Files of any size
Video, CAD models and archives — without the 50 MB limit or the 4 GB ceiling.
A real drive letter in File Explorer: files open straight from SharePoint, without syncing the whole library. For people — and for apps that need a file path: ERP, Access, CAD, backup.
Free 14-day trial · no credit card
One file, no admin rights.
Your usual work sign-in; OneMount finds sites and libraries on its own.
Drives are already in File Explorer; the trial starts automatically.
No Entra ID registration or admin consent — OneMount works in any Microsoft 365 organization.
Admins deploy the app and drive configuration centrally. Users simply get OneMount from the Microsoft Store, sign in and work.
For those tired of OneDrive sync issues who want to deploy storage the same way, automatically, on every new PC.
For those who don't want to dig through SharePoint sites or fight OneDrive sync. All files live in a familiar network drive with its own letter.
No addresses to copy. OneMount finds everything your Microsoft 365 account can access: SharePoint sites, Teams channel files, your OneDrive and folders shared with you.
Pick a library or folder — and a moment later it's a drive in File Explorer.
A Word or Excel file opened from a OneMount drive is a live document in SharePoint, not a local copy, so everything your team relies on in Microsoft 365 keeps working:
Supports Word, Excel and PowerPoint files from OneMount drives. Requires a Microsoft 365 sign-in in your default browser.
Right-click any file or folder on the drive — no need to open SharePoint in the browser:
ERP, AutoCAD, Photoshop and other apps work with SharePoint as with a local drive — each drive is served by its own SMB share.
Video, CAD models and archives — without the 50 MB limit or the 4 GB ceiling.
The path counts from the drive letter, so deep folders stay visible. OneMount warns you about paths that are too long.
Give a SharePoint folder, such as “Projects”, its own drive letter: shorter paths and a tidier view.
If a save didn't reach the cloud, OneMount retries, and sets anything not uploaded aside in a safe place — never deleting it.
Copying to and from the drive is as fast as through the browser.
We test OneMount live: opening, saving, temporary and backup files, co-authoring — the way the apps themselves do it.
Comparing OneMount with OneDrive sync (including “Add shortcut to OneDrive”), third-party drive-mapping apps and the Windows built-in WebDAV network drive.
OneMount | OneDrive sync | Other apps | Windows WebDAV | |
|---|---|---|---|---|
Drive letter for apps | Yes | Only via subst | Yes | Yes |
Tenant setup | Not required | Not required | Usually app registration and admin consent | Trusted sites and IE mode on every PC |
Storage in other organizations where you're a guest | Yes — with the same account | Only B2B Sync, if admins allow it | Usually your own tenant only | Separate browser sign-in for each |
Own and guest storage at the same time | Yes — each with its own drive letter | Limited, shortcuts to external storage don't work | No | No — sessions conflict |
Stable connection | Sign-in renews itself | Yes | Yes | Drops after a few hours |
Disk space | Almost zero — files on demand | A placeholder for every item | Local cache | None |
Libraries with millions of files | Yes | Microsoft recommends up to 300,000 items | Varies | Yes |
Real-time co-authoring | Yes, with AutoSave | Yes | Often not: file is locked | Unreliable |
Conflict copies | None — one live document | Duplicates with computer name | Often, when several people edit | None |
Files over 4 GB | Yes (Windows 11 24H2+) | Yes | Yes | 50 MB by default, 4 GB max |
Third-party apps vary — the column shows the typical approach. OneMount works alongside OneDrive sync, not instead of it.
A new PC or a freshly reset virtual machine — and within a minute all drives are in File Explorer. OneMount syncs nothing up front, so it doesn't eat memory, CPU or disk even on weak machines.
Licenses, devices and drive settings for every employee — from a small team to the whole company.
OneMount · AccountCNTS-7F4K-92QX-MGBNCopyOneDrive syncs every change — accidental or malicious. OneMount adds dated snapshots of any folder: from the PC to SharePoint or OneDrive, from SharePoint libraries to a disk or NAS. Restoring a whole folder takes one step.

Briefly about installation, security, daily work with files and payment.
No. OneMount needs no app registration in Microsoft Entra ID (Azure AD) and no admin consent — you sign in with your regular Microsoft 365 account. Windows admin rights aren't needed to install either — the app installs per user from the Microsoft Store.
