The File System is a logical arrangement, usually in a hierarchial tree, where files are placed for storage and retrieval. It may consist of one or more file stores.

- Method Detail
  - getFileStores
```
OSFileStore[] getFileStores()
```
    Get file stores on this machine
    Instantiates an array of OSFileStore objects, representing a storage pool, device, partition, volume, concrete file system or other implementation specific means of file storage.
    
    Returns:
    
    An array of OSFileStore objects or an empty array if none are present.
  - getOpenFileDescriptors
```
long getOpenFileDescriptors()
```
    The current number of open file descriptors. A file descriptor is an abstract handle used to access I/O resources such as files and network connections. On UNIX-based systems there is a system-wide limit on the number of open file descriptors.
    On Windows systems, this method returns the total number of handles held by Processes. While Windows handles are conceptually similar to file descriptors, they may also refer to a number of non-I/O related objects.
    
    Returns:
    
    The number of open file descriptors if available, 0 otherwise.
  - getMaxFileDescriptors
```
long getMaxFileDescriptors()
```
    The maximum number of open file descriptors. A file descriptor is an abstract handle used to access I/O resources such as files and network connections. On UNIX-based systems there is a system-wide limit on the number of open file descriptors.
    On Windows systems, this method returns the theoretical max number of handles (2^24-2^15 on 32-bit, 2^24-2^16 on 64-bit). There may be a lower per-process limit. While Windows handles are conceptually similar to file descriptors, they may also refer to a number of non-I/O related objects.
    
    Returns:
    
    The maximum number of file descriptors if available, 0 otherwise.
