Quicken is a financial program that allows you to track all of your purchases, investments and even tax data. When you install the program you are asked to choose a location on your system where you want to store the installed software. When looking to store the software you will find that someplace on your hard drive is already occupied, in such a case you can install the program on an external device, such as an external hard drive or flash drive. This is helpful if you are trying to save room on the hard drive, but you are not able to use the program on multiple computers when installing this way as there are import files inserted into the registry of the computer that do not travel with you on the flash drive.
Putting financial management program Quicken onto a portable drive allows you to bring it back and forth between work and home computers and to backup Quicken files. As an added bonus as this ensures the privacy of your financial data as it will be always in your hands.
