Some iTunes library files showing as an unknown file type - different files from same import...

Haven't been able to find a similar problem on here, but apologies if this is a repetition of another discussion.
Some of the files in my Itunes library popped up with the little exclamation mark next to them, so I attempted to locate them. It's been a patchy problem since transferring from PC to Mac, but has just been an issue of pointing Itunes to the right file.
However, in this instance when I navigate through to the files in the folder they aren't showing as the same file type as the music that is playing in the library - I just get a blank page icon.
What's confusing me is that these aren't different file types or from different sources. They're maybe 3 tracks out of a whole album that is playing fine, that were all ripped from the same CD at the same time.
I've no idea why the Itunes is seeing some of these files differently. Any ideas?

Looked at in the HD they're all showing as M4P. I'm sure it's the way the software is viewing the files, and not the files themselves. Itunes does offer to find the others, but then does a really crappy job of doing so - missing files in the same album in the same folder.
I've cracked the original file problem by pointing Itunes to the files by going through the MacHD route, so now I'm just wrestling with thousands of missing files that I know are sitting right next to the files that aren't missing!
I might just resign myself to ploughing through and fixing it, sorting the patchy artwork at the same time. If I do a purge at the same time I can convince myself that I'm not wasting my life!

The iTunes Library cannot be saved an unknown error has occurred (-48)

Every few minutes, I get an error message from iTunes that says:
"The iTunes Library cannot be saved an unknown error has occurred (-48)"
Quitting and restarting iTunes doesn't seem to make the error go away. All of my music and movies seem to play just fine - not sure why the error keeps popping up - any clues?
- iTunes library is located in it's normal spot (~/user/music/iTunes/)
- OS 10.8.2
- iTunes 10
- iMac 27" early 2010

Thanks again for the gracious response UV.
You've pointed out a problem...there are a lot of WAV files that I have like unreleased live shows of bands like the Beatles, Neil Young, Miles Davis etc that I've gotten off Bittorrent trading. When I look at the "get info" part of the song in iTunes the details that I've hand entered (dates, venue, song, musicians,etc) does show up.
But when I go back to the actual file itself, many are simply tagged something like "track 1" and the only way I currently keep track of all this is how I organize my library ( Musician or Band folder \ Album folder \ indivual tracks). There are literally thousounds of songs that I've entered data for on these WAV files.
Besides getting my current error problem fixed, has anyone who trades live shows come up with an easier way to organize their music. I understand that I may be in the minority with all my WAV files and that many users simply upload CDS, or mostly buy tracks online which is easier to simply grab the data back if they need from some database. I feel like I'm missing out on something big. Maybe I just need a different program for my particular application (archiving & playing music). ANy ideas from other bittorrent traders of unreleased material?
I am learning more and more about how this all works by the minute, and have taken your advice UV about copying all my current library info and putting it somewhere safe. Hopefully this means everything I've entered up until a few days ago will be fine. Still, I have plenty music waiting for me to hear in FLAC files that need to be decoded into WAV files; but I want to wait to do this until I can be certain all my hard work entering data won't go to waste and my error problem has been fixed.
thanks for all insights - Sonny

My iTunes library only shows purchased songs but i have more music on my iPod if it syncs i lose it all?

My iTunes Library only shows purchased songs from iTunes, i have music on my iPod from purchased and cds i have burnt from my computer, this all used to show up in my library but since having to have a new hard drive in my computer my library only shows purchsed songs. If i want to sync my iPod it tells me i will lose all exsisting music which i don't want to do, can anyone help?

- TransferiTunes purchases to the "new" computer by:
iTunes Store: Transferring purchases from your iPhone, iPad, or iPod to a computer
- Transfer other music by using a third-party program like one of those discussed here:
Copy music from Ipod to new computer...: Apple Support Communities
- When all ths stuff is in your iTunes library, make a backup of the iPod by connecting the iPod to the computer and then right-clicking on the iPod under Devices in iTunes and selecting Backup.
- Last, restore from that backup and then sync as necessary.

ITunes Library cannot be saved. Unknown Error has Occurred (-54)

I have been having the following message appear in iTunes:
iTunes Library cannot be saved. Unknown Error has Occurred (-54)
I created a new library which seemed to solve the problem.... until I plugged in my iPod Classic or tried to Sync my iPhone. When this happened this warning message would come every 10 seconds or so making it a nightmare to do anything as the dock icon would bounce or iTunes would pop up. Can anyone suggest what might have caused this problem and how to resolve it.
Thanks
Matt

Hi pholewinski!
I have a couple of articles for you here that I believe will help you with this issue. The first is an article on advanced troubleshooting, and it can be found here:
iTunes: Advanced iTunes Store troubleshooting
http://support.apple.com/kb/ts3297
If following that article's steps doesn't take care of the issue, you can try the things listed in this article, which is about permissions issues in iTunes:

Sorry! Figured it out. Just took awhile to load.

Error -50 is a very unhelpful generic communications error with a number of possible causes. Something between the drive to which you are downloading and the drive from which it is all coming is not working correctly, which probably leaves several hundred options.

HT4914 I have several songs in my ITunes library that show as ineligible to be uploaded to ICloud, even though most of them were purchased through the ITunes Store. Has anyone else experienced this and figured out why?

I had the exact same issue!! Seriously p*ssed me off when I checked out my ITunes purchased items (via my computer) and noticed that most of the additional tracks listed on my IPhone playlist was listed there too. However, I never authorized any purchases!! (I have actually written Apple Support asking for a full refund of all tracks listed on my purchased list)
Be careful when you swipe your finger to the left/right on those "additional" tracks on your IPhone playlist... I'm pretty sure that the cloud symbol is an option to download or automatically buy those tracks.
Solution for the problem:
1 - go to your IPhone settings
2 - choose "iTunes & App Store"
3 - go to "Show All" & "Music"
4 - turn off "Music" by moving the bar to the left (it should be a white color once you turn it off)
Should solve your problem :~)

Hello Solid Buck,
Thank you so much for providing the details about the duplicate song issue you are experiencing. It sounds like you would like to remove the duplicate songs that will not play on your iPhone, but when you connect it to iTunes, iTunes only shows you one copy of the song on your iPhone.
In this situation, I recommend deleting the individual songs that do not play directly from your iPhone. I found the steps to do this on page 61 of the iPhone User Guide (http://manuals.info.apple.com/en_US/iphone_user_guide.pdf):
Delete a song from iPhone: In Songs, swipe the song, then tap Delete.
Thank you for using Apple Support Communities.
Best,

TS3683 Not enough space on my Mac HD to back up my iPad. My iTunes library is on an external drive. Can I use this same drive to Back yup my iPad?

I don't have enough space on my Mac HD to back up my iPad. Actually, my iTunes library is on an external drive. Can I use this same drive to Back up my iPad?

1. First make sure iPhoto is not running. If it is, quit it. Use the Finder to copy your iPhoto Library file to your external drive. Unless you've changed it, its located inside your Pictures folder and is named "iPhoto Library".
2. After the copy is complete, start iPhoto while simultaneously holding down the option key. iPhoto will bring up a dialog box. The file in the list is your existing Library on your internal disk. Click the "Other Library" button and navigate to your external drive. Select your freshly copied iPhoto Library file and click "Open". iPhoto will from now on open and work with this library on the external drive.
3. After you've confirmed iPhoto is working properly with the newly copied library you may wish to delete the original library in your Pictures folder to recover the disk space.
Don't forget to keep a backup copy of your library on a separate disk. It's not a matter of "if" your external drive will fail but "when". You need to make regular backups or you'll be sorry someday.

I recently purchased a new PC. I had backed-up my old computer on Carbonite, so I was able to transfer my iTunes library to the new computer when I downloaded my info from Carbonite. Is there a way to restore my playlists?

I recently purchased a new PC. I had backed-up my old computer on Carbonite, so I was able to transfer my iTunes library to the new computer when I downloaded my info from Carbonite, but the playlists are gone. Is there a way to restore my playlists?
Most of my playlists are on my iPod. If I use my iPod to transfer, will the songs double in my library? Also, how do I do this?
Thank you for any & all info you can provide!
Julie

If you had backed up and restored your library properly you should have ended up with the playlists too. Did you import the media folder from the backup drive into a new library rather than restoring the entire iTunes folder?

You really don't give us enough information to say. Maybe you have filled up your hard drive? Are you seeing any error messages (putting them down here exactly as you see them would help greatly).

Hi 845greening123,
If you do not see your iTunes library when attempting to add music to your iPhoto slideshow, follow the steps outlined in the last section of this article -

What do you do when you're trying to sync your music to iTunes library, you receive the message unknown error -54, then your music on your iPhone 5c is left scrambled?

When I first got my iPhone, I was successfully able to add my music to the iTunes library. Over a period of a month, iTunes hasn't been able to "find" increasingly more of my songs. Then this error message began to appear: unknown error (-54). After listening to tech support I backed up my phone and try to restore it. Afterwards I only had on my phone the songs I had bought. So I tried syncing it again. The same error message as stated before consistently shows up. And now my music is scrambled on my phone (since when did Stevie Wonder sing Mean and Enchanted by Taylor Swift???) Has anyone had this problem? It looks like iTunes is messing up my music. Whats the solution?

Hi Memalyn
Essentially, the bare issue is that you have a 500GB hard drive with only 10GB free. That is not sufficient to run the system properly. The two options you have are to move/remove files to another location, or to install a larger hard drive (eg 2TB). Drive space has nothing to do with SMC firmware, and usually large media files are to blame.
My first recommendation is this: download and run the free OmniDiskSweeper. This will identify the exact size of all your folders - you can drill down into the subfolders and figure out where your largest culprits are. For example, you might find that your Pictures folder contains both an iPhoto Library and copies that you've brought in from a camera but are outside the iPhoto Library structure. Or perhaps you have a lot of purchased video content in iTunes.
If you find files that you KNOW you do not need, you can delete them. Don't delete them just because you have a backup, since if the backup fails, you will lose all your copies.
Don't worry about "cleaners" for now - they don't save much space and can actually cause problems. Deal with the large file situation first and see how you get on.
Let us know what you find out, and if you manage to get your space back.
Matt

I can't play my itunes music it shows !this simbol and says the file couln't be find

i can't play my itunes music it shows me ! this sinbol and says the file couln't be find

This happens if the files are no longer where iTunes expects to find them. Possible causes are that you or some third party tool has moved, renamed or deleted the files, or that the drive they live on has had a change of drive letter. It is also possible that iTunes has changed from expecting the files to be in the pre-iTunes 9 layout to post-iTunes 9 layout, or vice-versa, and so is looking in slightly the wrong place.
Select a track with an exclamation mark, use Ctrl-I to get info, then cancel when asked to try to locate the track. Look on the summary tab for the location that iTunes thinks the file should be. Now take a look around your hard drive(s). Hopefully you can locate the track in question. If a section of your library has simply been moved, or a drive letter has changed, it should be possible to reverse the actions.
Alternatively, as long as you can find a location holding the missing files, then you should be able to use my FindTracks script to reconnect them to iTunes.
If the files are nowhere to be found on your computer, but exist on a device, see Recover your iTunes library from your iPod or iOS device.
While deleting & reimporting works when the media can be found the process will delete user playlists, ratings, play counts, date added information and any other metadata not stored in tags.
