Q:
When I import music into my iTunes library it seems to be getting imported twice and I’m ending up with duplicates. For example, one of my music folders has ten MP3 files and one M3U file. When I drag-and-drop that folder to add it to my iPod touch, it adds the MP3 files twice. I am using Windows Vista. If I remove the this M3U file and drag the same folder, the files are only added once. This just started happening with the latest upgrades to iTunes and it only happens on my Vista machines, not my XP Machine. What is happening and how can I stop iTunes from doing this?
- Fred
A:An M3U file is actually not a music file itself, but is rather a playlist of your tracks. Depending on what application you may have used to organize your music in the past, M3U files can often get created automatically in each folder to group tracks for other applications. If you open up an M3U file using an application like Notepad and take a look inside you will likely see nothing more than just a listing of your MP3 files.
iTunes does not normally care about M3U files, and will not create them. However, in those cases where you actually want to import them as playlists into your iTunes library, you can do so manually by using the File, Import option on your iTunes menu.
The most likely cause of the problem in this case is that the more recent version of iTunes on the Windows Vista computer is importing your M3U file in addition to the MP3 files whenever you drag them in. Previous versions only imported M3U files if you did so manually, however iTunes 8 appears to collect them alongside your MP3 files during the normal import. The result is that it imports the MP3 file itself directly, and then imports all files referenced in the M3U file. Since the M3U files in each folder likely contain a list of all of the tracks in that folder, you simply do not need to import these files.
The simplest solution would be to go through your music folder structure and delete all of these M3U files unless you are using some other application to manage or play your music that specifically requires them. You can quickly search for and clean out all of the M3U files simply by using the Windows “Search” option to locate files that end in an M3U extension, and then selecting them all and sending them to the Recycle Bin.
If you need to keep your M3U files for some reason, then the other option to avoid importing them into iTunes would simply be to use the Windows “Search” function to locate your MP3 files instead, and then drag those search results into iTunes as a single group of files.
Will a 3G AV composite video cable work with my iPod nano 4G?
- Paul
A:The short answer is yes. While Apple changed the specifications for the video out connector with the 2007 iPod models, they have not made any further changes to the video interface on the 2008 models beyond removing the ability to charge via FireWire, which is not a charging method used by any of the AV cables that we are aware of. Therefore, any video out cable that was designed for the “3G” iPod nano (with video), the iPod classic, iPhone or iPod touch should continue to work fine with this year’s models.
Note that we strongly recommend purchasing a cable with a reputable brand name from an actual “Made-for-iPod” manufacturer, as there have been some “no-name” cables on the market that claim video compatibility with the newer iPod models but do not actually work. Usually the best tip-off for these types of cables are unknown brand names and low prices. You can expect to pay a minimum of $30 for a good, new set of AV cables, as the licensing and authentication requirements make it virtually impossible for a third-party manufacturer to sell them for any less than this price and still make a profit.
I have bought a new computer and plan to give my old computer to my brother-in-law who wants the disk space cleaned off. I want to transfer my library to my new computer and erase it from the old one. I have backed up my iTunes library using the iTunes “Back up to Disc” feature and have also copied my “My Music” folder directly to a folder on an external hard drive. How should I go about transferring this information to the new computer? Can I “Restore” my library to the new computer from the backup disk? Should I just overwrite the “My Music” from the external drive onto the new computer? Do I have to worry about the new computer not seeing my iPod (“home” computer issues)? Should I set the iPod to sync manually before deleting the library off the old computer? Thanks!
- Alice
A:If you have a copy of your entire “My Music” folder on an external hard drive and all of your music is stored in the default location under the “My Music” folder (normally “My Music\iTunes\iTunes Music”), then the simplest method is to just copy the entire “iTunes” sub-folder structure right back to the corresponding location on the new computer. If you’ve already run iTunes on the new computer, it will have created this folder structure with an empty library, but you can safely overwrite this unless you’ve already manually imported new music into it.
In this case, since you are restoring the entire library exactly “as-is” with the same database and related files, the version of iTunes on the new computer should basically pick up everything as it was on the old computer, including your playlists, ratings, play counts and your iPod sync settings. iTunes stores information on any associated iPods within the library database itself, so it will simply recognize your iPod normally on the new computer without any reconfiguration required.
The only settings that are not stored in your iTunes library database are most of your iTunes preference settings. You can dig up your iTunes preference files and copy them over separately if you really want to (they’ll be hidden down under your home folder’s “Local Settings\Application Data” on the older computer), but it’s generally far simpler to just pull up your iTunes preferences window and quickly go through them again for any settings that you’re concerned about. Most of these preferences will not affect your library organization or your ability to sync your iPod, but are usually concerned with things like importing CDs, using the iTunes Store and playing back your content on your computer.
The music folder on my hard drive shows a sub-folder for each album. When I added the entire folder to iTunes, they’re listed in the library under one unknown album and not grouped together by artist at all. How do you group the songs back together as albums?
- Doug
A:The most likely cause of this problem is that your songs do not contain any actual album or artist information within the tracks themselves.
When iTunes imports music, it does not at all care about the name of the folder that it is coming from. Instead, it looks inside the MP3 file headers for something called an “ID3 Tag” which stores information such as artist, album, track name, and so forth. If an MP3 file doesn’t contain any information in a certain field, then iTunes has no way of knowing which album its from and just considers it unknown.
The best way to solve this in your case would be to get the tags filled in before you import your music into iTunes. There are applications which can fill in these tags based on your file and folder names for you automatically as a batch job. Check out either MP3tag or Tag&Rename for a couple of good options to help you with this.
Once the tags are properly sorted out, you can then import your music into iTunes and it should be able to organize the artist and album information properly for you. If any information is still missing at that point, you can fill in the tags via iTunes and it will also write this information back into the files themselves for future reference.
iTunes shows songs in my library, but when it goes through the sync motion the songs don’t appear on my iPod nano. Any ideas why?
- Sean
A:There are some settings in iTunes that control which songs from your iTunes library are synchronized to your iPod automatically, and depending on how these iPod sync settings are configured will determine whether new songs are added to your iPod automatically or not.
To configure these settings, you must connect your iPod to your computer and then select it from the iTunes “Devices” section at the left-hand side of the screen. This will display the Summary screen for your iPod.

From this screen, ensure that the setting to “Manually manage music and videos” is not selected. When this option is selected, NO music is transferred to your iPod automatically—instead you must transfer tracks to your iPod manually by dragging them from your iTunes library and dropping them onto the iPod icon in the Devices list. If you want to return to synchronizing songs automatically, you will need to uncheck this box and click the “Apply” button in the bottom-right corner of the iTunes window.
If the “Manually manage…” box is not checked, then it is possible that you are instead only synchronizing selected playlists to your iPod. In this case, only tracks that are in those playlists will be transferred to your iPod during an automatic sync. You can check on this by choosing the “Music” tab at the top of the iPod summary screen.

If “Selected Playlists” is chosen on this screen, the only songs that are contained in playlists with a checkbox beside them will be transferred onto your iPod. In this case you must either choose “All songs and playlists” to have iTunes sync your entire library, or ensure that those songs are contained within one of the selected playlists.
Frequently, the “Selected Playlists” setting is used for situations where your music library is larger than your iPod’s capacity. In fact, iTunes itself will offer to create a playlist of music to fit on your iPod when it detects that you have more music in your iTunes library than will fit onto your iPod. If this is the case, then you will not be able to choose “All songs and playlists” as this would try to sync more content than you would be able to fit on your iPod.
Note that you can use Smart Playlists to automatically select content from your library based on search criteria and choose these for synchronization to your iPod as well, however. In fact, iTunes automatically provides a “Recently Added” Smart Playlist which selects tracks added to your iTunes library in the past two weeks by default. If you select this playlist for synchronization to your iPod, then any new tracks you import into your iTunes library will automatically be added to your iPod during the next sync and will remain there for two weeks (the default scope of the “Recently Added” Smart Playlist), after which they will be removed unless you’ve placed them in another playlist which is synced to your iPod.
You can also adjust the “Recently Added” Smart Playlist or create alternative Smart Playlists to automatically include newly-imported tracks for synchronization to your iPod, and even limit them to a certain size to ensure they fit onto your iPod. Use File, New Smart Playlist to create a new Smart Playlist, or select an existing Smart Playlist and choose File, Get Info to edit its settings. For example, the following is a modified version of the “Recently Added” Smart Playlist which excludes videos and podcasts and limits the total size to 1GB of content:

My iTunes library is on an external hard drive that was plugged into an older desktop computer running Windows XP. I just bought a new computer that runs Vista and downloaded iTunes. When I plugged in the external hard drive, I was able to see all the albums, but the playlists had vanished. Also, iTunes on the new Vista computer does not recognize my iPod and tries to synch out the entire library which I do not want. When I plug the HD back into the old desktop, everything is still intact. So my question would be how would I get the new version of iTunes to keep the old playlists, and to recognize that my iPod was synched using that library?
- Mike
A:Although you may be storing all of your content on the external hard drive, the iTunes library database is still most likely located in your “iTunes” folder under “My Music” on your computer’s C: drive. It is this database that contains information such as playlists, ratings, play counts, and your iPod configuration information.
When you connect your external hard drive to the old computer, it of course reads the original iTunes library database for the information, and simply accesses the media from the external hard drive. On the new computer, a new and different iTunes library database is being used (created when you first started iTunes on that computer), which of course does not contain any information at all by default. Any content listed in that library database on the new computer is most likely a result of iTunes searching out and importing tracks from the external hard drive automatically, as it would do for any new library.
The correct solution here is to copy the iTunes library database over to the new computer. You can accomplish this simply by shutting down iTunes on both computers and then copying the entire “iTunes” folder and everything in it from the “My Music” folder on your old Windows XP computer to the corresponding “My Music” folder on your new Vista machine. You can safely overwrite any folder that is already on the Vista machine, as this simply contains the new library that was created when you first ran iTunes on that computer.
You will also want to ensure that the drive letter used by the external hard drive is the same on both computers, since your iTunes database will have a full path to each media file, including drive letter. While iTunes can sort this out for you if your music was properly organized by iTunes in the first place, it’s generally far simpler to ensure that the drive letters are the same. If your external hard drive is assigned a different drive letter on the new computer, you can change it by going into your Control Panel’s “Administrative Tools” section, choosing “Disk Management” and then right-clicking on the external hard drive and choosing “Assign Drive Letter.”
Once you have copied the iTunes library database over and have the external hard drive connected with the same drive letter that was used on the original computer, you should simply be able to restart iTunes and it will automatically pick up the new library database with all of your playlists and other information intact, and be able to locate the media content on the external hard drive.
More information on how iTunes stores its library database and content when using external hard drives can be found in our iPod 201 article, Managing your iTunes Library on an External Hard Drive.

Just got an iPod Nano 4G and I’d like to get earbuds to control playback. Wondering if the V-Moda Vibe Duo controls the Nano or any other alternatives to Apple’s still unreleased earbuds, thanks.

About a year ago I purchased a new computer because my old one crashed. I have about 5 years of music, pictures, movies and other files on my ipod from my old computer. I recently bought a new ipod and am wondering if it is possible to move my songs and data from my old ipod to my new computer/ipod without access to my old computer. thanks!
