+Upload and Downloads
+====================
+
+The operations of uploading files to pithos as objects, and downloading
+objects from pithos as a file are presented in this section.
+
+Enter file context
+
+.. code-block:: console
+
+ $ kamaki
+ [kamaki]: file
+ [file]:
+
+Upload a file or a directory
+----------------------------
+
+First, check the files at the current directory
+
+.. code-block:: console
+
+ [file]: ! ls -F
+ file2upload.txt
+ dir2upload/
+ [file]: list
+ pithos (36MB, 5 objects)
+ trash (0B, 0 objects)
+
+.. note:: the `!` symbol is used to run host shell commands
+
+Upload `file2upload.txt` to remote container `pithos`
+
+.. code-block:: console
+
+ [file]: upload file2upload.txt pithos
+ Uploading /home/someuser/file2upload.txt --> pithos:file2upload.txt
+ Done
+
+Check remote container `pithos` to confirm
+
+.. code-block:: console
+
+ [file]: list pithos
+ 2 KB file2upload.txt
+ 2KB info.txt
+ D video/
+ 11MB video/tk1.mpg
+ 12MB video/tk2.mpg
+ 13MB video/tk3.mpg
+ [file]:
+
+Attempt to upload a whole directory, fail and retry with correct arguments
+
+.. code-block:: console
+
+ [file]: upload dir2upload pithos
+ /home/someuser/dir2upload is a directory
+ | Use -R to upload directory contents
+ [file]: upload -R dirupload pithos
+ mkdir pithos:dir2upload
+ Uploading /home/someuser/dir2upload/large.mov --> pithos:dir2upload/large.mov
+ Uploading /home/someuser/dir2upload/small.mov --> pithos:dir2upload/small.mov
+ Done
+ [file]: list pithos
+ D dir2upload/
+ 1GB dir2upload/large.mov
+ 1MB dir2upload/small.mov
+ 2 KB file2upload.txt
+ 2KB info.txt
+ D video/
+ 11MB video/tk1.mpg
+ 12MB video/tk2.mpg
+ 13MB video/tk3.mpg
+ [file]:
+
+.. note:: Try to reupload the files (use the -f option to override) and notice
+ how much faster is the uploading now. Pithos can determine what parts of
+ the file are already uploaded so that kamaki won't attempt to upload them
+ again.
+
+Download an object or a directory
+---------------------------------
+
+Download object `info.txt` as a local file of the same name
+
+.. code-block:: console
+
+ [file]: download pithos:info.txt
+ Downloading pithos:info.txt --> /home/someuser/info.txt
+ Donw
+ [file]:
+
+Download directory `video` as a local directory with its contents.
+We will suppose that a power failure causes the operation to stop unexpectingly
+before it's completed.
+
+.. code-block:: console
+
+ [file]: download -R pithos:video
+ mkdir video
+ Downloading pithos:video/tk1.mpg --> /home/someuser/video/tk1.mpg
+ Done
+ Downloading pithos:video/tk2.mpg --> /home/someuser/video/tk2.mpg
+ <POWER FAILURE>
+
+After we recover the terminal and load kamaki in `file` context, we find out
+that `tk1.mpg` had been downloaded while `tk2.mpg` download is incomplete.
+
+.. code-block:: console
+
+ $ ls -F video
+ tk1.mpg 11MB
+ tk2.mpg 4MB
+ $
+
+Let's resume the download uperations (use -r)
+
+.. code-block:: console
+
+ [file]: download -R pithos:video
+ Directory video already exists
+ | Use -r to resume
+ [file]: download -R -r pithos:video
+ Resuming pithos:video/tk2.mpg --> /home/someuser/video/tk2.mpg
+ Downloading pithos:video/tk3.mpg --> /home/someuser/video/tk3.mpg
+ Done
+ [file]:
+
+Upload all
+----------
+
+.. code-block:: console
+
+ [file]: upload -R -f . pithos
+ Done
+ [file]:
+
+.. note:: Kamaki calculated that all information is already uploaded, there was
+ nothing to be done. If there is was a new or modified file, kamaki would
+ detect and upload it.
+
+Download all
+------------
+
+.. code-block:: console
+
+ [file]: download -R -r pithos
+ Done
+ [file]:
+
+.. note:: Kamaki determined that all files have already been calculated. This
+ operation examines all local files against the remote objects and
+ downloads only missing data.
