Remarks
Constructs a new file system that is identified by a URI
This method iterates over the FileSystemProvider#installedProviders() installed providers to locate the provider that is identified by the URI URI#getScheme scheme of the given URI. URI schemes are compared without regard to case. The exact form of the URI is highly provider dependent. If found, the provider's FileSystemProvider#newFileSystem(URI,Map) newFileSystem(URI,Map) method is invoked to construct the new file system.
Once a file system is FileSystem#close closed it is provider-dependent if the provider allows a new file system to be created with the same URI as a file system it previously created.
<b>Usage Example:</b> Suppose there is a provider identified by the scheme "memory" installed:
Map<String,String> env = new HashMap<>();
env.put("capacity", "16G");
env.put("blockSize", "4k");
FileSystem fs = FileSystems.newFileSystem(URI.create("memory:///?name=logfs"), env);

NewFileSystem(IPath, ClassLoader)
Constructs a new FileSystem to access the contents of a file as a
file system.

static member NewFileSystem : Java.Nio.FileNio.IPath * Java.Lang.ClassLoader -> Java.Nio.FileNio.FileSystemParameters
- path
- IPath
the path to the file
- loader
- ClassLoader
the class loader to locate the provider or null to only
attempt to locate an installed provider
Returns
a new file system

Remarks
Constructs a new FileSystem to access the contents of a file as a file system.
This method makes use of specialized providers that create pseudo file systems where the contents of one or more files is treated as a file system.
This method iterates over the FileSystemProvider#installedProviders() installed providers. It invokes, in turn, each provider's FileSystemProvider#newFileSystem(Path,Map) newFileSystem(Path,Map) method with an empty map. If a provider returns a file system then the iteration terminates and the file system is returned. If none of the installed providers return a FileSystem then an attempt is made to locate the provider using the given class loader. If a provider returns a file system then the lookup terminates and the file system is returned.

Remarks
Constructs a new file system that is identified by a URI
This method first attempts to locate an installed provider in exactly the same manner as the #newFileSystem(URI,Map) newFileSystem(URI,Map) method. If none of the installed providers support the URI scheme then an attempt is made to locate the provider using the given class loader. If a provider supporting the URI scheme is located then its FileSystemProvider#newFileSystem(URI,Map) newFileSystem(URI,Map) is invoked to construct the new file system.
