When file/collection, how can I delete all the related items that are not on my last composition?

Hello, I have a great difficulty using the file/collection a large file I did months ago, because when I use it, the file is created, but it takes 2.5 to space! compared to others of my works, taking almost 1 TB of files, this one is too big and I think by deleting some files, but I don't want to make a mistake, so I wanted to ask here, if it is possible to take a main composition and only do a file/collection of this composition, objects and elements that serve there (the last I made on my account at least, with the elements used on that, because I think that there are many (if not a large part of them) files and elements that are not used in the final version, as scenes of the version beta of my work, the problem is the composition is too long and have a lot of different archives or drop movies then it could take forever to do it manually...

Thanks for reading me! I hope that this is a solution...


It's a two-step process:

1. reduce your project to the desired composition.

2 recover your files.

    You can (and should) get the free mp3tag: http://www.mp3tag.de/en/

    Install mp3tag.  When you install, let it be added to the context menus (an option during installation).

    Open mp3tag and in tools, Options, Tags, Mpeg do option Write ID3v2.3 ISO-8859-1. Those are tags favorite rocket, and once make you it by default, whenever you save tags in mp3tag you will get tags Fuze and respectful.

    Your albums may not be labeled at all, or may be marked in ID3v1, who will not read the "rocket". So he goes to the title, if there is a title tag or file name if there are no tags.

    You can now right click on an album folder and see mp3tag as an option to open it. When you click mp3tag, you'll see the files listed. Put them in order from top to bottom - you can try clicking on the header of the track-number or the name of the header file if they are 01-Track 1. If you can align them up and down, highlight all the and click Dial automatic tools Wizard with the option of leading zeros. Bingo: Track numbers 01, 02, 03, and they will play in the order.

    Sometimes people put numbers to track on the file names and they list in alphabetical order by song title - not good. If the "rocket" Impossible to find track numbers and the name of the file is FirstSongTitle-01 (rather than 01-FirstSongTitle), the "rocket" will play them in alphabetical order by name of file: FirstSong, FifthSong, FourthSong, SecondSong, SixthSong, ThirdSong. Then you will have to put in one of the track numbers.

  • How can I delete all THE pictures from the Iphone 6?

    I am trying to remove all the photos from my Iphone 6. I have had no luck with one of the methods I've tried, including the phone for the Mac, excluding photos of synchronization.

    You have iCloud library enabled? If so photos can be rear sync. If this is not the case, try first to reset the Photos App close pictures completely from the window of the selector app by double clicking the Home button and slide up the photo preview pane until it disappears from the display. Then perform a forced reboot. Hold down the Home and Sleep/Wake buttons simultaneously for about 15-20 seconds, until the Apple logo appears.

    Then open the pictures, select Albums, select Camera Roll, then click Select and run your finger through all the photos you want to delete.

    If the above does not help, please detail what you've already tried. As you noted, photos synced from your computer only can be deleted by "unsyncing" their new.

  • How can I disable all the related links?

    Sounds like an extension not desired may have snuck on your system, perhaps as a ride-along with some free software.

    Try disabling all extensions essential or unknown here (when in doubt, turn off):

    Firefox orange (or the Tools menu) button > addons > Extensions category (in the left column, click on Extensions)

    Typically, a link will appear above at least an extension disabled to restart Firefox. You can complete your work on the tab and click one of the links in the last step.
