Removing duplicate photos in OneDrive manually can be a time-consuming task, especially if you have thousands of images stored across multiple folders. To start the manual process, log in to your OneDrive account and systematically review each folder. You can sort the files by name, size, or date to help identify duplicates. Once spotted, you must compare each file's properties--such as file size, format, and resolution--to confirm they are truly duplicates before deleting them. However, this method is not only tedious but also prone to errors, as it is easy to overlook subtle differences or miss files buried in deep directories. 

To simplify this process, the Cigati OneDrive Duplicate Remover Tool offers an efficient solution. This professional software is designed to automatically scan your OneDrive storage, identify identical or similar images using advanced algorithms, and remove them safely without affecting your original data structure. The tool supports batch processing, saving you time and reducing the risk of accidental deletion. It is especially useful for photographers, designers, and users with large photo libraries who want to maintain organized and clutter-free cloud storage. By using Cigati's tool, you can streamline your OneDrive, free up valuable storage space, and ensure a more efficient photo management system.
