> I am trying to append content to a sftp file. but vfs seems not supports that.
>  
> My test code: 
> {code:java}
> FileObject file = fsManager.resolveFile("sftp://root:xxx@192.168.1.1:22/sftpappend.txt" );
> if (!file.exists()) {
>     file.createFile();
> }
> FileContent content = file.getContent();
> OutputStream outputStream = content.getOutputStream(true);
> {code}
>  
> Error info :
> {code:java}
> org.apache.commons.vfs2.FileSystemException: The file type does not support append mode.
> at org.apache.commons.vfs2.provider.AbstractFileObject.getOutputStream(AbstractFileObject.java:1180)
> at org.apache.commons.vfs2.provider.DefaultFileContent.getOutputStream(DefaultFileContent.java:413)
> {code}
> I checked the source code. seems its easy to support APPEND option in sftp. {color:#FF0000}Why commons-vfs doesn't do that?{color}
