Not all devices have external storage, right? If so, then I should not be taking any chance on that, right? By the way, what's the benefit of using VFS in addition to having the capacity of storing a file larger than 64K? >From my understanding, use of VFS can slow down the performance in accessing/reading/searching data, right? So, it's better to use resource database instead and break down the file into 64K chunks (iff possible). Please advice.

So far i have tried to work with large file and put in external card then access using VFS as raw data. some reference suggest me to work like that and its fine for me. any other idea?
