FolderMount for Windows
Map Folders to Virtual Drive Letters
Assign fast, clean drive letters (like P:, M:, Z:) to any directory on your PC. Eliminate nested path limits, organize project workspaces, and mount folders with zero UAC elevation and automatic re-mount on login — powered by native Windows SUBST.

SUBST P: "D:\Projects\WebApps\CorePlatform"
Built for Real Productivity. Designed for Real Workflows.
Whether you are building complex software, editing multi-gigabyte 4K timelines, or organizing scattered projects across multiple drives, FolderMount turns complex directories into immediate, clean drive letters.
Developers & Engineering Teams
Deeply nested dependencies like node_modules, Python virtualenvs, and Git submodules easily trigger Windows 260-char path limits. Mounting your project root as P:\ instantly slashes path depths by 80% and eliminates build crashes.
- Standardizes absolute paths (e.g.
P:\config) across team members' computers. - Eliminates
PathTooLongExceptionin VS Code, npm, and compiler toolchains. - Lightning-fast terminal jumps with
cd P:without navigating deep folder trees.
Video Editors & 3D Artists
Creative suites like Adobe Premiere Pro, DaVinci Resolve, and Blender rely heavily on linked media files. When assets are scattered across secondary hard drives or external storage, project links break when drive paths change.
- Map high-speed SSD cache or HDD archives directly to
V:\FootageorA:\Assets. - Keeps timeline references intact across workstations without "Offline Media" errors.
- Direct 1-click access in native file dialogs and media bins.
Gamers & Modding Enthusiasts
Managing massive mod packs, texture overhauls, and custom assets for games often strains system drives or requires digging into hidden AppData directories.
- Mount custom mod staging libraries and texture caches from separate SSD drives.
- Avoid modifying or duplicating game installation roots on your primary drive.
- Easily toggle or isolate different mod loadouts with clean drive assignments.
Business & Power Users
Buried corporate folders, synced OneDrive / SharePoint directories, and nested client files waste valuable time every day when opening or saving documents in Office and browser windows.
- Turn deeply nested client paths into immediate top-level drives like
W:\Clients. - Runs strictly in user space with zero administrator or UAC elevation required.
- Perfect for locked-down corporate laptops, university lab PCs, and remote desktops.
The Dedicated Folder Mounting Solution for PC
Power users have long understood the immense value of folder mounting to organize scattered files, redirect heavy directories, and bypass rigid storage limitations. FolderMount for Windows brings this essential folder mounting capability to Windows 10 & 11 as a polished, native desktop application.
Instead of needing device root or complex terminal scripts, FolderMount for Windows harnesses the standard Microsoft SUBST architecture. It turns any directory into an instant, native virtual drive letter that is immediately recognized by Windows Explorer, command prompts, and every desktop application—persisting seamlessly across reboots.
Bypass the Infamous Windows 260-Character Limit
Ever hit PathTooLongException or Filename too long while working with deeply nested node_modules, Python venvs, or Unity assets? FolderMount solves it permanently.
Everything You Need. Zero Bloat.
Built as a native Windows desktop app using .NET Framework 4.8. No Electron, no kernel hooks, and no administrator barriers.
Zero Admin Rights & No UAC Prompts
FolderMount operates strictly inside user space. It installs to %LOCALAPPDATA% and writes configuration exclusively to HKCU. Perfect for corporate workstations, restricted work laptops, and school lab environments where you cannot get administrator rights.
Persistent Across Reboots
Standard Windows SUBST drives vanish the moment you restart. FolderMount silently registers in HKCU\Run with /startup to re-mount all your drives instantly on login.
FolderMount.exe /startup (silent mount)
Export / Import XML Profiles
Keep your team in sync. All drive configurations are saved in clean, human-readable XML at %APPDATA%\FolderMount\mappings.xml. Export and commit to Git or share across machines.
<Mapping letter="P" path="D:\Code" />
Unobtrusive System Tray
Lives quietly in your Windows notification area. Closing the window minimizes it directly to the tray so your workflow remains clean and distraction-free.
Featherweight Native WPF
No heavy web frameworks or Chromium bundles eating 400 MB of RAM. FolderMount consumes less than 15 MB of memory, launches in under 200 milliseconds, and has 0% idle CPU usage.
How FolderMount Compares
See why developers and power users choose FolderMount over raw commands and fragile workarounds.

Frequently Asked Questions
Everything you need to know about FolderMount, virtual drives, and Windows SUBST.
Does FolderMount require administrator or UAC privileges?
SUBST command, which has been standard in Windows since Windows XP and operates entirely in user space. The app installs from the Microsoft Store to your user profile and writes startup entries only to HKCU.
How do mapped drives persist across Windows reboots?
SUBST mappings are temporary and vanish when the user logs off or restarts. When you enable "Run at Windows startup" in FolderMount Settings, the app registers a silent startup entry in HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Run with the /startup parameter. When you log in, FolderMount reads your XML configuration and re-mounts all your active drives instantly in the background without opening any windows.
How does this solve the Windows 260-character path limit (MAX_PATH)?
MAX_PATH). Modern development stacks like Node.js (node_modules), Python packages, and Git repositories frequently generate paths exceeding 280+ characters, causing build failures and file locking. By assigning a drive letter like P:\ directly to your project root, you eliminate 100+ characters of prefix path, ensuring all build tools and Explorer operations succeed seamlessly.
Does FolderMount install kernel drivers or virtual filesystem services?
Where are my drive mappings stored? Can I back them up?
%APPDATA%\FolderMount\mappings.xml. You can open, back up, export, or import this file with a single click in FolderMount Settings. This makes it effortless to replicate your drive layout across multiple developer workstations.
What happens if a drive letter is already in use by a physical disk?
C:, D:, optical drives, or existing network mappings). The drive letter dropdown only lets you pick truly available letters (A-Z), preventing collisions.
Is FolderMount for Windows related to the legacy Android FolderMount app?
SUBST architecture to assign virtual drive letters to local PC directories in user space with zero administrator privileges.
