The file browser of V-NET is designed for touch devices with small screen sizes. The traditional folder tree structure navigator on the left of the screen is absent and the file browsing can start at any folder inside the file system, which act as the local root (or top) of the sub folder tree to be browsed. The file browser and folder browser is separated in the current system.

The following is a snapshot of the folder browser.

Figure: Folder browser page.

The main menu is under the page navigation bar.

• It shows a few kinds of help information or usage guide related to the current page.
• Expand/Collapse the file system navigator under the main menu.

The floating panel under the main menu is the file system navigator. The path of the local root folder is shown inside of the dark area at its top.

File system navigation is accomplished inside the area under the "Expand Folders", which is called current navigation path, starting at the local root / node. The button for each node is used to open the list of all child nodes of the node on its left. One can select one of the child nodes listed to modify or add the node to the current navigation path. For example, if one tap the "100ANDRO" folder inside option popup in the sample snapshot shown here, the "Camera" node in the current navigation path will be replaced by the "100ANDRO" node. Tap on any node inside the current navigation path will select it as the current node with the child folders under folder selected in the list view below. The relative path (to the local root) of the current selected folder is shown under the "Current" area, which, for the sample view, is "/DCIM".

• Goto the file browser page rooted at the local root folder.
• Refresh statistics about the local root folder.
•  Create subfolder at the bottom of the above mentioned child node list, opened by tapping the button of certain node. An text box and an commit button will appear after tapping it so that the user can set the name of the folder to be created.
• Create the folder with a name given by the content left to it under the corresponding node.

The list of folders under the current selected folder are shown under the file system navigator. For each folder listed, there are a set of buttons for a user to interact with the file system.

• Refresh statistics about the folder. Some folder state dependent buttons listed below appear only after the user initiates the first state probe using this button.
• Goto the file browser page rooted at the folder.
• Start renaming the folder.
• Commit the changed name of the folder.
• Enter the tag editing mode to add, update or delete a tag for the folder. For an existing tag, one can either delete it using the button inside the tag editing mode or set its name to empty and update it.
• Commit the tag of the folder so that it is listed inside of the system wide file system entry points.
• Remove the folder. It appears only when the folder is empty.
