> Indicates whether this FileSystem and 'fs' are the same.

> Implements:
>   isMatch in interface FileSystem

### · getMountPoint | Summary | Top

       public DiskObject getMountPoint()

> Returns a DiskObject representing the point in the directory hierarchy where this file system is mounted. May return null if that information is not available.

> Implements:
>   getMountPoint in interface FileSystem

### · getDisplayName | Summary | Top

       public String getDisplayName()

> Returns the name of this object, as it would be displayed to the user. Note that the display name may be different from the name of this object. If this object no longer exists, returns null.

> Implements:
>   getDisplayName in interface FileSystem

### · getFlags | Summary | Top

       public int getFlags()

> Returns a set of binary flags associated with this object. Use the 'getGetFlagsMask' method to find out which bits of the returned value are significant.

> Implements:
>   getFlags in interface FileSystem

### · getGetFlagsMask | Summary | Top

       public int getGetFlagsMask()

> Returns a mask which indicates which bits returned by 'getFlags' are significant. For instance, if bit 0 of the return value of this method is set, bit 0 of 'getFlags' contains actual information, otherwise, this information is not available.

> Implements:
>   getGetFlagsMask in interface FileSystem

### · getCapacity | Summary | Top

       public int getCapacity(long[] cap)

> Retrieves the the maximum number of bytes of data this file system can hold, as well as the number of bytes currently available on this file system.

> Parameter | Description
> cap | on return from this method, this array will contain the capacity and free space. It must have at least 'FS_GETCAP_LENGTH' elements. The capacity of the file system will be stored at offset 'FS_GETCAP_CAP_OFFSET', and the free space will be stored at offset 'FS_GETCAP_FREESPACE_OFFSET'.

> Implements:
>   getCapacity in interface FileSystem

### · getMaxFileNameLength | Summary | Top

       public int getMaxFileNameLength()

> Returns the maximum length each element of a path name can have.

> Implements:
>   getMaxFileNameLength in interface FileSystem

### · getDir | Summary | Top
