You usually do not move the files at all. A Windows file manager is a different way to browse folders that already exist on your drives. Install the new manager, test it against your normal folders, then change only the defaults or launch shortcuts you actually want to change.
Files, Windows file associations, desktop shortcuts, and a manager’s private settings are separate layers. Changing one layer does not automatically migrate the others. A complete switch therefore means checking each layer deliberately and keeping File Explorer available until the new setup has proved reliable.

What changes—and what stays where
File Explorer is a shell application, not a container in which your documents live. Your documents normally remain in locations such as your user profile, another internal drive, a network share, or removable storage. A second manager can open those same paths without importing or duplicating the contents.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minute| Item | What happens when you install another manager | What you must decide |
|---|---|---|
| Documents, photos, downloads and other files | They remain in their existing folders. Installation alone does not copy or relocate them. | Whether to keep the current folder structure and make a separate backup before testing. |
| File and link associations | Windows continues using the registered application until you change an association. | Which extensions or link types should open in the new application. |
| Existing shortcuts | A shortcut keeps its original target. It does not become a shortcut to a different file manager. | Whether to preserve it, create an app shortcut, or pin the manager. |
| Application preferences | The new manager starts with its own configuration. Settings from File Explorer are not a single transferable profile. | Which views, tabs, keyboard mappings, bookmarks and other preferences to configure manually. |
| Explorer launch behavior | Windows shell locations and programs that explicitly call Explorer may continue to open Explorer. | Whether the new manager offers an optional folder-launch or Win+E interception feature. |
This distinction prevents the most common migration mistake: treating “make this the default app for a file type” as “replace every part of Explorer.” Those are different operations with different compatibility risks.

Prepare a safe test environment
Do not change system-wide behavior on the first launch. Start with an ordinary user account and a small set of familiar folders. A separate backup is sensible before enabling any feature that intercepts Explorer or changes registry values; the available Microsoft and vendor guidance does not prescribe one particular consumer backup product or method.
- Confirm that you can still open File Explorer from Start search, the taskbar, or another known route.
- Write down the folders you use every day, including local, network and removable locations.
- Note any specialist tasks: copying large groups of files, extracting archives, previewing media, connecting to a server, or working with cloud-synchronised folders.
- Record your current default applications for file types you care about, such as text, image, archive and document extensions.
- Keep the installer and the new manager’s current help page available in case you need to disable an experimental integration.
If several people use the PC, test under each relevant Windows account. Per-user defaults are controlled by the user; Microsoft’s guidance states, “Only the user can do that.” An administrator deploying a machine is not the same as transferring each person’s private preferences.
Install and test the new file manager first
- Install the manager using its current installer and accept only the integration options you understand.
- Open the application without changing Windows defaults.
- Browse your normal locations:
Documents,Downloads, a folder on another drive, and any network or removable location you depend on. - Perform representative operations: create a folder, rename a test file, copy and move a small group of files, search, open a file in its usual editor, and remove a disposable test item.
- Check the behavior that matters to you, such as dual panes, tabs, previews, archive handling, permissions, long paths, hidden files and keyboard shortcuts.
- Leave File Explorer installed and usable while you evaluate the result.
Testing the same folders rather than a copied sample reveals problems that an empty installation cannot: missing network credentials, unsupported preview handlers, unusual permissions, slow removable media or an extension the new application does not understand.

Use Windows’ supported Default apps controls when your goal is simply to choose which application opens particular file types or link types.
- Open Settings.
- Select Apps, then Default apps.
- Search for a file extension or link type, such as
.txt, or select the application and review the types it supports. - Select the current application shown for that type.
- Choose the new manager, if Windows lists it as a compatible handler, and confirm the change.
- Open a test file of that type and verify the result.
You can work from either direction: search for an extension or link type, or select an app and manage the associations it supports. Make changes one type at a time instead of assigning every available type blindly. A file manager may be useful for browsing a folder but may not be the right handler for documents, images or other content that needs a dedicated editor.
Windows labels can vary slightly by release. If a type is not listed for the application, that does not prove the manager can replace Explorer; it may simply lack a registered handler for that extension. File associations also do not control every context-menu command or every shell location.

Keep, repair or create shortcuts separately
A shortcut stores a target path, command, or application identifier. Changing a default association does not rewrite that target. A shortcut to C:UsersNameDocumentsBudget.xlsx still points to that file, while a shortcut to explorer.exe still launches Explorer.

Preserve file and folder shortcuts
Open several important shortcuts after installation. If the target opens in the expected program, no migration is needed. If a shortcut points to a file manager executable or to explorer.exe, decide whether that specific shortcut should remain an Explorer shortcut.
Create an application shortcut
Use Windows’ normal Start-menu or desktop controls to create a shortcut to the new manager. The shortcut should point to the manager itself, not to a folder you happen to browse most often. This gives you a reliable launch path even if you later turn off Explorer interception.
Pin the manager
Pinning is another independent choice. Windows shell guidance describes Start-menu shortcuts and treats taskbar pinning as a user choice. Pin the new application only after testing it, and keep a visible File Explorer route until the evaluation is complete.
Decide whether to intercept folders or Win+E
Some file managers offer an optional “default file manager” mode or a setting that redirects Win+E. These features affect launch behavior, not file storage.
| Approach | Scope | Compatibility question | Risk and reversibility |
|---|---|---|---|
| Default-app association | Selected file extensions or link types in Settings. | Does the chosen application support the exact type? | Ordinary user-controlled change; switch the type back in Default apps. |
| Folder-launch interception | Some attempts to open folders or shell locations. | Do special locations and programs that explicitly invoke Explorer still behave correctly? | Depends on the manager; may be experimental or registry-backed. |
| Win+E redirection | The keyboard shortcut, sometimes only while the manager is running or by starting it. | What happens when the manager is closed, unavailable or running under another account? | Separate from full Explorer replacement; disable it if behavior is confusing. |
| No interception | Only the manager’s own shortcut, pinned icon or manual launches. | Can you live with Explorer opening from shell surfaces? | Lowest setup risk and easiest rollback. |
Example: OneCommander version 3
OneCommander’s version 3 help describes registering it as the default file manager as experimental and warns that registry changes may be needed if something goes wrong. The same manual documents Win+E redirection as a separate option and says File Explorer remains available through other launch paths. Those instructions describe that version’s design, not a guarantee for every later release.

If you choose such an option, read the current release documentation first, note the exact setting name, and test a rollback before relying on it. Do not promise that it will replace Windows’ Open or Save dialogs, special shell pages, or applications that directly launch Explorer. A program can continue calling Explorer even when a keyboard shortcut has been redirected.
Configure the new manager’s own settings
File Explorer does not expose one universal “export all my Explorer settings” package that another application can consume. A new manager normally has its own preferences, database, profile folder and plug-in model. Treat those as application-specific.
Recreate the settings that matter
- Choose a default view, column set, sort order and grouping for the folders you use most.
- Recreate bookmarks, favorites, saved locations or workspace tabs.
- Set visibility for hidden items and file-name extensions deliberately.
- Review confirmation prompts for deletion, overwriting and bulk operations.
- Configure preview, archive, terminal and editor integrations only after checking what each integration launches.
- Learn the manager’s reset or safe-mode procedure before importing third-party themes or extensions.
Copying an undocumented profile directory from one program to another is not a supported migration method. It may overwrite a newer configuration, contain machine-specific paths, or fail because the program stores settings in the registry or a protected location. If the vendor documents an export and import function for its own versions, follow that documentation and keep the original profile until the import is verified.
Do not confuse deployment XML with a personal migration
Microsoft documents exporting default-app associations to XML on removable media and importing them into Windows images. That workflow is intended for IT deployment and must remain aligned with the Windows versions involved. It can be useful when preparing multiple managed installations, but it is not evidence of a general consumer method for moving every third-party file-manager setting from one PC to another.
A USB flash drive can carry a backup or an exported association file if you already have a reason to use one. The documentation does not establish a required capacity, speed, brand or consumer migration package, so do not treat removable media as a magic settings-transfer tool.

- Removable and network storage: Disconnect and reconnect a test device or share, then check whether the manager refreshes and reports errors clearly.
Rollback plan
- Turn off the new manager’s default-file-manager, folder-interception or Win+E option using its current settings page.
- If the vendor warns that registry changes may be involved, follow its documented rollback procedure rather than deleting keys at random.
- Return changed extensions or link types through Settings > Apps > Default apps.
- Unpin the manager or remove its shortcut only if you no longer need it; this does not affect your files.
- Open File Explorer from Start search or another known route and test the folders and shortcuts that matter.
- Restart Windows if the vendor’s instructions require it, then verify both Explorer and the new manager before uninstalling anything.
If you cannot find the new application in Default apps, first check whether it registered itself as a handler. If it did not, use its own shortcut rather than forcing an association that Windows does not offer.
Troubleshooting common migration problems
A folder still opens in File Explorer
Check whether you changed only a file extension. That setting does not intercept every folder launch. Look for a separate folder or default-manager option in the application, and confirm that the current release supports it. Programs that explicitly call Explorer may continue to do so.
Win+E behaves inconsistently
Read the feature’s scope carefully. Some implementations redirect the key only while the manager is running; others start the manager. Test with the application closed, after sign-in and under another user account. Disable the option if you need predictable Windows behavior.
A shortcut opens the old application
Inspect the shortcut target. A shortcut can contain an explicit executable path or command, so changing a file association may not affect it. Edit or recreate only that shortcut, and preserve its arguments if the target program needs them.
Double-clicking a file does nothing useful
Return to Default apps, select the exact extension, and confirm that the selected application supports it. The manager may be suitable for browsing but not for opening that file format. Choose a dedicated application when Windows offers one.

Context-menu integration is distinct from file-type association. The new manager may not provide an equivalent shell extension, and Windows’ packaged-app mechanism uses its own command registration. Keep Explorer for that task or use the manager’s documented command if one exists.

The new manager cannot reach a network or protected folder
Verify the path and credentials in File Explorer first. If Explorer also fails, the issue is probably permissions, connectivity or authentication rather than migration. If only the new manager fails, check its network, elevation and access settings before changing Windows defaults.
Migration plans for different users
Cautious everyday user
Install the manager, test familiar folders, create a pinned shortcut and leave all Windows defaults unchanged. This gives you the new workflow without risking shell behavior. Change one file association later if a specific extension benefits from it.
Power user who wants a keyboard-driven workflow
Test tabs, panes, search and custom shortcuts first. Then trial Win+E redirection for a day while keeping a Start-menu path to Explorer. Record the exact setting you changed so it can be reversed after an update.
Shared or managed computer
Make changes per user unless you are administering an image. Keep personal preferences out of a deployment XML workflow, and validate the Windows version before exporting or importing default associations. Document which account owns each change.
When the migration is complete
Consider the switch complete only when the new manager handles your real folders and tasks, your required extensions open in the intended applications, important shortcuts have been checked, and you can still reach Explorer for compatibility work. At that point you can remove redundant pins or shortcuts, but there is no technical need to relocate the underlying files merely because the browsing application changed.
