Files Pro, Files and Documents Pro include extensive help built in to the application. Just tap the help button at the top of the main window to view this information.
With iTunes File Sharing you can copy documents to and from Files via USB.
File Sharing requirements:
Connection instructions:

Note: due to limitations in iTunes only files (not folders) can be uploaded using File Sharing. It is however possible to download folders, but not to browse within subfolders.
You can view video tutorials walking through connection set up for Mac OS X, Windows XP, Vista and 7.
To get the Files server URL start Files and click the round button in the lower left of the window. This will display information about the server, including the URL you need to connect to Files. If your device is not currently connected via Wi-Fi you can't connect to Files until you join a wireless network.
Your Mac/PC must be connected to the same local network as your iPhone/iPad to connect to Files. The iOS device must be connected via Wi-Fi.
You can check the connection by starting Files and then entering Files' URL in a web browser on your computer. If the browser loads a page showing the Files' web interface then you have a good connection.
If the browser fails to load the page then see the Network section below for some suggestions for resolving problems.
Files has always included Bonjour support.
If your WebDAV client supports Bonjour this means that on Mac OS X, or on Windows (with Safari or iTunes installed), you can use your device's name, rather than the IP address, as the WebDAV URL.
For example, if you phone is called "iPhone" in iTunes you can use the following WebDAV URL to connect to Files:
http://iPhone.local
Notes:
If you have Guest Access enabled then users can connect to your Public folder without requiring authentication. Guests should append "Public" to the Files URL e.g.
http://iPhone.local/Public
Perhaps the easiest way to upload, download and manage your documents is to connect to Files using a web browser. Just enter Files' URL into the browser location field and you'll be connected and ready to go.

On both Mac and Windows we recommend using the free WebDAV client Cyberduck http://cyberduck.ch to connect to Files.
Cyberduck is very simple to use and is often faster and more reliable than the Finder or Windows Explorer.
To connect, simply type the Files' URL into Cyberduck's quick-connect text field.
Cyberduck also supports Bonjour so it will automatically recognise Files, making connection very straightforward with no need to manually enter a URL. Note that Files must be the active application on your device otherwise it won't be listed as a Bonjour device.


Notes:
To connect from Windows XP
To connect from Windows Vista/Windows 7:
Vista/7 users have two options for connecting to Files. You can either map a network drive to the Files server, or create a network location. Both methods are described below.
Option 1: Map a Network Drive
Note: If you have problems authenticating try entering your username/password by clicking on the "different user name" link, before clicking Finish. This will map Files to a network drive with a name such as: "DAVWWWRoot (\192.168.0.4) Y:"
To reconnect in future just open this network drive from Computer.
Note: If you change your username or password you may need to re-create the Network drive to gain access to Files.
Option 2: Create a Network Location
In future, assuming the Files URL has not changed, you can connect to Files simply by opening Computer and double-clicking the network location you just created. You may need to select "Refresh" from the window's context-menu to ensure that Windows has an up-to-date view of your files and folders.
Note: If you change your username or password you may need to re-create the Network location to gain access to Files.
Vista 64 bit: Users of Vista 64 bit may find that connection to Files from Windows Explorer fails. There are two known solutions to this problem:
Please contact support if you have any problems.
Only the fusedav WebDAV driver is fully compatible with Files on linux. To connect using fusedav:
If you are finding that copy operations to or from Files are timing out then enable the Prevent Sleep option in Files' setttings.
Another alternative is to connect to Files using a compatible 3rd party WebDAV client.
On both Windows and Mac we recommend using the free client Cyberduck to connect to Files.
Cyberduck has excellent support for WebDAV and also supports Bonjour so it will automatically recognise Files making connection very straightforward with no need to manually enter a URL.

If you cannot establish a connection to Files from a web browser then you may have a problem with your local network setup. In the first instance check that:
Some users have found that the following solutions have solved network connection problems:
One user reported that disabling the "Wireless isolation" setting on his Netgear router enabled connection to his iPhone.
Some Linsys routers (e.g. WAG160N) have a setting which blocks anonymous internet requests, this is found on the security page of the router's settings. Turning this setting off may solve connection problems.
Rebooting your router can sometimes help solve connection problems.
Another user reported that enabling UPnP on his router fixed his connection problem.
A user reports:
My firewall was causing the problem. I allowed all internet access through F-Secure Internet security. Then made the network connection as directed by Files. It worked fine. I then set my Internet access back to normal and the network connection remained and worked normally.
Users of Mac OS X 10.5 (Leopard) or later should disable network proxies (System Preferences -> Network -> (choose the appropriate interface) -> Advanced... -> Proxies). It appears that the Finder's WebDAV is completely broken with proxies enabled. Or better still use Cyberduck.
You receive a copy error message when trying to download a file larger than 50 MB using Windows Explorer on Windows XP SP2 or later.
The error message may be similar to one of the following:
Cannot Copy FileName: Cannot read from the source file or disk.
Error 0x800700DF: The file size exceeds the limit allowed and cannot be saved.
This error is caused by a "security" feature in Windows. The only known work-around is to update a key in the Windows' registry (see http://support.microsoft.com/kb/900900 for instructions).
A better solution is probably to connect to Files using a web browser or Cyberduck.
If you don't have a local Wi-Fi network, but your computer is Wi-Fi enabled, then you can still connect to Files by setting up an adhoc (also known as "peer to peer") Wi-Fi network. To do this:
See: http://www.home-network-help.com/ad-hoc-wireless-network.html
Or: http://www.informit.com/articles/article.aspx?p=1077907

Files relies on the iOS to read Office documents so support is as good (or bad) as it is when viewing these files in Mail or Safari.
Settings can be accessed by tapping the "gear" icon at the bottom of Files' main window.
Yes, you can set a Passcode lock in Files' settings to prevent casual access to Files on your iPhone.
You can transfer documents of any size to Files. Most documents can also be viewed regardless of size, including large PDF documents.
However due to the limited memory available on iOS devices some documents may fail to load. The size limit in these cases depends on the document content and the free memory available on your device (newer devices have more memory).
If you find that a large document fails to display a work-around is to split the document into smaller sections before transfer. Or for images try resizing the image down to 3000x3000 pixels or less.
iPhone: To display the navigation bar in the document view just tap the screen and the navigation bar will appear. Then click the "back" button (top-left hand corner) to close the view and return to the previous list of files.
iPad: Tap the action button at the top-right of the document toolbar. Choose "Close" from the popup menu. Alterantively, just tap the selected document in the folder view.
You can delete files on the phone in three ways:
To zoom in most iOS apps you use two fingers and do a "pinch" gesture. e.g.
If characters are not displayed correctly when viewing text documents you may need to change the text encoding Files uses for the document. Files supports most common text encodings. To change the text encoding while viewing a text document:
Note that you can set an application-wide default text encoding in Files' settings. It is also possible to add custom text encoding names to the list.
You can re-download any purchase for free from the App Store. For more information please see: http://support.apple.com/kb/HT2519
By default iTunes will backup your iPhone, iPod touch or iPad each time you perform a sync. The backup includes all application data, including any data you copy to Files. However you can disable automatic iTunes backup of your device by changing a hidden setting in the iTunes preferences.
Note: this will disable automatic backup of all data on your iPhone, but still leaves you the option to perform manual backups. To perform a manual backup right-click, or control-click, on the iPhone, iPod touch or iPad in iTunes under Devices and choose "Back Up".
To disable automatic iTunes backups enter the following command:
Mac: 1. Quit iTunes 2. Open Terminal.app 3. Copy and paste the following line, then hit return:
defaults write com.apple.iTunes AutomaticDeviceBackupsDisabled -bool true
To reverse the process just repeat but use "-bool false".
Windows: 1. Quit iTunes 2. Open a Windows Command Prompt (Press Win+R and type "cmd") 3. Type or copy the following command:
"%CommonProgramFiles%\Apple\Mobile Device Support\bin\defaults.exe"
write com.apple.iTunes AutomaticDeviceBackupsDisabled -bool true
Also see http://support.apple.com/kb/ht1766
This currently isn't supported by Files or by iOS.
Unfortunately iOS has a fixed limit of 10 items which can appear in the "Open In" menu.
You will need to delete other apps which handle the file-type you are viewing until Files appears in the menu. We are as frustrated about this as you are - hopefully it is something Apple will address in the upcoming release of iOS 6 later this year.
If you experience crashes with any of our apps you can submit a crash report via email. This will help us track down and fix the problem.
The crash reports are stored on your iPhone, iPod touch or iPad at the time of the crash. When you sync your device with iTunes, the reports are copied to your computer to the following location:
If you are using a Mac:
Where ~ denotes your home folder.
In OS X Lion or later the "~/Library" folder is not visible by default. To view it use the Finder's "Go" -> "Go to Folder" menu and enter "~/Library".
If you are running Windows XP:
If you are running Windows Vista:
The crash report log files will start with the name of the application and contain a date stamp. Look for crash reports starting with "Files", "FilesPro" or "DocumentsPro". You can send crash reports to our support email address.
To delete individual items when viewing the browser history use the swipe gesture, then tap the "Delete" button which appears.
To delete all items either:
In both cases you'll be asked to confirm the action.
File types which are displayed by the browser (images, html etc) are by default opened in the browser when you tap the link. To download these types you must tap and hold on the link, after a moment or two a popup alert will appear giving you the option to "Open", "Copy" or "Download" the link. Tap "Download" and the file should start downloading.
If you get a download called "login_verify2" or somesuch it just means your login has timed out and you need to start again.]
Files uses the standard Mail interface and accounts to send attachments. If necessary please set up your Mail account in the iPhone's Settings application.
To import attachments from Mail you use iOS's document sharing menu:

Note: images attachments are handled differently. You must first save the image to your "Camera Roll", then import the image from your "Camera Roll" to Files using the "Import Media" edit action in Files.
You can upgrade to the Pro features using an In-App purchase. These purchases can be found in the Files' settings under "Upgrades".
Our iOS apps use the standard App Store EULA provided by Apple: http://www.apple.com/legal/itunes/appstore/dev/stdeula/
This permits developers to collect anonymous usage information (see section b).
Our apps collect anonymous data so that we can track usage. However we do not track any personal information or any data related to your personal use of the app (for example file names etc).
This is the data we collect:
Device version; iOS version; App version; Current language.
This information helps us determine things like when the is time right to drop older iOS versions and devices; how many active users we have; how widely used translations are etc.
The only data iOS developers receive from Apple are sales numbers, so additional, anonymous, data from active users is very useful and helps us improve our products.
