C# – Storage Card Problem In windows mobile

Any time you're working with larger amounts of data, you want to make sure you don't hold the whole thing in memory at once.

You're download pipe is a stream, so you can load the data in chunks. When writing the file to disk you have a stream, so you can write it a chunk at a time.

Think of unloading a tractor trailer into a warehouse. With your stringbuilder solution, you're basically saying, "I'm going to stand at the back of the trailer and I want you to load the entire contents of the trailer into my arms, then I'll take it into the warehouse". You'll be crushed by the load! What you want instead is, "hand me just enough that I can actually carry, then I'll take it into the warehouse, and then come back for the next load".

Most of the files listed above can be stored in the same folder as the application exeutable themselves. As you've pointed out there's no admin account on a Windows Mobile device. Part of the reason for the organization of these files on the desktop is to maintain clean seperation of user settings. Since Windows Mobile devices are designed with a single user in mind there are not such facilities to seperate users. If these were files that were intended to be opened directly by the user (like a word document) then at that point I would suggest storing them in the My Documents folder.

The one file over which I have concern is the log files. You mention they can get large in size. These can also be in the application folder but if they can get large in size you will need to be able to react to the devices storage space getting low (by clearing part of the logs).
