<desc>
<p>Invoking this operation will change the current working directory of

<p>This operation creates a <c>File</c> Object representing a file which
may or may not exist.
For this operation to be independent of the working directory the
supplied <c>FileNameList</c> must represent the absolute name.</p>

<p>This operation creates a new directory in the target objects associated

<desc>
<p>This operation, creates a <c>FileWrapper</c> which represents a file or directory, and
should be independent of the working Directory,
i.e., a full path name must be supplied. Furthermore, the file or
directory represented by the <c>FileNameList</c> must exist.</p>
</desc>

<type>
<v>FTS = File = #objref</v>
<v>Return = ok | {'EXCEPTION', E}</v>
</type>
<desc>
<p>This operation removes the file or directory, represented by the <c>File</c>
object, from the target objects associated file system. If it is a non-empty
directory or non-existing file or directory an exception is raised.</p>
</desc>
</func>
<func>
<name>transfer(FTS, SourceFile, DestinationFile) -> Return</name>
<fsummary>Copy the file represented by the <c>SourceFile</c>from the target object's file system to a file in the destination <c>FileTransferSession's</c>file system</fsummary>
<type>
<v>FTS = SourceFile = DestinationFile = #objref</v>
<v>Return = ok | {'EXCEPTION', E}</v>
</type>
<desc>
<p>If the target object's and the <c>DestinationFile's</c> associated
<c>FileTransferSession's</c> support the same protocol(s) this operation
will copy the file represented by the <c>SourceFile</c> from the target
object's file system to a file in the destination
<c>FileTransferSession's</c> file system. The file is represented by the
<c>DestinationFile</c> object and may not exist.
This operation must be invoked on the <c>FileTransferSession</c>
associated with the <c>SourceFile</c> object.</p>
</desc>
</func>
<func>
<name>append(FTS, SourceFile, DestinationFile) -> Return</name>
<fsummary>Append the file represented by the <c>SourceFile</c>from the target object's file system to a file in the destination <c>FileTransferSession's</c>file system</fsummary>
<type>
<v>FTS = SourceFile = DestinationFile = #objref</v>
<v>Return = ok | {'EXCEPTION', E}</v>
</type>
<desc>
<p>This operation behaves almost like the <c>transfer/3</c> operation. The
difference is that the <c>DestinationFile</c> must exist since the
<c>SourceFile</c> will be appended to the <c>DestinationFile</c>.</p>
<p>Currently, it is not possible to use this operation when the target
object represents FTP.</p>

<v>FTS = SourceFile = DestinationFile = #objref</v>
<v>Offset = long()</v>
<v>Return = ok | {'EXCEPTION', E}</v>
</type>
<desc>
<p>This operation behaves almost like the <c>append/3</c> operation. The
difference is that the <c>SourceFile</c> will be inserted into the
<c>DestinationFile</c> <c>Offset</c> bytes from the start of the file.</p>
<p>Currently, it is not possible to use this operation when the target
object represents FTP.</p>

<func>
<name>logout(FTS) -> ok</name>
<fsummary>Terminate the target object and close the connection to the file system it represents</fsummary>
<type>
<v>FTS = #objref</v>
