I am having serious problems with this phone!!! I have just changed from an iPhone to the HTC Desire and want to put music onto the phone. I have all my MP3 files in folders on my PC HDD. So for example, I have a folder called AC/DC, in that folder I have a folder called Back in Black and in that folder I have all the MP3 files from the AC/DC Back in Black album. All me MP3 files are structured in this way. I have created a folder on the Desire called "Music" and have dragged and dropped all the folders from my PC into this folder. I find that the phone finds and plays the first 10-15 albums but ignores the rest. According to the memory information my 16GB SDCard now shows that a full 3GB has been used - so the files have been transferred. When I look at the card on the PC the files are not showing on the card. I have tried using HTC Sync and Double Twist and NOTHING works!!!! I am seriously regretting losing my iPhone for this HTC model. Should I be putting my MP3 in folders? Should they be put in a folder called Music? What am I doing wrong? Please help if you can.
