I'm sorry, I've forgot to add which was the cause of this exception,
maybe it will be useful:

I hope it will help you to solve this problem. I think it's a bug in
FTPS implementation.
Thanks.

Good afternoon, dear VFS gurus!
I am currently testing FTPS from vfs-2.0-snapshot and I've managed to
successfully connect to FTPS server, but when I try to check if a file
exists, I'm getting an exception with strange message:
*org.apache.commons.vfs.FileSystemException: Could not determine the
type of file*
"ftps://193.44.23.12:9001/archive/,AMCPROD,derivative_pricing_ssb_cds_20100910_00.xml.pgp,U,20100910A00012022189.txt".

at
org.apache.commons.vfs.provider.AbstractFileObject.exists(AbstractFileObject.java:448)
My code for checking if the file exists is:
FileObject dir = null;
String fileName =
",AMCPROD,derivative_pricing_ssb_cds_20100910_00.xml.pgp,U,20100910A00012022189.txt";
// .... dir initialization
FileObject neededFile = dir.resolveFile(fileName);
return neededFile.exists();
I must say this code works perfect for FTP and SFTP. The problem
appears only with FTPS.
Maybe I've forgot to do something(like enter in passive mode or
something else), or is it a bug in this FTPS
patch(https://issues.apache.org/jira/browse/VFS-264)?
Please advise, it's very important for me.
Thank you very much in advance!
