Deploying Foldr for Windows
The installation process will require Windows to be restarted before
The Windows drive mapping client can be deployed to multiple computers using common software deployment tools. These include Group Policy, SCCM, scripts, or open-source deployment tools. It is recommended that the MSI remains accessible to the client, whether local or over network connection if deployed centrally.
IMPORTANT – If deploying the app using a central deployment tool such as those listed above, it is important that you DISABLE the ability for users to install updates using the MSIEXEC option ‘UPDATES_ENABLED=0’ or setting the appropriate registry key (see below).
The administrator can optionally pass additional options to the installer to configure the application as required.
Restart Requirement
The installation process requires the Windows PC to be restarted after installation before the app can be used. This applies to both new installations and upgrades.
During the installation a file is placed into %commonprogramfiles% to detect if this restart has occurred. More information is available here.
Antivirus Recommendations
Antivirus software can interfere with the running of the application and severely impact the performance/user experience when using the Foldr drive.
It is recommended that antivirus software is modified so that both the mounted Foldr drive (Z:\ for example) and the local cache location is excluded for both real-time and on-demand scanning.
If antivirus software is not configured correctly, it may scan the drive and crawl through the shares and directories available resulting in many files being downloaded to the local cache, which is undesirable.
The application cache is stored at within the users local AppData directory which by default is available at:
%localappdata%\foldr\cache
or
C:\Users\<username>\Appdata\Local\Foldr\cache
Note the cache directory is a marked as a protected operating system folder and is hidden in Explorer by default. The cache location may be customised if required.
The Process Filter feature on the Foldr server (Foldr Settings >> Devices & Clients >> Windows) may also be used to blacklist antivirus, or other software applications such as inventory collection software from interacting with the drive.
Registry Settings
By using any of the following msiexec installer options, registry keys are created automatically for each under:
HKEY_LOCAL_MACHINE\SOFTWARE\Foldr\Default
These keys apply to all users of the system and as such an administrator can configure the Foldr app by pushing these registry values to workstations, instead of using the msiexec options. This is typically done via Group Policy Preferences or via a script.
Example Installation Command
msiexec /i FoldrSetup.msi /quiet /log install.log FOLDR_SERVER=https://demo.foldr.io REQUIRES_ANTIVIRUS=1 DETECT_RENAME_THREAT=1 DETECT_EXTENSIONS_THREAT=1 FOLDR_DRIVE="R:" SHARES="1,3"
An elevated command prompt should be used (Run as Administrator) when using msiexec.

Preventing / Delaying Windows Restart
By default, using MSIEXEC will restart the computer automatically after the installation has completed. This may not be desirable in a mass deployment scenario or if the app is deployed during normal working hours and the reboot may interrupt users. The administrator can be prevent / delayed using the standard MSIEXEC / Windows Installer argument:
REBOOT=REALLYSUPPRESS
For example:
msiexec /i FoldrSetup.msi /quiet /log install.log FOLDR_SERVER=https://demo.foldr.io REBOOT=REALLYSUPPRESS
Option Details
FOLDR_SERVER=<SERVER ADDRESS>

NO_CACHE_MSI=1|0
Use to inform the installer whether to preserve a cached copy of the FoldrSetup.msi installer. This means that when Windows needs the installer (after a major Windows update for example) there will be a copy available and Windows will not prompt the user for its location.
If the argument is not supplied, or is set to ‘0’, then the installer caches the MSI in a directory named ‘%COMMONPROGRAMFILES%/Foldr’
If the argument is set to ‘1’, then installer does not cache the MSI.
This argument to the installer is not stored in the Windows Registry
EXCESSIVE_DOWNLOAD_ALERTS=1|0
This setting configures whether or not Foldr notifies a user when it detects excessive download activity for a particular process (for example, an Antivirus product scanning files on the Foldr drive).
If the argument is set to 1, then Foldr will issue alerts. The user will be unable to configure the setting.
If the argument is set to 0, then Foldr will not issue alerts. The user will be unable to configure the setting.
When unset, the user will be able to configure the setting, The default value is 1.

If the argument is set to 0, AdminUpdates is disabled. The user will be unable to configure the setting.
When unset, the user will be able to configure the setting in the App Settings UI (Advanced tab). They will need to satisfy a UAC prompt in order to do so.
Registry Setting
Name = AdminUpdates
Type = REG_SZ (String)
Value = 1|0
Office Assist (Open Office 365 documents natively via double-click)
OFFICE_ASSIST=1|0
This setting configures whether or not Office documents are associated with the Foldr app (while the Foldr app is running). Double-clicking Word, Excel or PowerPoint files will open documents direclty via the SharePoint/Office 365 URL and use the Office apps direct/built-in saving mechanism to save back to OneDrive, SharePoint and Teams. Saving files bypass the Foldr upload queue, results in no temporary files being created (~$ prefix Office owner files), enables the autosave feature in the Office apps and allows for native collaborative editing.
Note – The Office Assist feature can only open documents ‘directly’ when they are double-clicked in the Foldr drive in Windows Explorer.
Using File > Open as a route to open documents in any Office application will use the standard (local) file opening mechanism and Office 365 native auto save, collaborative editing etc will not be available.
Users will still be able to open Office documents hosted outside of Foldr (local documents or on SMB mapped drives) with Office Assist enabled.
When Office AssistThe local file association is modified on the Windows client when the Foldr is running for .docx, .xlsx and .pptx files as shown below:
When the app is quit, the file association will automatically revert to default, as shown below.
If the argument is set to 1, then OfficeAssist is enabled. The user will be unable to configure the setting in the app.
If the argument is set to 0, OfficeAssist is disabled. The user will be unable to configure the setting in the app.
When unset, the user will be able to configure the setting, The user is prompted, at startup, for its initial value.
If the user is allowed to enable Office Assist manually in the app, this can be done in the app Settings > Advanced tab as shown below using the button labelled Use Foldr to open Office 365 documents.
The functionality to edit ‘online’ can be used without Office Assist being enabled by using the context menu in Explorer > Foldr > Edit in Microsoft Office. As with OfficeAssist, the context menu will open the file directly using its online URL, autosave is enabled automatically and native collaborative editing is supported.
Registry Setting
Name = OfficeAssist
Type = REG_SZ (String)
Value = 1|0
NOTE – It is recommended that users open Office files hosted in Office 365 locations by double-clicking the files to open in their File browser (Windows Explorer). This ensures the online version is opened rather than using File > Open inside the Office app – see below.
When Office Assist is enabled, the app will block the File > Open route of opening Office files hosted in Office 365 locations from the Foldr drive. This is to prevent a local / offline version of the file being opened. If a user tries to use File > Open with Office Assist open, they will see the following error:
A Windows notification will appear (bottom right) and if the user clicks this, the online document will be opened in the local Office app.
After clicking the notifcation above. the user can continue working on the file natively using the online version – autosave, collaborative editing and any other native Office 365 features available in the Office app will function as usual.
OFFICE_ASSIST_ALLOW_OPEN
When Office Assist is enabled, the feature, by design (as of app release 1.5.23) will prevent users from directly opening Office documents from inside an Office app hosted in any Office 365 location using FILE > OPEN > Z: (i.e. the Foldr Drive letter) – Excel error shown below if a user tries to open an Excel file in OneDrive, with Office Asssist enabled and the file is hosted in OneDrive, SharePoint or Teams:
Office Assist users should instead browse through Explorer, via the Foldr drive and double-click files to open. This allows the file to be opened directly via it’s online Office 365 URI and the Office app works natively as if Foldr is not involved in the workflow.
The Foldr app blocks File > Open as a route to open Office 365 files as it is unable to open the ‘online’ document version at Office365 using this route. If the user attempts this they will receive an error that the Office app was unable to open the file (as the app is blocking the action) and a Windows notification will appear to allow the user to open the cloud version by clicking upon the noticication.
-
- 1 – OfficeAssistAllowOpen is enabled. The user will be unable to configure the setting.
- 0 – OfficeAssistAllowOpen is disabled. The user will be unable to configure the setting.
- When unset, the user will be able to configure the setting
Registry Setting
Name = OfficeAssistAllowOpen
Type = REG_SZ (String)
Value = 1|0
PRESERVE_WFR_ON_SIGN_OUT
Working File Recovery (WFR) is a feature that provides an in-app recycle bin for files that have been worked on from the Foldr drive. The app and it will keep a copy of each document/file in the WFR location for every save action.
By default files in the WFR location (%localappdata%\Foldr\cache\restore) will remain if the app is quit (or machine is shutdown). However, if the user signs out of the app, the default behaviour is for files in the WFR store to be deleted. Foldr will automatically manage files in the WFR store in-line with the setting to manage the cache (Clear cached files after x days). Manually clearing the cache will not affect files in the WFR store.
The admin option PRESERVE_WFR_ON_SIGN_OUT allows the administrator to change the app behaviour so files in the WFR store are not deleted if the user signs out of the app.
If the argument is set to 1 – Working files in the filesystem cache\restore folder are preserved on sign-out. The user will be unable to configure the setting.
If the argument is set to 0 – Working files in the filesystem cache\restore folder are removed on sign-out. The user will be unable to configure the setting.
When unset, the user will be able to configure the related user-setting in the app settings > Advanced tab > Working File Recovery > Preserve files on sign-out button. Shown below:
Registry Setting
Name = PreserveWFROnSignOut
Type = REG_SZ (String)
Value = 1|0
PROXY
By default Foldr will use the device configured proxy. This option allows the administrator to configure the Foldr app to use an alternative proxy for app communications.
The proxy should be specified using the proxy address appended by the port. For following examples are valid:
10.1.1.1:8080
myproxy.com:8080
http://myproxy:8080
Note: This setting ONLY applies when USER_CAN_CHANGE_PROXY / UserCanChangeProxy is also set to 0
Registry Setting
Name = Proxy
Type = REG_SZ (String)
Value = address:port
USER_CAN_CHANGE_PROXY
This configures whether the user may configure a manual HTTP proxy in the app settings.
-
- 1 – the user may configure a proxy the setting.
- 0 – The user will be unable to configure a proxy, the option is greyed out and the admin configured proxy (set using the Proxy registry key above will be used)
- When unset, the user will be able to configure a proxy
Registry Setting
Name = UserCanChangeProxy
Type = REG_SZ (String)
Value = 1|0
USE_OFFLINE_FILES
Used in conjunction with USE_MY_FILES to determine whether the ‘Offline Files’ directory is shown in the root of the Foldr drive.
Note:
When a value is assigned to this setting, then the user will be unable to override the configured value.
Registry Setting
Name = UseOfflineFiles
Type = REG_SZ (String)
Value = 1|0
CACHE_LOCATION
This configures the location Foldr uses for its local cache of files that have been downloaded from the server or are waiting to be uploaded.
• Empty – Use the default cache location (%localappdata%\Foldr\cache), or the location configured by the user in the app settings.
• Non-Empty: Specifies the location of Foldr’s cache. The final location will be a subdirectory (named ‘foldr.cache’) of the configured value.
Note: The value may include environment variables, such as “%LOCALAPPDATA%\custom-location”.
Registry Setting
Name = CacheLocation
Type = REG_SZ (String)
Value = (Example) “%LOCALAPPDATA%\location”

Upgrading the app
By default, the app can be upgraded by the user (if they have administrative permissions to install software) via the built-in update mechanism in the app. Alternatively updates can be pushed out via an administrator in a centrally deployed install.
If the administrator enabled the ‘AdminUpdates’ option in the app, either at time of install, or later by configuring the required registry key, non-administrative users are able to check for and install app updates using the built-in update option which can be loaded via in the Foldr system tray icon.
Important: The app should not be uninstalled to upgrade between versions.
If the app is uninstalled manually for any reason the computer must be restarted before reinstalling the app. This restart is important to clear up the file system driver.
If upgrades are being controlled via Group Policy it is vital that the administrator does NOT uninstall the application (when removing the previous MSI), before installing the new version. See here for more information.
Uninstalling the app
The application can be uninstalled using either the Control Panel or via a software deployment tool such as Group Policy.
IMPORTANT – It is important to reboot the computer immediately after uninstall to clean up the file system driver. If the app needs to be reinstalled on the computer, failure to restart before this occurs will result in issues with the file system driver loading correctly and the drive will fail to mount.
