passhfiles is a PyQt-based application used to browse and manipulate files hosted by a server shielded by a passhport/bastion server. As such, you can remove, rename, edit and/or open files/directories on your remote server (and also on your local file system). You can also drag and drop files from/to your local file system to/from the remote target. As such, passhfiles can be considered as light sftp application.
pip install passhfiles
Installers for the main OS are also available for each release and can be downloaded from github.
