RaiDrive is a drive-mounting program for Windows, with a command-line edition for Linux. It connects cloud storage, object storage and NAS servers to the computer as drives. Instead of synchronizing a full copy of a remote account, RaiDrive presents it as a drive letter. Files on Google Drive, OneDrive, Dropbox, an S3 bucket or an SFTP server then open in File Explorer and in ordinary applications. The free Standard plan supports up to eight drives and shows advertisements; paid plans add write access to more services, Local Disk mounting, file locking and other tools.
How a mounted drive behaves
To create a drive, click Add, choose a service from the Personal, Business, Enterprise or NAS groups, pick a drive letter and name, and then sign in or enter connection details. Consumer clouds use a browser sign-in, object storage usually uses access keys and NAS protocols need a server address and account.
Once connected, the drive appears in File Explorer, but RaiDrive copies nothing in advance. A file downloads only when a program opens it, and saved changes go back to the remote storage. Disconnecting unmounts the drive while keeping its settings.
RaiDrive reads opened files on demand, so it can play a video stored in the cloud without downloading the whole file first. The player can jump to any point in the timeline.
Supported clouds, buckets and servers
RaiDrive groups its services into four kinds:
- Personal clouds: Google Drive, OneDrive, Dropbox, pCloud, MEGA, Filen, Koofr, Yandex Disk, Mail.ru Cloud and Ulož.to Disk.
- Business clouds: Google Workspace, OneDrive and Dropbox business accounts, SharePoint, Box, DirectCloud, OpenDrive and SugarSync.
- Object storage: Amazon S3, Azure, Google Cloud, Backblaze B2, Cloudflare R2, Wasabi, MinIO and a generic option for any S3-compatible service.
- NAS and protocols: WebDAV, SFTP and FTP, with specific guidance for Synology, QNAP, ASUSTOR, ipTIME and Nextcloud.
An SFTP drive can use a password or a private key, take a server path as the drive root and fall back to a backup address if the first fails.
Drive options
In RaiDrive, read-only mode blocks every change on the drive while still allowing users to open files and copy them out. Drives can reconnect when RaiDrive starts or ask for credentials on every connection.
Advanced options set separate download and upload speed limits, turn off thumbnails to avoid extra downloads and preserve original modified dates. They also check for changes made elsewhere at an interval rather than on every folder view. This speeds up browsing large storage. Paid plans add quick copy, move and delete. These features run the File Explorer operations on the provider’s servers instead of downloading and re-uploading through the PC.
Local Disk and folder mounts
By default a RaiDrive drive appears as a network location. The Local Disk option shows it among devices and drives, like a USB disk, which some applications require. A Private local disk is visible only to the current Windows account. A Public one can be shared over the network, mounted into an empty NTFS folder and connected at boot before anyone signs in.
File Lock for shared storage
File Lock stops other users from changing a file while someone has it open on shared cloud or WebDAV storage. RaiDrive has dedicated handling for Microsoft Office, LibreOffice and OpenOffice, Hancom Office and Adobe InDesign; other programs receive generic handling.
Cache and access control
Transfers in RaiDrive pass through a local cache with separate lifetimes for read and write data. This lets recently used files reopen without downloading again. Connections use TLS/SSL, and the cache can be encrypted. A PIN-based application lock prevents others at the PC from adding, editing or connecting drives.
Process Monitor and AI tools
Because a mounted drive looks like a local folder, AI assistants such as Claude Desktop, ChatGPT, Gemini and Copilot can work with cloud or NAS files through RaiDrive. Mounting read-only, or mounting only one Google Drive or OneDrive folder or NAS path, limits what such tools can change.
Process Monitor, on paid plans, lists files currently open on monitored drives, the Windows process using each one and whether it is reading or writing. This helps find the program blocking a disconnect or causing unexpected transfers.
Plans and license sharing
The plans differ mainly in drive count and which services are writable:
| Plan | Drives | Writable storage | Extra features |
|---|---|---|---|
| Standard (free) | 8 | Google Drive, OneDrive, Dropbox, WebDAV, SFTP, FTP | Ads; others read-only |
| Starter | Unlimited | All personal clouds and protocols | Quick copy, bandwidth control, Process Monitor |
| Individual | Unlimited | Adds business clouds | Adds Local Disk |
| Team | Unlimited | Adds object storage | Adds File Lock |
| Essential | Unlimited | Personal clouds and protocols | Business, object storage, Local Disk and File Lock as add-ons |
The owner can share a paid subscription by adding members by email address. Each member signs in to RaiDrive with that account. Drive lists and settings can be exported and imported on another PC.
RaiDrive on Linux
On Linux, RaiDrive is a terminal tool. Its commands add, edit and remove storage entries, mount and unmount them and sign in to take a license. It supports fewer services than the Windows application.
