The Trinidad and Tobago Computer Society (TTCS) has put together a collection of nearly 100 Open Source Software for WINdows (OSSWIN) available for download.

Called TTCS OSSWIN, this collection of Free and Open Source Software is for any home or business (i.e. any) user running Microsoft Windows (Windows 10, Windows 8, Windows 7, Windows Vista and Windows XP) on their computers.

You can use your web browser to read detailed information about each program in this compilation : what the program does, its key features, useful related websites, view a screenshot, find links to the program’s website and to download/install the program from the TTCS OSSWIN collection.

The web-based interface allows you to quickly browse the variety of software organised into the following categories:

  • Desktop Applications
  • Educational
  • Games
  • Graphics
  • Internet
  • Server
  • Sound and Video
  • Utilities

Key features of the TTCS OSSWIN

Easy to install
While many Free and Open Source Software are easy to install, some Free and Open Source Software for Windows are made available as ZIP files which require the user to manually extract the files to a directory and then use Windows Explorer to browse to the directory and run the program. The TTCS has created standard .EXE installers for these applications. This allows the user to easily install and uninstall programs in the collection
Easy to browse with Windows Explorer
All of the software on TTCS OSSWIN is in the “Software” folder with subfolders for each of the categories. This makes it easy for those users who are familiar with the collection to use Windows Explorer to browse and install software on another machine.
Software on TTCS OSSWIN is kept up to date at time of purchase
The TTCS OSSWIN is burnt “on demand” for upcoming TTCS meetings and/or email requests to purchase collection either of DVD or on a USB stick. Buyers receive the most recent stable versions of the software at time of purchase.

Use a program like VisualHash or WinHasher to hash your downloaded file to see if it matches the hashes here. If your downloaded file hash is different, then your downloaded file is different from the file the TTCS has published and shouldn’t be trusted.


How to use TTCS OSSWIN

You can use a DVD burner and DVD burning software like IrfraRecorder to burn the ISO file onto a blank 4.7GB DVD.

However, you can use a program like WinCDEmu to “mount” the ISO file to view and access the ISO as if it was an DVD disc in a DVD drive.

Alternatively, you can use 7-Zip to extract the files to a folder on your hard drive or removable storage such as a USB flash drive.


Hardware and Software Requirements for TTCS OSSWIN

This collection of Free and Open Source Software is intended for use on the following versions of Windows : Windows® 10/8/7/Vista/XP.

The software requirements for each program/application varies but if your Windows PC is already running a program that falls in one of the categories (e.g. Desktop Applications, Graphics, Internet, etc) it can probably run the programs listed under that category.

What is Free and Open Source Software?

Free and Open Source Software is software for which the “guts” of the program can be freely downloaded and altered to suit your needs (provided you can do the programming). There are many types of Free and Open Source Software. The difference lies in the way altered versions of the software can be distributed, so, if you customise the software for your own needs, then decide to distribute it, you may be bound by specific terms.

Many Free and Open Source Software projects make ready to install executable versions for various operating systems including Windows.

You can do the following with Free and Open Source Software :

  • Install the software on any number of machines in any environment (home or commercial) without purchasing licence fees for each machine.
  • Obtain and modify the source code and distribute modified versions of the program together with the modified source code. Free and Open Source Software licenses differ in how such source code can be distributed or licensed for others to also do what you have done.
