When you download songs, have you ever realized that in a terrible internet environment, clicking the download button several times can result in storing several identical MP3 or other audio files on your device, thereby consuming your storage space?
Similar situations can also occur during synchronization, backup and restore, handling email attachments, file renaming, and even file format conversion, even when you do not intend for duplicates to be created. Faced with these scattered audio files, you might wonder whether it's worthwhile to invest your time in organizing them.
Do duplicate MP3 files use much storage space?
Yes, they do. First of all, let’s have a clear consciousness about MP3 file sizes. When you download songs, it's not just about the audio's length that is related to the storage space.
Music enthusiasts often prefer higher bitrates for better audio quality when downloading. But how much space it will require? Let’s take a 4-minute song as an example.
• Medium bitrate MP3s (192-256 kbps): A 4-minute song in this range occupies approximately 6 to 10 MB of storage.
• High bitrate MP3s (320 kbps): It can use about 10 to 14 MB of storage per song.
Moreover, advancements in audio encoding technologies brings better audio quality but more storage consumption.
• AAC/Opus at 256 kbps: Uses at least 12-14 MB of storage.
• FLAC: Demands 15-25 MB of storage.
In practical terms, when you download 100 songs with varying quality settings, over 20 duplicates, on average, can unintentionally creep in due to various reasons mentioned at the beginning. If you have no habit of regularly finding and deleting duplicate files, they can easily consume several gigabytes of your storage space over years of accumulation. Well, this can be a piece of bad news for small disk space users.
These duplicate MP3 files not only worsen storage constraints but also pose a significant risk to your computer's performance. Space shortages can lead to slower operation, potential data loss, and even system crashes.
Why do you need a duplicate MP3 file finder?
After reading the previous section, you might think, “Oh, just a few duplicate MP3 files. I can manually check and delete them”. But, is that approach truly effective?
Traditional manual process requires you to visually inspect your music library to spot duplicates by comparing filenames or song properties one by one. Or, you need to utilize search and sorting tools in File Explorer or Finder to identify duplicates based on file attributes.
However, using these methods to find and delete duplicate MP3 files comes with limitations and drawbacks. Firstly, they can be time-consuming and prone to errors, especially with extensive music and audio libraries containing various file formats like .flac, .m4a, .m4p, .mid, .mp2, .mp3pro, .mpc, .ogg, .ra, .rm, and more, making manual checking a strenuous task.
Moreover, there's a notable risk of unintentional data loss during manual file deletion, and these methods may struggle to efficiently detect duplicates scattered across different locations on a computer or external drives. Besides, these approaches lack automation for ongoing duplicate file management, necessitating users to regularly repeat the process.
