Before sending a Mac project, use Finder to search the project folder for image files, compare likely copies by name, size, and appearance, then inspect every candidate before removing or excluding it. Finder can narrow and sort the files, but it does not provide a one-click exact-duplicate report for a project folder. Treat its results as a review list, and keep the original project intact until you know which files the project actually uses.

Start with the project’s asset folder

In Finder, open the project folder or the specific location where its image assets are stored. Search from there so the results stay relevant to the handoff. Enter a broad term in the search field, press Return, then use the plus button to add a Kind criterion and choose Image. Apple documents Finder searches by kind and lets you choose whether search criteria must match together; confirm the search scope is the project location before reviewing results.

Switch to List view and sort by Name to bring similarly named files together. Names such as logo.png, logo-copy.png, and logo-final-2.png are useful leads, but do not prove the contents are identical. Sort or inspect the Size and Date Modified columns as additional clues. Finder’s List view can show file details such as size, kind, and modification date. Organise your files in the Finder on Mac

If you need to repeat this review, save the search as a Smart Folder. It saves the search criteria and updates its results; it does not move or copy assets. Give it a name that identifies the project and image search so you can distinguish it from the project’s actual asset folder.

Compare candidates before deciding

For each cluster of likely copies, compare the full filenames, file sizes, and modified dates. Then select the candidates and press the Space bar to open Quick Look. When multiple files are selected, use the arrow keys to move between previews. This makes it easier to catch visible differences such as a crop, color treatment, transparent background, or alternate export. Preview files on your Mac

A matching preview is not proof that two files are interchangeable. They may differ in resolution, color profile, transparency, metadata, or file format, and a project may depend on a particular filename or path. Check the image dimensions or metadata in Preview or Finder’s File > Get Info when those details matter. Keep both files if you cannot verify which version the project expects.

Use a review list with three outcomes: keep, check in the project, and confirmed duplicate. A second image with the same content might be intentionally used in another location, or a duplicate filename might be referenced by the project. Before removing anything, check the project’s linked assets, document references, or export instructions in the app that created it. Finder’s search identifies files that meet search criteria; it does not determine whether a design document or other project uses them.

Separate project files from Photos library duplicates

If the images are managed in Apple Photos rather than stored as ordinary project assets, use Photos’ Duplicates collection. Apple says Photos analyzes the library and may take time to show duplicates; you can select matching groups and merge them. Deleted duplicates go to Recently Deleted, where they can be recovered within 30 days. Remove duplicate photos and videos on Mac

That Photos feature applies to items in the Photos library. It is not a scan of arbitrary folders such as a design project’s exports or assets. For those folders, Finder’s search, sorting, and preview workflow helps you find candidates, but manual comparison remains necessary.

Make a clean handoff

After confirming a redundant file is safe to remove, move it to Trash or exclude it from the delivery copy according to the project’s handoff requirements. Avoid deleting a file just because its name contains “copy” or “old.” If the recipient needs editable source files, preserve every asset the project references and keep the folder structure intact. Open the project from the prepared handoff copy, if practical, and check that its images still appear before sending it.

A dependable Mac review combines Finder’s image search with a visual and project-level check. It helps surface likely duplicates without pretending Finder can determine which files are safe to discard automatically.
