Duplicate Finder & Remover is too limited
I purchased "SysInfo OneDrive Duplicate Finder & Remover" from this company to clean a large personal family one drive storage reaching its size limitation (about 900gb). The tool does find duplicates directly in the cloud, which is useful. However, the complete lack of search criteria makes it of limited use. In my case it returned returned ≈15,000 results—many of which are legitimate repetitions (e.g., a folder.jpg per album) or irrelevant due to minimal size, or some I may want to live with for any reason (keep that work for later, review the details etc). You cannot restrict the search by size, extension, or keywords. You run the scan and get everything. Then you must browse many pages of results in a web interface that you cannot sort (size, file type, etc.) to manually select deletions. So you cannot priotise the largest files for instance. In practice, it is of limited use for this type of needs. Support was very reactive and polite, but that cannot make up for the product’s core shortcomings. I requested a refund, insisted politely, and was told I would not receive one because that's how the tool is and that's what I would get. A future version may improve it. In the meantime I'll find another solution.
