How to Get 100GB Free Cloud Storage You Can Combine

Updated 7 November 2026 · Standard formula, shown below

This guide shows you how to stack multiple free cloud storage offers to reach a combined 100GB or more, using accounts that can be linked or used together. You’ll need a valid email address (or several) and a bit of patience to sign up for each service. No credit card is required for any of the methods listed.

What You’ll Need

A primary email address (for most sign-ups)
Optional: a second email address for extra accounts on services that allow multiple free tiers
A smartphone or computer with a modern web browser
Time to complete each sign-up (about 5–10 minutes per service)

Step-by-Step

Sign up for a free account on each service below – Start with the ones that give the most space for the least effort. The exact steps vary, but generally you’ll go to the service’s website, click “Sign Up” or “Get Started,” enter your email and a password, and verify your email address.
Claim the free storage bonuses – Some services give extra space for completing simple tasks like installing a mobile app, enabling two-factor authentication, or referring a friend. Do these tasks to maximize your free quota.
Combine the storage using a cloud aggregator or file manager – Once you have accounts with several services, you can access them all from one place. Options include:
- Using a desktop client – Many cloud providers offer desktop apps that let you sync multiple accounts. For example, you can install the Dropbox app and also add a second Dropbox account (if you have one) or use a third-party tool like Mountain Duck or CloudMounter to mount multiple cloud drives as local folders.
- Using a web-based aggregator – Services like MultCloud or Otixo let you log in to multiple cloud accounts and manage them from a single dashboard. You can also transfer files between clouds without downloading them.
- Using a file manager with cloud support – Apps like Solid Explorer (Android) or Files by Google (Android) allow you to add multiple cloud accounts and browse them in one interface.
Organize your files across the combined storage – Decide which files go where. For example, use Google Drive for documents, Dropbox for sharing, and Mega for large media files. This keeps your storage tidy and makes it easier to find things.
Set up automatic backups or syncs – If you want to ensure your files are always backed up, you can set up folder sync between your computer and one of the cloud drives. Many cloud apps allow you to choose which folders to sync.
Monitor your usage – Keep an eye on how much space you’ve used in each service. Most providers show a storage bar in their web interface or app. If you approach the limit, you can move files to another cloud or delete unnecessary ones.

Common Mistakes

Not checking the free tier limits – Some services offer a small amount of free storage (e.g., 2GB) that may not be worth the sign-up effort. Focus on the ones that give 5GB or more.
Forgetting to claim bonus storage – Many services offer extra space for completing simple tasks like installing a mobile app or enabling two-factor authentication. Skipping these means you miss out on free GBs.
Using the same email for multiple accounts on the same service – Most services only allow one free account per email. If you try to create a second, you’ll be blocked or the old account may be disabled.
Not reading the terms of service – Some services may delete inactive accounts or reduce storage if you don’t log in for a certain period. Make sure you understand the inactivity policy.
Trusting a service that promises unrealistic storage – If a site offers 1TB free with no strings attached, it’s likely a scam or will sell your data. Stick to well-known providers.

Tips

Use a password manager – With multiple accounts, it’s easy to forget passwords. A password manager keeps them secure and accessible.
Enable two-factor authentication – This adds security and often earns you bonus storage (e.g., 2GB on some services).
Refer friends – Many services give you extra storage for each friend who signs up using your referral link. This can quickly add up.
Check for student or promotional offers – If you have a .edu email, you may be eligible for extra free storage on some platforms (e.g., Google Workspace for Education).
Use a cloud aggregator to transfer files – Instead of downloading and re-uploading files between clouds, use a tool like MultCloud to move them directly. This saves time and bandwidth.

Troubleshooting

Sign-up fails or email verification doesn’t arrive – Check your spam folder. If it’s not there, wait a few minutes and resend. Make sure you entered the email correctly.
Bonus storage doesn’t appear – Some bonuses take up to 48 hours to reflect. If it doesn’t show after that, contact the service’s support.
Cloud aggregator can’t connect to a service – Ensure you’ve authorized the aggregator to access your account. You may need to log in again or grant additional permissions.
Files are not syncing – Check your internet connection, make sure the cloud app is running, and verify you have enough free space on your device.
Storage shows less than expected – Some services round down or have system files that take up space. Check your usage breakdown in the service’s settings.

Frequently Asked Questions

Can I really combine storage from different providers to get 100GB?

Yes, by creating accounts on multiple services and using a cloud aggregator or file manager, you can access all your storage from one place. The total free space is the sum of all your accounts.

Which free cloud storage services offer the most space?

As of 2024, some generous free tiers include: Mega (20GB), Google Drive (15GB), OneDrive (5GB), Dropbox (2GB), and Box (10GB). However, these amounts can change, so always check the current offer.

Is it safe to use a cloud aggregator?

Reputable aggregators use OAuth and don’t store your passwords. However, you’re giving them access to your files, so read their privacy policy and use a service with a good track record.

Will my free storage expire?

Some services may reduce your storage if you don’t log in for a long time (e.g., 1-2 years). Others may offer permanent free storage. Check each service’s terms.

Can I use multiple accounts on the same service to get more space?

Most services prohibit multiple free accounts per person and may suspend them if detected. It’s better to use different services instead.

Do I need a credit card to get free storage?

No, all the methods described here are free and don’t require a credit card. Some services may ask for payment details only when you upgrade to a paid plan.
