The Best Free Softwares for Windows

English  Français  Español  Deutsch  Dansk  Português  中文  日本語  한국어

What is this site about ?

A huge quantity of high quality free softwares exits under Windows Seven and Windows 8. They are doing the same as the best commercial softwares.
How is this possible ?
The secret is that they are made under the GNU General Public Licence. Anyone can modify the source code of these softwares. Anyone can use these softwares. 

Free software is a matter of freedom: people should be free to use software in all the ways that are socially useful. Software differs from material objects--such as chairs, sandwiches, and gasoline--in that it can be copied and changed much more easily. These possibilities make software as useful as it is; we believe software users should be able to make use of them.

Free software is a matter of the users' freedom to run, copy, distribute, study, change and improve the software. More precisely, it refers to four kinds of freedom, for the users of the software:

The freedom to run the program, for any purpose (freedom 0).

The freedom to study how the program works, and adapt it to your needs (freedom 1). Access to the source code is a precondition for this.

The freedom to redistribute copies so you can help your neighbor (freedom 2).

The freedom to improve the program, and release your improvements to the public, so that the whole community benefits (freedom 3). Access to the source code is a precondition for this.

Jahshaka - The video editor Software

LOGO Jahshaka

Imagine if you could...

Edit with flexibility and speed
Create Effects in real time
Animate with unlimited features
Paint and design on moving video
Create music with all the tools the pros use
Work in any format at any resolution

...all while sharing files, projects and clips with users on your network or around the world

All using a single, open source application where the code is yours that runs on practically any workstation

Jahshaka v3.0 will let you do this, and much more. Jahshaka was written from the ground-up to work in different environments, and lets you use the tools you need to get the job done in real time. Thanks to the power of OpenGl and OpenMl you can do this on anything from PC's to Mac's to high-powered Sgi workstations and not have to worry about mixing video, audio and graphics card, installing custom hardware and drivers, or spending millions of dollars for high end speed, power and functionality

Jahshaka uses todays next-generation hardware to do everything in real time, regardless of what box you are running on. Thanks to the power and economics of mass markets, todays pc's come with everything you need to create any kind of media you want. Todays graphics cards would have cost hundreds of thousands of dollars just a few years ago and deliver an unbelievable level of power and speed into your hands. This is the power that drives jahshaka.

Jahshaka's morphing interface allows you to work as a editor when you are editing, to work as a compositor when you are creating effects, as a audio enginer when you are mixing, and as a animator when you are doing 3d. It will even allow you to create your own hybrid interfaces to match your workflow.

This power and flexability has been unheard of, but its coming your way soon. Imagine a system simple enough to edit home videos and mix audio tracks, but powerful enough to edit HDTV, create film effects or animate a flock of seagulls.

Jahshaka fixes many of the compatability and file sharing problems that exist in large facilities today. The ability to run multiple seats of jahshaka off a single server, with full project and media sharing solve the problems of distributed vs shared storage. Everybody can use the same disk-array and work together without the massive slowdowns of having to move large media files around your network. Jahshaka loves multi tasking, multi user, media sharing environments.

Photofiltre

PhotoFiltre is a complete image retouching program. It allows you to do simple or advanced adjustments to an image and apply a vast range of filters on it. It is simple and intuitive to use, and has an easy learning curve. The toolbar, giving you access to the standard filters with just a few clicks, gives PhotoFiltre a robust look.

Its wide range of filters allows novice users to familiarize themselves with the world of graphics. You can find the standard adjustment functions (Brightness, contrast, dyed, saturation, gamma correction) and also artistic filters (watercolor, pastels, Indian ink, pointillism, puzzle effect). There are more than 100 filters to be discovered !

PhotoFiltre uses two types of vectorial selections. The first type uses automatic shapes (rectangle, ellipse, triangle, rhombus, rounded rectangle). The second type corresponds to the lasso and polygon. They both allow a customized form by drawing a shape by hand or using a series of lines. Every selection can be saved into a seperate file, to be used later on.

Other functions :

Image browser Plug-in management Scanning of images using a TWAIN compatible device (scanner, webcam, photocamera) Transparency management for GIF images and exporting them to icons (16, 256 or 16 millions of colors) Advanced text effects (rotation, shading, bevel) Serveral types of contours and textures Blending and assembling of images.

VLC media player

VLC media player is a free (GPL) media player by the VideoLAN project.

It is a highly portable multimedia player, encoder, and streamer supporting many audio and video codecs and file formats as well as DVDs, VCDs, and various streaming protocols. It is able to stream over networks and to transcode multimedia files and save them into various different formats. VLC used to stand for "VideoLan Client", but that meaning is deprecated[1] [2].

It is one of the most platform-independent players available, with versions for Microsoft Windows, Mac OS X, BeOS, BSD, Windows CE, Linux, and Solaris, and is widely used with over 30 million downloads for version 0.8.6.[3]

VLC uses a large number of free decoding and encoding libraries. Many of its codecs are provided by the libavcodec codec library from the FFmpeg project, but it uses mainly its own muxer and demuxers. It also gained distinction as the first player to support playback of encrypted DVDs on Linux by using the libdvdcss DVD decryption library.

VLC is popular for its ability to play the video content of incomplete, unfinished, or damaged video downloads before the files have been fully downloaded. (For example, files still downloading via BitTorrent or eMule.) This is because it is a packet-based player.

The player also has the ability to use libcdio to access .iso files so that the user can play files on a disk image, even if the user's operating system does not have the capability of working directly with .iso images.

VLC supports all codecs and all file formats supported by FFmpeg. This means that DVD Video and MPEG-4 playback as well as support for Ogg and Matroska (MKV) file formats works "out of the box". However, this feature is not unique to VLC, as any player, including MPlayer and xine, using the FFmpeg libraries can play those formats without need for external codecs. VLC does, however, also support codecs that are not included in FFmpeg.

VLC media player has some filters that can distort, rotate, split, deinterlace, mirror videos, create display walls, or add a logo overlay. It can also produce video output as ASCII art.

VLC media player can play high definition recordings of D-VHS tapes duplicated to a computer using CapDVHS.exe. This offers another way to archive all D-VHS tapes with the DRM copy freely tag. An entire library of tapes (or about 50 D-VHS 2 hours long) can be placed on a single terabyte sized hard drive. However, they must be imported by playing the tapes in real time, and can't simply be copied as data files.

Using a FireWire connection from cable boxes to computers; VLC can stream live, unencrypted content to a monitor or HDTV.

Blender - free software 3D animation program

Blender is a free software 3D animation program. It can be used for modeling, UV unwrapping, texturing, rigging, skinning, animating, rendering, particle and other simulating, non-linear editing, compositing, and creating interactive 3D applications.

Blender has a robust feature set similar in scope and depth to other high-end 3D software such as Softimage|XSI, Cinema 4D, 3ds Max and Maya. These features include advanced simulation tools such as rigid body dynamics, fluid dynamics, and softbody dynamics, modifier based modeling tools, powerful character animation tools, a node based material and compositing system and Python for embedded scripting.

Blender has had a reputation as a program that is difficult to learn. Nearly every function has a direct keyboard shortcut, and with the amount of functions Blender offers this results in several different shortcuts per key. Since Blender became open source, there has been effort to add comprehensive contextual menus as well as make the tool use more logical and streamlined. There have also been efforts to visually enhance the user interface, with the introduction of color themes, transparent floating widgets, a new and improved object tree overview, and other small improvements (color picker widget, etc.).

Open Workbench

What is Open Workbench?

Open Workbench is an open source Windows-based desktop application that provides robust project scheduling and management functionality and is free to distribute throughout the enterprise. When users need to move beyond desktop scheduling to a workgroup, division or enterprise-wide solution, they can upgrade to CA's Clarity system, a project and portfolio management system that offers bidirectional integration with Open Workbench.

Comprehensive Project Management Capabilities

Open Workbench is a robust, mature tool for project scheduling and management. It conforms to and supports the underlying ideals of project management while presenting information in a way that is intuitive and easy to learn. Tens of thousands of project managers around the world use Open Workbench to plan and execute complex projects.

All projects proceed through a series of tasks (or stages) during their lifecycle. By using Open Workbench, these critical tasks or stages become more manageable, making projects more likely to succeed. Open Workbench enables project managers to create work breakdown structures (WBS) with tasks and milestones, set baselines, schedule project plans with dependencies, assign resources to tasks, schedule work on tasks over a period of time, adjust the schedule as actual work is recorded, link master and subprojects and schedule resources across them, and conduct earned value analysis.

Advanced Scheduling Functionality

Once the project plan is created, project managers can schedule tasks with assigned resources for completion. For large projects, scheduling can be an intricate process that balances task relationships, resource availability, and task duration. The powerful Auto Schedule feature in Open Workbench is designed to handle just this type of complexity. With the click of a button, the Auto Schedule feature uses an internal set of rules to create a schedule that takes into account task constraints, dependencies, priorities and resource constraints—automatically generating the best method for project completion. When the plan is approved, the project manager can create a baseline, which gives a snapshot of the project and allows revisions to be compared against the original plan.

Flexible Information Views

Project managers have access to a library of project views in Open Workbench, allowing them to customize the information display to their needs. Multiple views are supported, including Gantt and Phase Level Gantt charts, as well as logical, PERT-style displays. Organizations can also define and distribute custom views as corporate standards.

Scope Change Management

Modifications are required when a projects scope changes, whether due to new requirements, lack of resources or time and budget constraints. Open Workbench identifies these potential problems and trends before they affect a project by performing the following analyses:

Critical Path: analyzes isolated dependency networks and tasks with negative float.

Estimated Time to Complete: calculates the estimated usage required to complete a task and ascertains if deadlines will be met.

Earned Value: analyzes the true progress of a project, taking into account the effort expended as well as what has been achieved.

Managers can refine the project schedule based on these analyses and, using the project baseline, compare scope changes with the original plan for detailed analysis. Having the right information to quickly mitigate potential problems is crucial to the successful delivery of work.

Mozilla Firefox - Web Browser

Mozilla Firefox

The award-winning Web browser is now faster, more secure, and fully customizable to your online life. With Firefox 2, they’ve added powerful new features that make your online experience even better.

Features

Improved Tabbed Browsing

We love tabs as much as you do, so Firefox 2 will open new web pages in tabs by default. Each of those tabs has its own close button, but don’t worry - if you accidentally close a tab, just go to the History menu to bring it back from the list of “Recently Closed Tabs.” You’ll never be crunched for space anymore, either. When you have too many tabs open to comfortably fit in a single window, scroll arrows will appear on either side, and a button on the right side will always show you an easy-to-read list of all your open tabs.

Web Feeds (RSS)

What do news headlines, indie rock podcasts, and pictures of kittens have in common? They’re all things that you can subscribe to with Web feeds. Firefox 2 gives you full control over Web feeds, showing you a preview and letting you choose how you want to subscribe. You can use a Firefox Live Bookmark, or a feed reader that you’ve installed on your computer, or through a Web service such as My Yahoo!, Bloglines or Google Reader.

Phishing Protection

Phishing Protection takes Firefox’s security to a new level, helping to safeguard your financial information and protect you from identity theft. When you encounter a Web site that is a suspected forgery (known as a “phishing” site) Firefox will warn you and offer to take you to a search page so you can find the real Web site you were looking for.

Open Source, More Secure

At the heart of Firefox is an open source development process driven by thousands of passionate, experienced developers and security experts spread all over the world. Our openness and active community of experts helps to ensure our products are more secure and updated quickly, while also enabling us to take advantage of the best third party security scanning and evaluation tools to further bolster overall security.

Automated Update

Firefox’s update system always checks to see if you’re running the latest version, and notifies you when a security update is available. These security updates are small (usually 200KB - 700KB), giving you only what you need and making the security update quick to download and install. The automated update system provides updates for Firefox on Windows, Mac OS X, and Linux in over 40 different languages.

Search Engine Manager

You can now quickly add, remove and re-order your search engines in the Search bar. Firefox 2 will also detect when a Web site has a search engine that can be installed, and will install it for you with a single click in the drop-down menu.
