How do I choose one primary photo library?

Define what the primary library is for

Your primary library is the working collection: the place where you add new photos, apply descriptions, make albums, and find images later. It can be a photo application, a well-organized folder collection, or a service that fits your normal devices. Other locations can still hold backups, old intake folders, or shared copies. Naming one primary library reduces the common problem of editing one copy while searching for another.

Compare candidates against your routine

List the devices you use most and the types of photos you receive: phone pictures, camera imports, scans, and images from relatives. Test whether each candidate can display originals at full size, keep dates and captions visible, and let you locate a sample by date or album. Consider storage limits and whether you can get a complete local copy when needed. Select the option you are most likely to open every week, rather than the one with the longest feature list.

Set boundaries before moving anything

Create a simple intake area outside the primary library for new material that still needs review. Decide whether the primary library will hold only personal originals, or originals plus edited versions and scans. Keep shared exports separate from the working collection. Record the library name, its location or service, and the date you adopted it in a note. This makes the arrangement understandable when you revisit it months later.

Verify with a small trial

Add a small, varied sample and check that the dates, orientation, filenames, and any captions appear as expected. Search for one item in more than one way, such as by date and album. Open a full-size image and compare it with the source. Once the trial is satisfactory, bring in new material gradually by month or source. A staged move gives you time to notice unwanted grouping or duplicate behavior.

Before making disruptive changes

• Synchronizing a library is not the same as having an independent backup; retain a separate copy before a major move.
• Avoid merging or replacing large collections until a small trial confirms which copy is being changed.
