PortableApps isn’t the only site from which you can access software that will run on a USB flash drive—but it is free and easy to use. Alternatives include http://www. portablefreeware. com/ and LiberKey.
Insert your USB drive in an open USB slot on your computer. Double-click the PortableApps Setup file in your Downloads folder or web browser. Select your language and click Ok. Click Next. Click I Agree. Select “New Install” and click Next. Select “Portable” and click Next. Select your USB drive and click Next. Click Install. Click Finish.
The PortableApps Platform and App Store may launch on it’s own once the installation is finished.
Click the checkbox next to the apps you want to install. Click Next.
Portable apps are a more popular solution for Windows users, so don’t expect to find as many app options for Mac.
Most recently produced flash drives can house a large number of portable apps.
Consider the number and sizes of the app files you plan to download
