ownCloud Client

ownCloud Client is an open source, cross-platform and completely free software that provides a graphical user interface for the award winning ownCloud cloud server software.

Features at a glance

Key features include support for the latest upstream ownCloud server release, allows users to access their data from any computer where the ownCloud client is installed, makes sharing data with other people possible, and supports automatic backups, versioning and encryption.

Easy to use graphical user interface

When opening the application for the first time, you must enter the address of the ownCloud server that you wish to connect to, enter the username and password, as well as to set the local folder where the ownCloud files will be synced.

At the end of the configuration process, you will be notified that your entire ownCloud account is synced to the local folder, giving you the possibility to open the respective folder or the ownCloud server in a web browser.

The application resides in the system tray area and will always keep your local and remote files in sync. You can always view how much free space you have left on the server by right clicking the tray icon.

Under the hood, availability and supported OSes

In order to run the ownCloud Client application you’ll have to install the ocsync tool, as well as various Python libraries. The program is written in Qt and you’ll need CMake to compile it from sources.

It’s a platform-independent application that supports the GNU/Linux (Ubuntu, Debian, CentOS, openSUSE and Fedora are officially supported), Microsoft Windows and Mac OS X operating systems, running on both 32-bit or 64-bit hardware platforms.

Bottom line

Overall, the ownCloud Client application is the best tool to synchronize your personal ownCloud server with your computer. All you have to do is to select one or more folders on your PC or Mac and the application will automatically synchronize the files, allowing you to access them wherever you are.

What is new in version 1.8.0:

• Stability and performance:
• As with every ownCloud Desktop Client release, there have been many smaller improvements and updates to the underlying infrastructure. Notable is support for using more parallel requests with ownCloud server 8.0.3 (to be released in a few weeks) and higher, leading to much better up- and download speeds.

What is new in version 1.5.0 Beta 1:

• First of all, we have completely redesigned The Propagator. It's the component that is responsible for actually performing all the changes that earlier phases in a sync run have determined to be required. It is vital that the propagator does things in a clever way, and the new design allows just that. The new propagator writes changes to the sync journal as they happen, and does not rewrite the journal after every run. This means that sync runs can be paused or even terminated, and on the next start, the client will pick up where we left it. This is especially important for the initial sync which may take quite a while.
• Next, we sped up sync runs significantly. If you are using an up-to-date server version, ownCloud Client 1.5 only requires one instead of three round trips to get a simple file uploaded, since the server can now accept the modification time as a header value. This will especially help with small files.
• Another thing this release gets straight is support for remote moves: The old propagator handled them in terms of delete and re-download, which is a bit silly to begin with. Finally, with the new propagator, we can correctly handle moves for what they are, which turns pushing Megabytes of files into a simple mv instruction. In order to detect moves reliably, we now use file IDs next to ETags other meta data, which requires ownCloud 6.0 on the server side.
• When you deleted folders, the old propagator would work strongly recursive, meaning a deletion one-by-one. This had several implications, as the non-atomic way of the old approach was problematic as it allowed for unexpected errors to happen. Also every file would be moved to the trash separately (assuming you had the trash app activated), making restore rather painful. The new propagator does away with all this: If you delete one directory, only the directory with all its structures will be moved to trash. As a side effect, this makes the delete operation on the wire much faster.

Requirements:

• ownCloud
