Question 1

What is Cloud Combo?

Accepted Answer

Cloud Combo is a multi-cloud storage manager that allows you to connect, manage, and transfer files between different cloud storage providers from a single unified platform. We support Google Drive, Dropbox, OneDrive, pCloud, and any WebDAV-compatible storage such as Nextcloud, ownCloud, Synology NAS or Koofr. You can browse files, transfer data between providers, upload, download, and delete files across all your connected accounts without switching between different apps.

Question 2

How do I get started with Cloud Combo?

Accepted Answer

Getting started is simple: 1) Create a free account at cloudcombo.app, 2) Connect your cloud storage accounts (Google Drive, Dropbox, OneDrive, pCloud, or a WebDAV server like Nextcloud) using secure OAuth 2.0 authentication — WebDAV servers connect with your server URL and an app password, 3) Start managing and transferring files between your connected accounts. The entire process takes less than 5 minutes.

Question 3

Which cloud storage providers does Cloud Combo support?

Accepted Answer

Cloud Combo supports Google Drive, Dropbox, OneDrive, pCloud, and any WebDAV-compatible storage — which covers Nextcloud, ownCloud, Synology NAS, Koofr and many other self-hosted or specialist services. Each provider is fully integrated with support for file browsing, transfers, uploads, and downloads. iCloud Drive, MEGA, and Amazon S3 are on our roadmap.

Question 4

Does Cloud Combo work with Nextcloud, ownCloud, Synology NAS or Koofr?

Accepted Answer

Yes. Cloud Combo connects to any WebDAV-compatible storage, which includes Nextcloud, ownCloud, Synology NAS (via WebDAV Server), Koofr, and most self-hosted file servers. Choose the "WebDAV / Nextcloud" tile when adding a drive and enter your server URL, username, and an app password. Once connected, the drive works like any other: browse files, upload and download, and transfer files between it and Google Drive, Dropbox, OneDrive, pCloud, or another WebDAV server.

Question 5

Do I need to install any software to use Cloud Combo?

Accepted Answer

No installation is required. Cloud Combo is a web-based platform that works directly in your browser. Simply visit cloudcombo.app and sign in to start managing your cloud storage. We are developing iOS and Android mobile apps which will be available in Q1 2026.

Question 6

How does Cloud Combo transfer files between cloud storage providers?

Accepted Answer

Cloud Combo uses server-side transfers, meaning files move directly from one cloud provider to another through our secure servers. You don't need to download files to your device first. This is much faster and doesn't consume your local storage or bandwidth. We use streaming technology to handle files of any size efficiently, and our background job processing ensures transfers continue even if you close your browser.

Question 7

Can I transfer folders between cloud storage providers?

Accepted Answer

Yes, Cloud Combo fully supports folder transfers. When you select a folder for transfer, we automatically transfer all files and subfolders within it while preserving the complete folder structure. The hierarchy and organization of your files are maintained exactly as they were in the source cloud storage.

Question 8

How long does it take to transfer files?

Accepted Answer

Transfer speed depends on several factors: file size, number of files, source and destination cloud providers, and current server load. Small files (under 100MB) typically transfer in seconds, while larger files may take several minutes. You can monitor real-time progress for all transfers in your Transfer List dashboard.

Question 9

What happens if a transfer fails?

Accepted Answer

Cloud Combo includes built-in retry logic. If a transfer fails due to network issues or temporary provider outages, we automatically retry up to 3 times. You'll receive detailed error messages if a transfer cannot be completed, and you can retry failed transfers manually from the Transfer List. Our system logs all transfer attempts for troubleshooting.

Question 10

Can I transfer files from Google Drive to Dropbox?

Accepted Answer

Yes, Cloud Combo supports transfers between any combination of connected providers. You can transfer files from Google Drive to Dropbox, Dropbox to OneDrive, pCloud to Google Drive, Google Drive to Nextcloud, or any other combination — including between two accounts of the same provider. Simply connect both accounts, select your files in the source drive, choose the destination folder, and start the transfer.

Question 11

Is there a limit to file size or number of files I can transfer?

Accepted Answer

Cloud Combo is currently free with no monthly data traffic limits — you can connect unlimited accounts and transfer as much as you need. Individual file size limits are determined by the destination cloud provider's API limits (typically 5GB or more for most providers).

Question 12

Is Cloud Combo secure?

Accepted Answer

Yes, Cloud Combo is built with enterprise-grade security. We use OAuth 2.0 authentication, which means we never store your cloud storage passwords. All data transfers are encrypted using SSL/TLS. We don't host or permanently store your files on our servers - files are streamed directly between your cloud accounts. Our infrastructure is regularly audited for security vulnerabilities.

Question 13

Does Cloud Combo store my files?

Accepted Answer

No, Cloud Combo does not permanently store your files. We use streaming technology to transfer files directly from one cloud provider to another through our servers. Files are only temporarily in our system during active transfers and are immediately deleted once the transfer completes. We only store metadata (file names, sizes, transfer status) necessary for providing the service.

Question 14

Can Cloud Combo access my cloud storage files?

Accepted Answer

Cloud Combo can only access files in your connected cloud storage accounts when you're actively using our service. We request minimal permissions necessary to perform file operations (read, write, delete). You can revoke Cloud Combo's access at any time through your cloud provider's security settings. We never access your files without your explicit action.

Question 15

How do you handle my authentication credentials?

Accepted Answer

We use OAuth 2.0, the industry standard for secure authentication. This means you log in directly through your cloud provider (Google, Dropbox, etc.), and they provide us with an access token. We never see or store your cloud storage passwords. Access tokens are encrypted and stored securely in our database, and they can be revoked at any time. For WebDAV servers (like Nextcloud), you provide an app password instead — it is stored securely, sent only to your own server over encrypted HTTPS, and we recommend using a dedicated app password you can revoke rather than your main account password.

Question 16

What file operations can I perform with Cloud Combo?

Accepted Answer

Cloud Combo supports comprehensive file operations: browse and search files across all connected cloud drives, upload files from your computer to any connected cloud storage, download files from any provider to your device, delete files and folders, create new folders, transfer files between different cloud providers, rename files and folders, and manage file permissions. All operations are performed through a unified interface.

Question 17

Can I search for files across multiple cloud storage accounts?

Accepted Answer

Yes, our unified file browser allows you to search within each connected cloud account. While currently you search one account at a time, we're developing a global search feature that will let you search across all your connected accounts simultaneously. One exception: WebDAV drives (like Nextcloud) don't offer server-side search, so search is unavailable for those.

Question 18

Does Cloud Combo have a mobile app?

Accepted Answer

Mobile apps for iOS and Android are currently in development and will be available in Q1 2026. The mobile apps will include all features of the web platform: file browsing, transfers between providers, uploads, downloads, and file management. Until then, you can access Cloud Combo through your mobile browser.

Question 19

Can I schedule file transfers?

Accepted Answer

Scheduled transfers are not currently available but are on our roadmap. This feature will allow you to set up recurring transfers (daily, weekly, monthly) and schedule transfers for specific times. We expect to release this feature in Q3 2026. You can request early access to beta features through our Feature Requests portal.

Question 20

How much does Cloud Combo cost?

Accepted Answer

Cloud Combo is completely free right now. Every feature is unlocked for everyone: unlimited cloud accounts, multi-cloud transfers, uploads, downloads, and file management. No credit card required.

Question 21

Will there be paid plans in the future?

Accepted Answer

We may introduce paid plans for heavy usage in the future as the service grows. Early users will be notified well in advance, and we intend to keep a generous free tier. For now, enjoy everything for free.

Question 22

What technology does Cloud Combo use?

Accepted Answer

Cloud Combo is built with modern web technologies: Next.js and React for the frontend, Supabase (Postgres, Auth, Edge Functions, and Realtime) for the backend, and a dedicated Node.js worker for cloud-to-cloud transfers. We use official cloud provider APIs and OAuth 2.0 for all file operations - your files transfer directly between your own cloud accounts.

Question 23

Does Cloud Combo have an API?

Accepted Answer

A public API is on our roadmap. It will allow developers to integrate Cloud Combo's multi-cloud capabilities into their own applications, with programmatic file transfers, file browsing, and account management.

Question 24

What browsers are supported?

Accepted Answer

Cloud Combo supports all modern browsers including Google Chrome (recommended), Mozilla Firefox, Safari, Microsoft Edge, and Brave. We recommend using the latest version of your browser for the best experience. Internet Explorer is not supported. The web app is fully responsive and works on desktop, tablet, and mobile browsers.

Question 25

Can I use Cloud Combo for business or enterprise use?

Accepted Answer

Yes, Cloud Combo is suitable for both personal and business use, and currently everything is free — including unlimited cloud accounts. We're considering enterprise features including team accounts, admin controls, audit logs, and SSO integration. For business inquiries, contact us at enterprise@cloudcombo.app.

Question 26

Why can't I connect my cloud storage account?

Accepted Answer

Common connection issues include: using incorrect credentials, not granting all required permissions during OAuth flow, third-party cookies being blocked by your browser, firewall or VPN interfering with the connection, or temporary API issues with the cloud provider. Try clearing your browser cache, disabling browser extensions, or using an incognito/private window. If issues persist, contact support with your account email.

Question 27

My transfer is stuck or not progressing. What should I do?

Accepted Answer

First, check your internet connection and ensure both source and destination cloud accounts are still connected. Try refreshing the Transfer List page to see updated status. If the transfer remains stuck for more than 30 minutes, you can cancel and retry it. Check if the cloud provider is experiencing outages at their status page. For persistent issues, contact support with your transfer ID.

Question 28

How do I disconnect a cloud storage account?

Accepted Answer

To disconnect a cloud storage account: 1) Log in to Cloud Combo, 2) Navigate to the Cloud Manager page, 3) Find the account you want to disconnect, 4) Click the disconnect/remove button. This will revoke Cloud Combo's access to that account. You can also revoke access directly through your cloud provider's security settings (Google Account Security, Dropbox App Permissions, etc.).
