Copy all sdcard contents to larger sdcard Recently I've run out of room on my small (2GB) sdcard.  What I want to do is copy all the contents of this card onto something a little larger.  I have an FTP server (the one that comes with ES File Explorer) installed on my phone, and that's pretty much the only way I can copy from the card mounted in my phone to a computer or vice-versa (my computer has never recognized my phone's sdcard and only displayes /data).

What's the best way to copy all of it (including hidden files, non-readable files, and apps stored on the sdcard)?
The least tricky way is:

take your 2GB card out of the device, put it into a card reader, and attach that to your computer
copy all contents from the card to an empty directory on your computer
safely remove the card reader, replace the 2GB card by the newer, bigger one, and attach that to the computer
copy the contents of the directory from step 2. to the new card
safely remove that card again, and place it into your Android device

When in doubt about the hidden stuff, use Linux for the copy process. You can even boot it from a LiveCD. From a terminal command, use cp -R /path/to/source/* /path/to/target. On the other hand, if using Windows and you can see the files/directories starting with a dot (watch out e.g. for the .android_secure directory), they should be copied along fine.
