Google Photos does not normally preserve your computer folder structure as albums during upload. Uploaded images usually appear together in the main library, sorted by date or modification time.

Based on the answers here, your options are:

1. Create albums manually after upload by selecting photos and adding them to a new album in Google Photos.
2. Use a third-party uploader that scans folders and uploads photos into albums that match the directory structure. One community answer mentions an open-source tool called Jiotty Photos Uploader for Windows, macOS, and Linux.

So, if you want automatic folder-to-album organization, you’ll likely need an external tool. If you’ve already uploaded everything through Google Photos itself, you’ll probably need to sort them into albums manually.
