Chapter Six — File Functions (continued)
Legato provides a series of SDK functions designed to access and manage file systems and file cloud components. The file system can generally be thought of as volumes that contain folders and files.
This section also covers functions dealing with the storage media in which the file systems reside.
Finally, path scoping is provided by BrowseAddSaveScope and BrowseAddOpenScope covered in chapter 9.
Volumes are a logical way to organize storage hard drives, CDs or network drives. They contain a file system such as FAT or NTFS and may be physical, logical or virtual. For Legato and the application, volumes are either mapped drive letters, for example, C is normally mapped to the primary partition of a computer systems’ hard drive, mapped, such as a network drive mapped to a specific letter, such as ‘X’ or ‘N’. Volumes can also be accessed on the fly without a drive letter mapped by using an UNC (Universal/Uniform Naming Convention) in the form of ‘\\server\share\path’.
File clouds can be mapped by synchronizing an area on the computer’s hard drive, usually located in the user’s data area. While convenient, these methods generally have issues with locking files amongst users.
Finally, another form of cloud access is the Virtual File Cloud (VFC). Those are mounted or attached but only accessible to the current application session.
If the underlying application supports managed file cloud access, Legato provides functions for controlling such services. The embedded service is the Virtual File Cloud or VFC scheme.
The VFC consists of a local client manager and a remote server. The server generally employs an SQL style database to store information on one or more servers, or a cloud.
To use a VFC, it must be attached. This can be done via application settings, command line settings, or from a Legato SDK function. Once attached, VFC connections are attached like a web scheme.
When the VFC is employed, the file browse functions within the application will use the VFC browser rather than the Windows Explorer file browse.
