Folders describe storage locations; collections can group photographs for a purpose without making another original file. Understanding that difference keeps your library tidy and stops you creating duplicates you did not intend.
What to do
Keep a clear storage structure, then create a project selection using the supported collection tools. Check whether removing an item affects the collection membership or the underlying file before confirming an action.
A folder structure organized by date or event is simple and predictable. Collections then sit on top of it, letting one photograph appear in several groups without being copied.
When to use each
- Folders: where the files live on disk. Good for a stable, boring structure based on year and event.
- Collections: logical groups such as a portfolio, a client selection or a print order.
- One photo, many collections: the same image can belong to a portfolio and a client album at once.
- Temporary groups: a collection for a short task, like a slideshow, can be deleted afterward without touching originals.
- Moving files: do it inside the catalog software, so references stay correct.
Name collections clearly and keep their purpose in mind, so you can find and retire them later.
A mistake to avoid
Do not treat a collection as a backup. A second organizational view is not a second stored copy. If the original file is lost or deleted, every collection that refers to it loses the image too.
A detail worth checking
Check which operations change only organization and which affect storage. Learn the software’s terminology before a large cleanup, and pause whenever a confirmation refers to original files rather than selection membership.
Try this practical check
Create a collection for a small print selection drawn from two folders. Confirm where the originals remain and test how you would find them again. Remove one item from the collection and verify that the file still exists in its folder.
Common questions
Do collections take up extra storage?
Generally no, because they reference existing files. Check how your software treats them if you are unsure.
Can I use collections without folders?
You still need storage locations, so folders remain. Collections add a flexible layer on top.
What happens if I delete a collection?
Usually only the grouping is removed, not the photos. Confirm in your software’s prompts before proceeding.
