Help Can't see some files when connected to computer?

[Bokxoh]

When I connect my XPERIA X10 Mini Pro to my computer via USB, I click on "Xperia mini pro" and then "Memory Card" and some things show up.

But when I go to my file manager in my phone more things show up, for example, ".demovideo" and ".androidsecure" and more.

Also when I take out my SD card from my phone and put in my computer, the more things also show up.
Is it possible to make to see the more files when I connect my phone to my computer because I do not want to always open the back of my XPERIA X10 Mini Pro because it is bad for its ass.

Sorry for my bad english I am from Hong Kong.

EDIT: Also I have turned on show hidden files and folders and its still not show up.

Interesting. Where do you click on "Xperia mini pro"? I mean: Where does this message show up?

Connect your phone, pull down the status bar, choose "turn on USB storage". Give it a while to connect. Now you'll have a new drive letter in Explorer (assuming you use Windows) - the FAT partition of your SD card. You can also reach this via SE PC Companion's "File Manager" link.

Which files are shown depends on your Explorer settings and whether any of the files and folders on the card are "system" or "hidden" (not the case on my mini pro).
