Why Mounting Box on Windows Is a Smart Move
Working directly on Box files through File Explorer beats the usual download–edit–reupload dance. A mounted drive streams files on demand through WinFsp, so you can browse a large Box account without filling your PC's SSD. And because the mount is just a drive letter, every Windows app — Office, Photos, VS Code — sees Box as a native location.
- 🧩 Native File Explorer Integration — Your Box shows up as a regular drive in "This PC", so every Windows app can open and save into it without a special plugin.
- 💾 No SSD Hostage Situation — Mounting streams files on demand, so even a large Box account only spends disk space on the files you actually open.
- 🏢 Great for Business Content — Box is built around team and enterprise content management, and a mounted drive lets you work with shared folders straight from File Explorer.
- 🛡️ Read-Only Mode for Safety — Mount read-only when you only need to browse shared or archived files, and Windows will block any accidental write.
- ☁️ 10 GB Free to Start — Box personal accounts start with 10 GB free, with larger business and enterprise plans when you need them.
How Mounting a Cloud Drive Works (and Why It's Different from Sync)
The Box desktop client downloads your files (or stubs) to a folder and keeps both sides in lockstep. That works, but it ties you to Box's own sync engine and its idea of which files to keep local.
Mounting takes the opposite approach. OurClone presents your Box as a virtual filesystem through WinFsp — the folder structure is visible immediately, but file contents are only fetched when you actually open something. Recently used files are cached locally so the second open is instant, and writes are pushed back to Box in the background.
OurClone makes both the polling interval (how often it checks Box for remote changes) and the maximum cache size configurable, plus a read-only switch for extra protection against accidental writes.
- 🚀 Stream files on demand — no need to download the whole drive
- 💾 Saves PC disk space by caching only what you actually open
- 🔁 Two-way sync — edits in the mounted drive push back to Box
- 🛡️ Read-only mode prevents accidental writes when you only need to browse
What to Know Before You Mount Box
A few minutes of planning before you click Mount will save you from cleaning up a messy mount point later.
- 🧩 Install WinFsp First — Mounting on Windows relies on WinFsp (Windows File System Proxy), a free, open-source driver that lets OurClone expose Box as a real Windows volume. Install it once before your first mount — without it, the mount won't start.
- 📁 Pick the Right Mount Source — Mount a specific Box folder (say
/Projects) for focused access, or mount the entire account for full File Explorer browsing. A subfolder is usually faster to navigate. - 🖥️ Choose a Sensible Local Mount Point — Point the mount at a dedicated, empty folder like
C:\CloudMounts\Box. Don't aim it at your Desktop or any folder that already has files. - 🔒 Read-Only vs Read-Write — Read-only is the safer pick for browsing; pick read-write to upload, edit, or delete. Read-only mode literally cannot upload — Save dialogs will fail.
- ⏱️ Set a Reasonable Polling Interval — Lower intervals catch changes faster but use more Box API calls. For most workflows 30–60 seconds is a happy middle.
- 💽 Plan Your Cache Size — A bigger cache makes repeat opens snappy but eats local SSD space. Match it to the files you regularly reopen.
How to Mount Box on Windows with OurClone
Once WinFsp is installed, OurClone makes mounting Box on Windows refreshingly straightforward. Step 1 uses Box's standard OAuth sign-in — no API keys, just a browser login — and from there you're a few clicks away from a File Explorer-ready drive.
- 🔗 Connect Box via Browser — Open OurClone and go to
Add Storage. Select Box from the provider list. A browser window will open automatically — log in to your Box account and authorize OurClone to access your storage. Once approved, Box will appear as a connected destination. - 📂 Open the Mount Tab and Click New Mount — Once Box is connected, go to the
Mounttab in OurClone. Click the New Mount button in the top-right corner to open the mount configuration dialog. - ⚙️ Configure the Mount Settings — In the dialog, pick Box as the authorized source. Choose what to mount — a specific cloud folder (e.g.,
/Projects) or the entire account. Then pick an empty local folder as the mount point (something likeC:\CloudMounts\Box). Choose Read-only if you just want to browse, or Read-write if you need to upload and edit. Optionally tweak the polling interval and max cache size. Click Mount to finish. - 🗂️ Use Your Box Mount Like a Local Drive — Open the mount point in File Explorer (it appears under "This PC" as a mounted volume). Windows now treats it as a real drive — browse, open, create folders, drag in files, and delete just like any local folder. Create a new
backupfolder, drop in a few files, and OurClone streams the changes to Box in the background. - ✅ Confirm the Sync on Box — Switch back to OurClone and open your Box storage from the file browser — your new
backupfolder and uploaded files should already be listed. For extra peace of mind, log in to the Box web app and confirm the files appeared there too.
The combination of Box's OAuth sign-in, WinFsp, and OurClone's mount engine gives you a Box that genuinely feels like a local drive on Windows — no manual uploads, no full-disk mirror, just files where you expect them.
Getting the Most Out of Your Box Mount
A live mount is convenient, but it behaves slightly differently from a synced folder. Keep these in mind once your Box mount is up and running.
- 🔁 Edits Sync Both Ways — Anything you add, rename, or delete in the mounted drive propagates to Box. Changes made on other devices appear after the next poll cycle.
- 🛑 Read-Only Means Read-Only — If you mounted read-only, uploads and Save dialogs will fail. Remount as read-write to enable uploads.
- 💾 Cache Lives on Your PC — Recently opened files are cached locally for speed. If your PC is low on disk space, reduce the max cache size.
- ⏱️ Polling Interval Affects Freshness — A short polling interval picks up remote changes faster but increases API calls. For Box, a 30–60 second interval is a good balance.
- 🔌 Unmount Cleanly Before Shutdown — Before shutting down or signing out, click Unmount in the Mount tab to release the volume cleanly.
When Your Mount Stops Working
Most mount failures trace back to one of a few causes: WinFsp isn't installed (or needs a reboot after install), an expired or revoked OAuth token (Box may require re-authorization after a password change), a network drop, or a mount point that's no longer empty. If your Box mount refuses to start, first confirm WinFsp is installed, then unmount, re-authorize Box under Add Storage, and remount.
Verify the Sync Anytime
Any time you're unsure whether something made it up to the cloud, open your Box storage view inside OurClone's file browser, or log straight into the Box web app. Whatever File Explorer shows in your mount point should match.
