Yes—this is possible, but the most practical answer from the community is to do it before importing into Lightroom. If you move files after import, Lightroom’s catalog links can break unless you also update the folders inside Lightroom.

Two workable approaches were suggested:

1. Use a script that reads each photo’s capture time from metadata and creates a new subfolder whenever the gap between consecutive images exceeds your chosen threshold (for example, 5 seconds). A Python script was specifically suggested for this.

2. Use Adobe Bridge for faster filesystem-based browsing than Lightroom. Bridge can create and work with stacks, and it operates directly on files without import. However, based on the answers, it may not automatically stack ordinary burst sequences the way you want, so it’s less certain for full automation.

If your goal is true folder creation by time interval, a metadata-based script is the clearest solution. If you just need faster culling and viewing, Bridge may help. In either case, organize first, then import into Lightroom.
