Clean your digital files this spring instead of paying for more storage.

Google Drive, Google's cloud storage service, has over 2 billion active monthly users, according to Google partner Patronum. And if you're one of those people, you might know you're account gets only 15GB of free space. That storage can fill up fast though, and when it does, you'll see a message asking you to upgrade to a Google One plan. But you don't have to spend any money on more storage. Instead, here are some tips on how to free up some room in your digital filing cabinet for free.

We recommend trying these tips on your desktop rather than a mobile device, as you'll have an easier time sorting through and managing files. But we'll walk you through both processes if you have access only to a mobile device.

1. Delete large files first

If you want to keep the majority of your items in Google Drive and Gmail, you can free up space by sorting each service by file size and deleting only one or two large files instead of a few dozen smaller items. Deleting one or two videos that take up multiple megabytes of space is easier than sorting through hundreds of old documents of similar file size to decide which can be deleted.

Delete files by size in Google Drive

Here's how to delete files by size on your desktop.

1. Log in to your Google Drive account.
2. Click Storage in the menu on the left side of the screen.
3. The Storage page should list your files from largest to smallest, but if not, click Storage used on the right side of the screen. The files should now be ordered from largest to smallest.
4. Click on the large files you want to delete to select them. You can select multiple files by holding the Shift key on your keyboard.
5. After selecting the files for deletion, click either the trash bin that appears near the top of the screen, or click and drag the large files to Trash on the left side of the screen. 

However, you're not finished when the items are in the Trash. From there, click Trash on the left side of the screen to go to the Trash menu. Then, click Empty Trash on the right side of the screen, and then click Empty forever.

You can also delete files by size on your mobile device. Here's how.

1. Open your Google Drive app and log in to your account.
2. Tap Files in the bottom-right corner of the screen.
3. Tap Name underneath My Drive near the top of the screen.
4. Tap Storage used. This will arrange your files from largest to smallest. You can select My Drive and then Storage used again to list your files by smallest to largest.
5. Tap the three dots (...) next to the item you want to delete.
6. Tap Remove then Move to trash.

Google says in the app that Items in your Trash are deleted forever automatically after 30 days. But if you want to speed things up and empty your trash now, here's how. 

1. Tap the hamburger icon (three stacked lines) in the top-left corner of the screen next to Search in Drive. 
2. Tap Trash.
3. Tap the three dots (...) in the top-right corner of the screen.
4. Tap Empty trash.

Whether you need to make more space, or just to keep your Gmail tidy, it's easy to make room for storage in the service.

2. Empty your Gmail spam folder

It's easy to forget about emptying your spam folder, and it can take up unnecessary data in your Gmail account. Emptying your spam folder -- and your social or promotions folders -- is another way to make space.

Here's how to empty your Spam folder on desktop.

2. Once you're logged in, click Spam on the left side of the screen. If you don't see Spam, click More and Spam should be in the expanded menu.
3. In your Spam folder, click Delete all spam messages now.
4. Click OK in the pop up.

And here's how to empty your Spam folder in the mobile app.

2. Tap the hamburger icon in the top-left corner of the screen next to Search in mail.
3. Tap Spam.
4. Tap Delete all spam messages now or Empty spam now.

Don't let spam bog down your Gmail.

3. Clean up your Google Photos

Google also includes Google Photos in the 15GB of free storage it gives its users. Photos and videos can take up more space than text-based files, especially higher-quality ones, so it's a good idea to go through and delete old photos and videos to make room.

There's no option to arrange your photos and videos from largest to smallest like in Google Drive and Gmail, so you'll have to go through and delete items manually. You can check how much space a file is taking up by selecting it and clicking the "i" for information from the top menu. 

Here's how to delete photos and videos from Google Photos on your desktop.

1. Open and log in to Google Photos.
2. Scroll your mouse over photos and videos you want to delete and click the gray check mark icon in the top-left corner of the photo or video. Do this to as many photos and videos as you want.
3. Click the trash icon in the top-right corner of the screen.
4. Click Move to trash.
5. Click Trash on the left side of the screen.
6. Click Empty trash near the top-right corner of your screen.
7. Click Empty trash again, and you're set.

And here's hot to delete photos and videos from the Google Photos mobile app.

A note for Apple users: If your Gmail is linked to your iCloud account, the two digital storage spaces may be also linked. This means that when enabling the Backup & sync feature on Google Photos, all your local photos on your iPhone will be displayed on Google Photos. If you delete a photo on Google Photos, then the local photo on your iPhone will also be removed. And when the local photo is removed, it won't show up on iCloud. You'll be able to tell if this is you when you try to delete an image on Google Photos -- a pop-up window will let you know you're about to delete from both places.

1. Open and log in to Google Photos.
2. Tap the photo or video you want to delete.
3. Tap the trash can icon in the bottom-right corner of the screen.
4. Tap Delete. 
5. Tap Library in the bottom-right corner of the screen.
6. Tap Trash.
7. Tap the three dots (...) in the top-right corner of the screen.
8. Tap Empty trash.
9. Tap Delete. 

If you don't click or tap Empty trash on either desktop or mobile, the photos and videos you've deleted will automatically be deleted after 60 days. 

Bonus tip: You can reduce the file size of some photos and videos in Google Photos. Doing so will allow you to regain some space, but it will reduce the quality of your media. You can learn more about this from Google Support here.

4. When all else fails, download your files to your desktop

If your storage is still almost full and you can't part with any more items from your Google Drive, Gmail or Google Photos, you can download your items and store them directly on your computer.

Here's how to download all your Google files for storage on another hard drive.

1. Open and log in to your Google Drive or Google Photos account on your desktop.
2. Select the files or photos you want to download.
3. Click the three stacked dots in the upper-right corner of your screen.
4. Click Download. Note that Gmail will download messages as a .eml file.
5. Once the items are downloaded and moved onto your hard drive, feel free to delete them from your account and empty your trash bins.

You can download emails from Gmail in much the same way, but you have to download your emails one at a time. While this makes downloading your emails more tedious, but still possible. Here's how to download your emails from Gmail.

1. Open and log in to your Gmail account on your desktop.
2. Click into the email you want to download.
3. Click the three stacked dots in the upper-right corner of your screen.
4. Click Download. Your emails will download as a .eml file.
5. Once your emails are downloaded and moved onto your hard drive, feel free to delete them from your account and empty your trash bins.
