I have been managing a OneDrive account with a large number of files accumulated over several years. Recently, I noticed that many documents, images, PDFs, and other files appear to exist more than once. Some duplicates have identical names, while others have slightly different names but seem to contain the same data.

I initially tried checking the folders manually, but this is becoming difficult because the account contains files spread across multiple folders and subfolders. I also don't want to accidentally delete an important file just because its filename looks similar to another one. Has anyone found a reliable way to identify duplicates based on file properties or actual content rather than filenames alone?

I came across SysInfo OneDrive Duplicate File Finder while looking for possible solutions. From what I understand, it can scan OneDrive folders and help identify duplicate files based on criteria such as name, size, type, and content. I am particularly interested in whether this type of approach can reduce false matches when files have different names but identical content.

Another concern is what happens after duplicates are identified. Ideally, I would like to review the results before removing anything and decide which copy should be retained. For a large OneDrive account, having grouped duplicate results would probably make the review process easier than checking hundreds of files individually.

For users searching specifically for an OneDrive duplicate file finder, what factors should be considered before choosing a tool? Does it make sense to compare files using content as well as metadata, especially when dealing with documents that may have been copied or renamed over time?

I am also wondering about the safest removal process. Some tools appear to offer options to move duplicates to the recycle bin instead of permanently deleting them. That seems useful because it provides an additional recovery option if a file is removed by mistake.

If anyone has experience using an OneDrive duplicate remover, I would appreciate some practical feedback. How well does it handle large accounts, nested folders, renamed files, and files with identical content? Also, does the scanning process affect the original OneDrive files, or are changes made only after the user confirms the deletion?

I am mainly looking for a reliable workflow rather than simply deleting everything with the same filename. Any recommendations or real-world experiences would be helpful.
