'ZDNET Recommends': What exactly does it mean?
ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.
When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNET nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.
ZDNET's editorial team writes on behalf of you, our reader. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services. Our editors thoroughly review and fact-check every article to ensure that our content meets the highest standards. If we have made an error or published misleading information, we will correct or clarify the article. If you see inaccuracies in our content, please report the mistake via this form.
The Google Drive app on Android makes it possible for me to manage collaboration efforts while on the go. From that app, I can share files with collaborators, upload and download files, and more. Given how much I collaborate, it should come as no surprise that I put the app through its paces.
Most of the time, Google Drive behaves as expected. Every now and then, however, it acts up and I'm reminded that there's a simple solution to that poor behavior… increasing the Google Drive cache size.

Unless you're dealing with larger files or even working with smaller files throughout the day, you might not ever experience a problem. But for those who do push the Google Drive app to its limits, this handy trick will be just what you need to keep it running smoothly.
Let's do just that.
What you'll need: The only things you'll need are an Android device and the Google Drive app installed. Since Google Drive is installed by default on most Android phones, you should be ready to go.
The first thing to do is open the Google Drive app from either the Android App Drawer or your home screen.
From the Google Drive main page, tap the three-horizontal line button near the top left.

Then, from the popout sidebar, tap Settings.
Near the bottom of the page, locate and tap the Cache size entry.
In the resulting popup, increase the cache size from the default 250 MB to either 500 or 1000 MB. Once you've done that, you can then back out of the Settings app.

To do this either tap the left-pointing arrow at the top left or close the Settings app by swiping up from the bottom of the screen and then dragging the Settings app up to dismiss it.
You should now be able to use the Google Drive app without issue.
Hopefully, increasing the Google Drive app cache did the trick for you and the software is now behaving as expected. If not, there's one more thing you can do. Back at the Google Drive Settings page, just above Cache size, you'll see the Clear cache entry. By tapping Clear cache (and then tapping OK when prompted), you remove all of the cached items being held by the app. There could be cached data within the app that's causing the problem.
