Foldr Technical Information Sheet
What is Foldr?
Foldr is a multi-platform remote file access and sharing solution which can provide access
to all regular network shares and personal home folders. Users can download files for
use offline, send to third party apps for manipulation / editing, annotate and mark up
documents providing graphical, textual or audio feedback and upload files, photos and
videos back to their network.
Foldr works with iOS, Android, HTML5 web browsers and any WebDAV client.
Utilising your existing network accounts and storage, Foldr is a true plug-and-play
solution. All communication with the Foldr server takes place over HTTPS/SSL so files
remain encrypted in transit.
Foldr provides your network and servers with a whole new lease of life - simply, safely
and securely.

from thousands of apps directly to your network storage.
• Mark up and annotate documents. Great for working
collaboratively or marking work.*

your files within other apps.*
• Use your existing MDM provider to configure app mode,
server and security settings.*
• Open and edit files and save them directly back to your
network without leaving the Foldr app.**
*iOS only feature
**Android only feature
File Sharing
Foldr allows users to create short URLs to resources on your
network without duplication using 'fLinks'. fLinks may be
either private or public, with the former requiring network
authentication to access shared material. fLinks are the
perfect solution for sharing files or folders that are sensitive
in nature or too big to send as an email attachment. fLinks are
configurable per-share.
Media Streaming
Using HTTP Live Streaming, Foldr turns your existing file
servers into a media streaming solution. Available in both
the iOS app and web app, media can be streamed and then
broadcast via AppleTV or Chromecast with no additional
software required - great for front-of-class presentations and
digital signage. Using the built-in player, videos can also be
shared and embedded in websites and blogs without leaving
the network.
Why is Foldr only available as a virtual appliance?
By delivering Foldr as a virtual appliance (a ready to run virtual machine), we’ve been able to make it hardware-independent
and remove the requirement for any external software dependencies (other than a compatible hypervisor).
What are the network requirements?
Foldr uses LDAP for authentication and your existing file servers for storage. The following network environments are
supported by Foldr:• Microsoft Active Directory 2003/2008/2012 with Active Directory-based Windows/SAMBA file servers.
• Apple OpenDirectory with OpenDirectory-based OS X/SAMBA file servers.
• OpenLDAP with SAMBA file servers.
• Windows/SAMBA file servers in share-only mode.
What are the system requirements?
1vCPU, 2GB RAM and up to 40GB HDD. These specs can be increased to accommodate more concurrent users.
What hypervisors are supported?
VMware vSphere, ESXi, Workstation & Fusion, Microsoft Hyper-V 2008 & 2012, Citrix Xen, Parallels and VirtualBox.
Can I use one of my existing servers to also run the Foldr appliance?
Yes, using a host-based virtualisation product you can run Foldr on an existing server on your network.
Can I choose which shares are presented to users?
By default Foldr will attempt to search your directory for the path to the users home folder. Other shares can be added
quickly and since Foldr respects your existing permissions your users will only see what they are supposed to see.
We have user-specific shares or mount our home directories using login scripts, will these work with Foldr?
Yes, specify a share path containing %USERNAME% and Foldr will automatically convert this into the user’s account name
when they authenticate.
Are DFS shares supported?
Yes, Foldr fully supports DFS shares.
What changes need to be made to existing permission structures?
None, Foldr respects your network permissions with no additional configuration.
How does Foldr authenticate users?
Using their existing Active Directory/OpenDirectory/OpenLDAP account credentials. Foldr does not require any new
accounts to be created or any kind of directory synchronisation.
Does the Foldr server appliance require binding to a domain?
No, the Foldr appliance only needs to be able to reach the domain controllers and file servers on the network. No binding is
Are Active Directory subdomains supported for authentication?
Yes, as long as the Foldr appliance is able to correctly resolve the subdomains with DNS.
Can we share entire folders with others in our organisation and/or external users with Foldr?
Yes, fLinks can be created for folders as well as files. The folder is then downloaded as a dynamically created zip file so
changing the contents does not require that the fLink be recreated. The recipient of the link can also browse the shared
folder to select individual items to download.
Does Foldr require any administrative network credentials to operate?
No, it uses the credentials of the logged in user to access the network. Should you wish to enable fLinks on a share you may
need to provide the appliance with credentials able to access the share but these need only have read access and are not
visible to users.
Why use Foldr when you could setup your own WebDAV server?
Foldr can present all of your existing shares from a single WebDAV root, connect to one address and see all of your available
How are software updates delivered?
The Foldr appliance has a built in mechanism for receiving updates over the internet. Updates can be scheduled or run
manually. App updates are delivered from the Apple App Store and Google Play.
Are network files ever stored or cached on the Foldr appliance?
No, the Foldr appliance is simply a gateway between your files and your connected users. Foldr does cache the preview
thumbnails that it generates of certain file types but these are not accessible to users and are regularly cleared by the
appliance's housekeeping routines.
What network ports does Foldr require to be open?
All user access takes place over HTTPS (TCP port 443). Other ports are used for system configuration, appliance
configuration and proxy PAC hosting; TCP 35374, 5480 and 8080 respectively but we would not recommend that these be
opened up beyond your LAN.
Can I install a trusted or self-signed certificate for use with Foldr?
Foldr ships with a default certificate but this can be replaced with either a self-signed certificate or one purchased from a
recognised certificate provider.
Can I store network files on my iPad/iPhone/iPod/Android device for offline use?
When you 'Favourite' a file in the app it is downloaded to your device - perfect for a presentation or meeting where internet
access may not be available.
Can I prevent my data falling into the wrong hands if my device is lost / stolen?
Files are automatically encrypted on the device if running iOS 8 or Android 5.0 upwards. Previous versions of these operating
systems will encrypt your data providing a pin/passcode has been set on the device. Additionally the Foldr app itself can be
pin/passcode protected for those who require an extra layer of security. iOS users can also unlock the app with a fingerprint.
Can Foldr solve problems with iOS, proxy servers and accessing internal resources?
Generally if you use a proxy server to access the internet you would set your internal addresses as proxy exceptions.
Unfortunately there is no way of doing this from within the Settings app on iOS but it can be done by using a PAC file. Foldr
comes with a pre-configured PAC file template which can be used to provide proxy settings for your iOS (and other) devices.
