What is a flash file?

Flash files are very small. For example, a typical firmware upgrade file maybe 1 or 2 megabytes in size. This is much smaller than the 400-1,000 megabytes required to store the actual software, which is stored separately on your phone's internal storage drive. A flash file is a type of software program that acts as an executable for another kind of file, usually to replace the original program.

We flash our phones for various reasons, the most common being to install a new version of the OS. But also, if you have a broken screen or water damage, or even just want to try out a new ROM.
