Let’s say you want to open some office documents such as spreadsheet on a cybercafe. If the cybercafe is using licensed software, you can be certain that you won’t find Microsoft Office installed on the computers because the license is just too expensive and mostly people go to cybercafe to play games, check emails and web browsing.
Or probably the Microsoft Office installed on your computer is unable to run and you urgently need to open a document file when you cannot get help at the moment to fix the problem. You are left with the choice of either to use some of the online cloud based office suites such as Google Docs, Windows Live Office, Zoho, ContactOffice or simply run any of these 5 portable free office suites directly from your USB flash drive.1. LibreOffice Portable
LibreOffice is free and is based on OpenOffice that is compatible with files created from Microsoft Office which makes it a great alternative. Unlike other free office suites, LibreOffice even provides an official portable version directly from their website instead of taking the risk in downloading from unknown or untrustworthy sources. The portable version of LibreOffice contains Writer (Word), Calc (Excel), Draw (Visio), Impress (PowerPoint), Base (Access) and Math.
Installing LibreOffice portable is really easy. All you need to do is download the installer, run it and extract it to any location on your hard drive or to a USB flash drive. There is a shortcut for every components but you can also run the LibreOfficePortable.exe where you get a window with a selection of the components to run.
2. Kingsoft Office Suite Free Portable
