Android (EVO) File Structure Information

[David737]

I am looking for a Book, PDF File or Blog with basic file structure information on the using the Android. I recently purchased and love the HTC EVO. This is my first Android phone after over 10 years with the Microsoft Windows Mobile and it predecessor?s. I understood where files were stored in the Microsoft platform. Where are the bookmarks stored, how do I backup this information? Is there a superior file Explorer tool? My Sprint supplied Samsung 8 GB microSD card is readable on my laptop using the USB cable that came with the phone, but when I remove the microSD card from the phone, I cannot read it using a SanDisk HC SD card reader that reads all other 8 GB & 16 GB cards in my Windows 7 laptop computer. Why is this not readable in my laptop? Thanks in advance for you suggestions.
