USB drives are the most widely used storage devices due to their compact size, large capacity and fast data transfer. It is due to these characteristics that the popularity of USB drives has endured. Due to the large number of files stored on USB drives, there is a high probability of duplicate copies.

These duplicate files can take up a lot of space and cause a lot of problems. As a result, the performance of the USB drive is also affected, resulting in a noticeable slowdown. Therefore, it is important to know the process of identifying duplicate files on USB drives to ensure optimal performance of the device.

Why there are duplicates on USB drive?

Duplicate files on a USB drive can arise from a multitude of situations. For instance, when users handle a large volume of files, it's easy to inadvertently create duplicates during the copying or transferring process. This can happen due to oversight or a lack of organizational measures.

Furthermore, software applications can sometimes generate duplicate files as part of their standard operations. This is particularly common in programs that involve data manipulation or versioning.

Interrupted or incomplete file transfers are another common scenario. If a transfer process is halted abruptly, it can result in partial duplicates on the USB drive.

In some cases, users might intentionally create duplicates for backup or archival purposes, unaware that they already have a copy elsewhere.

Overall, the presence of duplicates on a USB drive is a multifaceted issue with various underlying causes, highlighting the importance of regular maintenance and organization of digital files.
