What is the Previous ITunes Libraries folder for

Hi,
I have the above in MyMusic folder where all my iTunes stuff is?
What is it for?

Each time you upgrade iTunes the existing library is first moved or copied into this folder and given a timestamp of the date of the upgrade. The libray is then updated to work with the new version.
Possible uses for the files:
~ Should the upgrade go wrong you can restore the previous library and try again.
~ Should you lose your library for any reason the most recent copy in that folder is a good place to start rebuilding from, though not as good as restoring from a proper backup.
~ Should you decide you want to downgrade you will need access to a previous version as libraries are not backwards compatible.
If you have a decent backup for your *iTunes Library(.itl)* file and no desire to downgrade iTunes then you can safely delete the folder.

  • What is the best iTunes Equalizer settings for Bose QC15 Headphones?

    What is the best iTunes Equalizer settings for the Bose QC15 Headphones? An image of those settings would be great.

    I'm a bit of an audio geek, so I can tell you that YES whatever sounds right is what you want, but NO those settings are not very good. The general setting is "OK" but the values are extremely out of range. Take that setting and reduce the distance between the sliders and you're getting there. Look for example at how the other iTunes presets are made, the don't go that far from the horizontal middle, and for good reason.
    When you play a recorded song, the song has usually been put through an extensive process of mixing, EQ and mastering before you got it, in order to get the best balance of all frequencies, to ensure the best sound accross a wide range of speakers and headphones, and to ensure the most important details and instruments are audible when played together.
    All speakers are different, and that's where the idea of an EQ for the listener is introduced. The idea is to tweak the overall sound from your music player (iTunes) to compensate for the strengths and weaknesses of your speakers. Which to be honest, is a bit much to expect form a typical music consumer.
    The iTunes EQ has a set of horizontal lines representing 3dB (volume steps) each. In my experience you should not boost or cut more than 6 db at the most - and that's a lot! I stay at around 0-4dB. The extreme options are there to cut noise from bad recordings or emphasize a detail you can't hear very well.
    So here's basic EQ lesson:
    The EQ represents the range frequencies in sound that the human ear can hear. Actually they go beyond that - most people cannot hear the far left and right frequencies. The range of frequencis start at "deep" or "low" frequencies at the left (bass) passing through the Midrange (midtones) in the center, to the (treble) at the right.
    Your speaker has a limit to how many frequencies it can play at once before it starts to lose detail - meaning one sound will drown out in order to make room for another. So don't over-EQ your sound or it'll ruin it.
    How to tweak an EQ:
    1) Start by playing a well-produced piece of modern music  - it'll most likely be well mixed and employ a wide range of frequencies. I'm into heavy metal but for this I'd probably go with some average pop music, because metal is so noisy it gets hard to pick out the details.
    2) Set you EQ to FLAT - zero all accross the board. It'll sound pretty flat and boring unless your speakers are very "flavoured" or "colored" already.
    Sliding any of the EQ bar up, will increase or boost the volume of the frequency the bar represents. You can't really add frequencies that aren't there already - you're just adding noise in that freqeuncy and that will "fill up" the available frequencies on your speaker, causing that "drowned out" effect I was talking about.
    Instead, slide them down from the center, and you're cutting the volume instead. This is better because it'll leave more "room" for the other frequencies. You can always use the Preamp slider at the end if you're worried about loudness (but I wouldn't).
    3) Start by tweaking the 500 and 1K slider. This represents the middle of your ears' range of hearing and the most noticable change. It should most likely go downwards - this will take the "canned" sound out of your music and that'll be apparent quickly. Go ahead and slide that down as far as -6dB.
    4) Now work outwards from the center forming a "v" shape, where the top tips of the V end at the 64 slider and the 8k slider. The very far left and right sliders (32 and 16K) should dip down again to about 0bB. Trust me, these are almost non-important in most music. You can tweak thos last if you feel it's needed.
    5) now it's time to start playing round with the V shape. Go ahead and try sliding the sliders a little up or down between 125-250 and 1K to 4K. You may find that some need to move a lot out of the average "V" shape before the sound is good. This is what my iTunes EQ settings ended up looking like for my Motörheadphones "Motorizer" headphones:
    Hope it helps.

  • Can't get rid of "Previous iTunes Libraries" Banner

    When I opened my iTunes 10.5 it asked me to open a pervoius library for some reason. I tried searching for my most recent library to get it back to normal but now at the top on iTunes it says "Previous iTunes Libraries" How do I get rid of that without any big probelms? 

    Problem solved i found the solution from another dicussions. I hope this helps because it helped me:
    I'm not sure if this is new with iTunes 9, but the words you're seeing at the top of your library are the name of the folder where your "iTunes Music.itl" file is located. If it reads "Previous iTunes Libraries" then you must be using using an .itl file that is located in the "Previous iTunes Libraries" folder, not the normal "iTunes" folder.
    I can't tell you when your iTunes changed to this .itl file, but it could have happened before upgrading to iTunes 9 and you're just noticing now (if I'm right in that this "Title" is a new feature).
    Look around your computer and see if you find another .itl file in the "iTunes" folder. Does it have a more recent date than the .itl file in the "Previous iTunes Libraries" folder? If so, then you can change .itl files by closing iTunes and then re-start it while holding the Opt key (Shift for Windows) -- keep holding the Opt key until you see the prompt, at which point you should select "Choose Library" and navigate out of the "Previous iTunes Libraries" folder and over to the "iTunes" folder and select the .itl file there.
    If the .itl file in the iTunes folder has an older date, then you've probably been using a different .itl file. Find the most recent dated copy and move that to the iTunes folder, then use the Opt-start method to change iTunes to the new file location.

  • Do I need to keep Previous iTunes Libraries?

    In my Music folder, I have one folder called "iTunes," which has 4 items: an "iTunes library," an "iTunes Music Library.xml," an "iTunes Music folder," and a "Previous iTunes Libraries folder." In the Previous iTunes Libraries folder are two files: one called "iTunes 4 Music Library" and one called "iTunes 4 Music Library (Old)." Do I need these? Can they be trashed? I need space and these seem to be duplicates of the iTunes library which exists outside of the previous libraries folder.
    Thanks.
    Terry

    The previous library files are placed there after an upgrade and are not used by iTunes. you can safely trash them.

  • How to get songs that are in "previous iTunes Libraries" folders ??

    I am unable to play scores and scores of songs that were on my iTunes 4.9 playlists now that I have "upgraded" to 7.0 I have a strange icon to the left of the song on my song list and when I go to play the song I get a message that the song cannot be located. The following notes come from iTunes help (see below) and I am wondering if anyone else has lost music and if so.....are they really lost or just misplaced? I would hate to think Apple would insist on an upgrade to buy more iTunes if they are going to scrub away hundreds of your other songs.
    HELP PLEASE
    Note: The library file name for versions of iTunes prior to 4.9 was "iTunes 4 Music Library" for Mac OS X and "iTunes 4 Music Library.itl" for Windows. After upgrading to iTunes 4.9 or later, the older library files are moved to a "Previous iTunes Libraries" folder.

    If the strange icon you refer to is an exclamation point, the problem is that the song files are not in the location the iTunes Library files are saying they are.
    Note that the iTunes Library files do not contain the actual song files but rather a list of references that point iTunes to where the songs are (or rather should be) located.
    So the first thing I'd do is find out just where the files are on your computer. Have a look at this article in the Apple Knowledge Base for some ideas on how to do so.
    Post back and let us know if you're able to find the song files.

  • What is the default iTune Folder Structure for iTunes 10?

    What is the default iTune Folder Structure for iTunes 10? As far as I can tell in windows 7 it goes something like.
    My Music\iTunes\iTunes Media\Music
    Other folders for downloads, pod casts, mobile applications are all in the iTunes Media folder, however the iTunes library database files are located in the iTunes Folder.
    The reason I ask is that I am re-doing my music collection and I set up the folder structure mentioned above, but iTunes re-arranded everything and copied all of my music into the iTunes Media folder.
    Anyone have any idea how iTunes does it by default?

    Here are typical layouts for the iTunes folders:
    If you have upgraded from version 8 (or earlier) to iTunes 9 (or later) at some point, then your media folder (everything inside the red outline) may still be called iTunes Music instead of iTunes Media. The extra Music folder inside the media folder is used if you have allowed iTunes to Upgrade to iTunes Media Organization (iTunes 9) or used File > Library > Organize Library > Reorganize files in the folder "<Media Folder>" (iTunes 10). Depending on your choices for Keep iTunes Media folder organized and Copy files to iTunes Media folder when adding to library plus a little bug in which one build changed the name of the file storing the choice of layout it is quite easy for some of your files to be organized according to one layout and some the other.
    Assuming you're happy letting iTunes organize your files the following steps should tidy things up (should it be necessary):
    1. Select File > Library > Organize Library... > Tick Reorganize files in the folder "<Media Folder>" and click OK. Skip if this option is greyed out (already upgraded) or you prefer the older layout.
    2. Select File > Library > Organize Library... > Tick Consolidate files and click OK. This will bring any files currently organised outside the designated media folder into it.   NB This will create duplicate copies of any file that needs to be consolidated, and you will need to manually clean up afterwards. If space is at a premium try my scripts Unconsolidated to find out what would need moving and ConsolidatebyMoving to move rather than copy it.
    3. Select Edit > Preferences > Advanced tab, uncheck Keep iTunes Media folder organized and click OK.
    4. Select Edit > Preferences > Advanced tab, check Keep iTunes Media folder organized and click OK. This triggers iTunes into reorganizing everything according to your preferences.
    5. (Optional) Close iTunes, rename the folder iTunes Music as iTunes Media then restart iTunes. Check under Edit > Preferences > Advanced tab that the location has automatically updated. If you can't access the media for any reason just undo the folder rename.
    6. (Optional - Windows only) If Windows Media Player has ever had access to your files it may have liberally scattered folder artwork files about which iTunes won't tidy up when it reorganizes things, thus leaving behind a heap of folders with artwork and no media. I've written a script for cleaning this mess up called CleanDeadArt.
    PS If you really prefer the older layout, but it is already in the new one then edit the file called .iTunes Preferences.plist in your media folder and change the integer from 1 to 0 before doing step 3.

  • I opened my iTunes and most of my music was gone, it said "Previous iTunes Libraries" at the top and had playlists from a few years ago (that I've long since deleted). How can I get my old library back?

    Please help!! About a week ago I opened my iTunes to find that all but 200 something of my songs were missing (I had 1,000 something the day before) and all of my current playlists were gone. They've been replaced by playlists that I had nearly four years ago and have long since deleted. It also says "Previous iTunes Libraries" at the top. I am SO frustrated because everything is gone!!!

    Nevermind, once I posted this topic it gave me some helpful related topics on the side and I found my answer! Would have been nice if it could have given me those before I posted this!!! Anyway, if anyone else sees this and is having the problem, press and hold the Shift key while double clicking to open itunes on your desktop, then it will ask you to select a library and just choose the one with the most recent date!! (Use the Opt key instead of Shift for Mac users). I owe alot of thanks to the person on the board that helped me, been frustrated for DAYS!!! THANK YOU!

  • HT5848 What is the sampling rate and codec for iTunes Radio. Is it lossless encoded?

    What is the sample rate and codec for iTunes Radio? Is it lossless encoded?

    I have to agree with you.  There are several forum discussions on bit rate being as high as 256 kbps but I don't see how it could be more than 96 kbps based on the poor sound quality I'm hearing.  I'm comparing it to an internet radio station that is 128 kbps and sounds much better.
    Am I missing something?

    If the files are already there, they'll never be overwritten when you visit a

    Here are some general tips to keep your Mac's hard drive trim and slim as possible
    You should never, EVER let a conputer hard drive get completely full, EVER!
    With Macs and OS X, you shouldn't let the hard drive get below 15 GBs or less of free data space.
    If it does, it's time for some hard drive housecleaning.
    Follow some of my tips for cleaning out, deleting and archiving data from your Mac's internal hard drive.
    Have you emptied your Mac's Trash icon in the Dock?
    If you use iPhoto, iPhoto has its own trash that needs to be emptied, also.
    If you store images in other locations other than iPhoto, then you will have to weed through these to determine what to archive and what to delete.
    If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!
    Delete any old or no longer needed emails and/or archive to disc, flash drives or external hard drive, older emails you want to save.
    Look through your other Mailboxes and other Mail categories to see If there is other mail you can archive and/or delete.
    STAY AWAY FROM DELETING ANY FILES FROM OS X SYSTEM FOLDER!
    Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.
    Again, archive to disc, flash drives, ext. hard drives or delete any old documents you no longer use or immediately need.
    Look in your Applications folder, if you have applications you haven't used in a long time, if the app doesn't have a dedicated uninstaller, then you can simply drag it into the OS X Trash icon. IF the application has an uninstaller app, then use it to completely delete the app from your Mac.
    To find other large files, download an app called Omni Disk Sweeper.
    Download an app called OnyX for your version of OS X.
    When you install and launch it, let it do its initial automatic tests, then go to the cleaning and maintenance tabs and run the maintenance tabs that let OnyX clean out all web browser cache files, web browser histories, system cache files, delete old error log files.
    Typically, iTunes and iPhoto libraries are the biggest users of HD space.
    move these files/data off of your internal drive to the external hard drive and deleted off of the internal hard drive.
    If you have any other large folders of personal data or projects, these should be archived or moved, also, to the optical discs, flash drives or external hard drive and then either archived to disc and/or deleted off your internal hard drive.
    Good Luck!
