// Public FileSystem types, that are embedded in filesystem: URL and exposed

// Following two types are for TEMPORARY or PERSISTENT filesystems that
// can be used by webapps via standard app-facing API
// as defined in File API: Directories and System.
// http://www.w3.org/TR/file-system-api/#temporary-vs.-persistent-storage
// They are sandboxed filesystems; all the files in the filesystems are

kFileSystemTypeTemporary = blink::WebFileSystemTypeTemporary,

kFileSystemTypeIsolated = blink::WebFileSystemTypeIsolated,
// Indicates filesystems that are mounted externally via
// ExternalMountPoints with a well-known mount name. The mounted
// filesystems can be sandboxed or non-sandboxed. (E.g. Chrome OS mounts
// non-sandboxed removable media folder with a name 'removable', while
// chrome.syncFileSystem mounts a sandboxed filesystem with a name
// 'syncfs'.)

// One can register (mount) a new file system with a private file system type
// using IsolatedContext. Files in such file systems can be accessed via
// either Isolated or External public file system types (depending on
// how the file system is registered).
// See the comments for IsolatedContext and/or FileSystemURL for more details.
// Should be used only for testing.
kFileSystemTypeTest,
// Indicates a local filesystem where we can access files using native
// local path.
kFileSystemTypeNativeLocal,
// Indicates a local filesystem where we can access files using native
// local path, but with restricted access.
// Restricted native local file system is in read-only mode.
kFileSystemTypeRestrictedNativeLocal,
// Indicates a transient, isolated file system for dragged files (which could
// contain multiple dragged paths in the virtual root).
kFileSystemTypeDragged,
// Indicates media filesystem which we can access with same manner to
// regular filesystem.
kFileSystemTypeNativeMedia,
// Indicates media filesystem to which we need special protocol to access,
// such as MTP or PTP.
kFileSystemTypeDeviceMedia,
// Indicates a Picasa virtual filesystem provided by Media Galleries API.
kFileSystemTypePicasa,
// Indicates a synthetic iTunes filesystem.
kFileSystemTypeItunes,
// Indicates a Drive filesystem which provides access to Google Drive.
kFileSystemTypeDrive,
// Indicates a Syncable sandboxed filesystem which can be backed by a
// cloud storage service.
kFileSystemTypeSyncable,
// Indicates a special filesystem type for internal file sync operation
// for Syncable sandboxed filesystems. The file system is overlayed, i.e.
// points to the same sandboxed filesystem as that of kFileSystemTypeSyncable,
// but the changes made with this filesystem type are not recorded for
// further sync.
kFileSystemTypeSyncableForInternalSync,
// Indicates an external filesystem accessible by file paths from platform
// Apps. As of writing, on non Chrome OS platform, this is merely a
// kFileSystemTypeNativeLocal. On Chrome OS, the path is parsed by
// the handlers of kFileSystemTypeExternal.
kFileSystemTypeNativeForPlatformApp,
// Indicates an isolated filesystem which is supposed to contain one
// temporary which is supposed to go away when the last reference of
// its snapshot is dropped.
// This type is useful for creating a blob reference for a temporary
// file which must go away when the blob's last reference is dropped.
kFileSystemTypeForTransientFile,
// Sandboxed private filesystem. This filesystem cannot be opened
// via regular OpenFileSystem, and provides private filesystem space for
// given identifier in each origin.
kFileSystemTypePluginPrivate,
// A filesystem that is mounted via the Privet storage protocol.
kFileSystemTypeCloudDevice,
// A filesystem that is mounted via the FileSystemProvider API.
kFileSystemTypeProvided,
// A media filesystem such as MTP or PTP, mounted as a file storage not
// limited to media files.
kFileSystemTypeDeviceMediaAsFileStorage,
// A filesystem to provide access to contents managed by ARC.
kFileSystemTypeArcContent,
// --------------------------------------------------------------------
// Marks the end of internal type enum. (This is not the actual fs type)
// New internal filesystem types must be added above this line.
