The same photograph can be a different file
Phone exports, messaging downloads and manual backups can leave several versions of a photograph. Different filenames can contain identical bytes. Conversely, matching thumbnails may hide differences in resolution, capture metadata or compression quality.
DUPESPACE currently finds exact content matches. It does not label burst shots, crops or similar-looking images as disposable duplicates, and it does not choose the best-looking photograph for you.
Start with a read-only comparison
Open the local analyzer and choose a photo folder. Your browser processes the files without an account or upload. Size filtering narrows the candidates before full-content fingerprint comparison. Large files must still be read, so processing time depends on the device and storage medium.
Results use one representative image per group, with duplicate names and relative paths. Some formats show a type icon rather than a preview; this does not prevent content comparison. Reference order uses modification time and path, not a verified original creation date.
Review the purpose of every copy
One photo may belong to your working album and another to an intentional backup. Both can be necessary even when their contents match. Check each folder’s purpose before deciding what to remove.
The browser creates a report only. For actual cleanup, select the same folder in the Windows app, protect important working subfolders, then scan and review again. A CSV is an audit aid, not an instruction to delete files without revalidation.
Use the Recycle Bin before making an irreversible decision
Test the workflow with a few expendable copies first. Moving files to the Recycle Bin does not necessarily free disk space immediately. Check your retained photographs and albums before deciding whether to empty it. Permanent deletion is not a suitable way to try out a cleanup tool.
