For certain folders in hdd, usb thumbdrive or external hardrive, sometimes windows vista didn't show the filenames for the files, in this case you could only see icon.
This is cause by windows vista mistakenly assumes that you want to hide the filenames as a pictures and videos folder
To solve this:
1. Right click on any blank area on your folder and select customize this folder
2.Select Pictures and Videos as folder type
3. Hold Alt key on the keyboard, untick Hide File Names
