iTunes – delete duplicates and save valuable disk space by organizing your music collection
iTunes - Delete duplicates
The problem with deleting iTunes duplicates
Deleting duplicate songs in iTunes , iPod, iPad or iPhone may look simple but having hundreds or thousands songs makes this task a little bit hard. If you have a large music collection, duplicate files are inevitable.
There is a built-in option in iTunes to delete duplicates in File->Display Exact Duplicates. As the name suggests this option will display the exact duplicates. This means that if your songs are tagged with different artist, album or song name this function will not help much. The other disadvantage is that it lists all files that have identical tags and you should manually review the results and remove the duplicates. While this is not an issue if you have 10-20 items it could be annoying if you have hundreds or thousands. In any case this is a helpful option provided by Apple, but it is hard to be applied on large collections.
Best way to remove iTunes duplicates
The best way to remove iTunes duplicates is to use a dedicated external application. The advantage in doing that is that such application can clean your entire music library and not just the iTunes duplicates. There are plenty of duplicate mp3 finder applications on the market and you should carefully choose the one that works properly and displays correct results. Using an unreliable tool may delete valuable data.
Choosing the best tool to clean iTunes duplicates
A reliable tool should be capable of identifying duplicate songs in ant format regardless of the ID3 tags. This will help in cleaning files that you may have ripped from CD or downloaded from various sources and are not tagged with artist, album and song name. The key factor in choosing a duplicate mp3 finder is to evaluate its search algorithm. If a tool is not properly developed it may reveal false positives and lead to loss data.
Audio Dedupe is an innovative tool that can help with the cleanup of your audio collection. The key advantages of the tool are:
Reliable search algorithm that can recognize audio files in any forma without the need for ID3 tags
High performance – can scan tens of thousands duplicate audio files in less than a minute.
Multiple options to filter duplicate
Option to compare source folder versus target folder in order to merge new songs with your existing library
Detailed report that includes information on the audio quality of every file in order to keep the best version of a song
In-application preview with continuous playback to help easily compare audio quality between duplicates
Comprehensive auto-check option that can immediately select thousands of files based on date, quality, location, size and other properties
Multiple delete options – delete to recycle bin, move to a folder preserving the source’s folder structure for a backup, permanent delete
You can remove duplicate music files from your entire computer in just several minutes and save gigabytes of valuable space on your iPod, iPad or iPhone.
The option to automatically log-off, shutdown, hibernate or stand-by the system after scan is finished will let you leave large scans overnight. After Audio Dedupe completes its work the project will be autosaved in <My Documents>\AudioDedupe_AutoSave.adpf and you can check the results on the next morning.
A grid popup menu item Properties is added and will show windows explorer file properties window.
We have added new Auto Check option to mark “Files with newer file dates”. This may be useful if you are editing your files and you would like to keep the most recent version that you have on your system.
A new option “Show user checked files in bold color” will let you easier distinguish the files that you have checked manually. If you are reviewing all the groups in the list manually it is handy also to track your progress.
One of the handy new features is the enhanced browse for folder dialog. You can now add multiple folders simultaneously. Just mark the folders that you would like to be scanned by ticking the check box near the folder name and click the OK button.
The Duplicate MP3 Finder – Audio Dedupe 188.8.131.52 is released and available for download. The new versions include plenty of new features and fixes. The new in supported audio file format is the added support for 64-bit floating-point WAVE/AIFF files and little-endian AIFF files.
The folder popup menu “Disable self-Scan For This Folder” is useful if you want to scan two (or more) folders against each other. (Available only in the Corporate version)
The grid popup menu item “Check All Except Excluded” will check all files except the excluded ones from the Advanced dialog in Auto-check options or files whose folder was disabled for auto-check.
A lot faster “100% Identical Files” method and a lot faster Check Selected/Invert Selection/Uncheck All when there are a lot of files in the duplicates list.
There are now two separate columns for File Name and Folder so you can easily navigate through files and folder with long names.
The optimised memory usage and allocation results in a faster speed when scanning many files.
And in addition the are also quite some fixes. Some of them are the fixed logging under Windows Vista/7, fixed auto-check when there are folders disabled for auto-check, fixed column sorting on all columns, fixed loading a project causes all file sizes in the results list to be shown as zero.
Audio Dedupe Duplicate MP3 Finder 184.108.40.206 is released. Audio Dedupe besides finding duplicate mp3 files now supports also – AAC, MP4, FLAC, AC3, WavPack (WV), Musepack (MPC) and Windows Media Audio (WMA) file formats. It also adds support for FLAC, WMA and MP4 tags. AIF is now recognized AIFF extension. You can now quickly rename files using F2 or Rename popup menu (only in registered version). Project modified status in program caption is now updated correctly.
In addition to all the new format and fixes we have provided a new Audio Dedupe Corportate version that supports command line options and can output the results in a file.
-src_list <srclistfilename> – specifies a plain text file which contains file names that you want to compare against <targetfilename> files
-target_list <targetfilename> – specifies a plain text file which contains file names that you want to compare against <srclistfilename> files
Note: If you omit -target_list parameter only -src_list files will be scanned
-log <logfilename> – specifies full path file name where the log from the comparison will be saved, e.g. c:\log.txt
-s <similarity> – specifies a similarity in percents. Example: -s 70
-db <dbfilename> – specifies the cache file name to be used or created.
-cachenames – if this option is specified, the program will store file names in cache instead of files checksum
Note: Cache files store audio files information gathered during the preprocessing pass (1st pass) of the scanning process. So if you often scan the same files, using cache file speeds up considerably the preprocessing pass.
You don’t need to create the cache file. Just specify it as a parameter and the program will create it. Or if the cache file from previous scan exists the program will use it. The cache files extension is ADCF (Audio Dedupe Cache File).
