 Did you know that in Google Drive you can actually manage versions for the files that you upload, for example PDF files or image files? So let me show you. When you are looking at a list view in your Google Drive in a particular folder, you can right click on a file. For example, this PDF file, I want to upload a new version of this. I want to keep the original version just in case. I want to go back to it, look at it, download it, but I can upload a new version so that it becomes the current version. So right click on the file in the list view in Google Drive and then click on Manage Versions. This is really cool. And so you can see the current version was uploaded on Saturday at 3.05 and I have a new version to upload of this PDF file. So I'm going to click on Upload New Version. I go ahead and you might not be able to see this on my computer right now on my screen, I'm going to select a new version that I'm uploading from my desktop. And there it is. The new version has been uploaded. And so I click Close and then when I open up this file, it is indeed showing me the new version of the file. Now if I for some reason wanted to delete the, or look at the other versions, I can go back to list view, right click, or on a Mac it's Control click. Click on Manage Versions and there my original version is, my current version. If I wanted to delete the original version, I can delete it or I can download it. It's really cool. The other thing I want to show you is it works for images as well. So this is an image file and same thing. I can click Manage Versions to upload a new version of the image and do the same thing. So of course this is all, version control is doable with normal files like Google Docs files and Google Sheets, things like that. But this is a game changer in terms of doing it for PDF files and other kinds of uploaded files as well. So I hope this helps. And if you have any other related tips to Google Drive, please go ahead and feel free to comment below. Thanks a lot.
