rename Google Slides presentation versions
Talking about finding too many versions in Google Slides can make it difficult to find the version of presentation you want, especially if you are working on a large document with multiple partners. This is why you should also consider naming important versions of Google Slides.
Each time you make a significant change to your presentations, you can open the Version History window in Google Slides. Now, click on the three-dot icon to the right of the timestamp.
You will now see a menu next to the timestamp in the Version History window. To rename it, click on "Name This Version".
Enter any name you like. Once you do this, you can either press the Enter key or click anywhere on the screen.
When you have finished naming important versions of your presentation, you should take a look at a feature of Google Slides that allows you to quickly find renamed versions. Open the Version History window and turn the switch to "Only Show Named Versions."
This will only highlight the renamed versions along with the current version of the document.
How to restore old versions of Google Slides
The last step involves restoring old versions of the Google Slides presentation. To do this, first open the Version History window and select the version you need. The fastest way to get the job done is by clicking the yellow "Restore This Version" button at the top of the Google Slides page, right next to the file name.
Alternatively, you can go to the Version History window and click on the three-dot icon next to the name of the correct version. Next, you need to select "Restore This Version".
This will restore an older version of the Google Slides presentation.
