# File System Providers

###### Identifier:

org.eclipse.core.filesystem.filesystems

###### Since:

org.eclipse.core.filesystem 1.0

###### Description:

This extension point is used to provide implementations of the abstract file system API org.eclipse.core.filesystem.IFileSystem. File system implementations control all aspects of querying and modifying a tree of files and directories in some backing store. Each file system extension is responsible for a file system namespace identified by a particular URI scheme.

###### Configuration Markup:

<!ELEMENT extension (filesystem)>

<!ATTLIST extension

point CDATA #REQUIRED

id CDATA #IMPLIED

name CDATA #IMPLIED

>

<!ELEMENT filesystem (run)>

<!ATTLIST filesystem

scheme CDATA #REQUIRED

>

- scheme - The URI scheme of this kind of file system.

<!ELEMENT run EMPTY>

<!ATTLIST run

class CDATA #REQUIRED

>

- class - The fully qualified name of a class that subclasses org.eclipse.core.filesystem.provider.FileSystem

###### Examples:

Following is an example of a file system extension that provides access to file systems using the "gopher" URI scheme.

       <extension id="gopherFS" name="Gopher File System" point="org.eclipse.core.filesystem.filesystems">
           <filesystem scheme="gopher">
               <run class="com.xyz.fs.GopherFileSystem"/>
           </filesystem>
       </extension>

If this extension was defined in a plug-in with id "com.xyz.coolplugin", the fully qualified name of this file system extension would be "com.xyz.coolplugin.gopherFS".

###### API Information:

The value of the class attribute must represent a subclass of `org.eclipse.core.filesystem.provider.FileSystem`.

File system instances can be obtained via the method `org.eclipse.core.filesystem.FileSystemCore.getFileSystem(String)`.

###### Supplied Implementation:

The platform provides a file system implementation for the "file" scheme.
