This is probably a godsend feature for folks who deals with large files and keeps running out of disk space on your on laptops.
Project Infinite is Dropbox’s answer to managing large and many files on the cloud. Say for example if you have just copied multiple large size files onto your Dropbox folder, typically Dropbox will sync these new files across your devices elsewhere when you turn them on, and it becomes a problem if you work on devices with limited storage capacity i.e. laptops.[
Previously you could use selective syncing option but when you are managing a lot of files on multiple devices, things can get a little messy. Project Infinite solves this issue by placing a file-like stub (or some prefer to call it placeholder) in your Dropbox folder which takes up no space, zero bytes of data. The stub works like an actual file and syncs on demand, except Dropbox downloads it in the background and when you are done, it gets uploaded back to the cloud.
Nothing stays on your drive unless you want a local copy, which you can call from the dropdown menu. Dropbox didn’t mention this in the announcement video but you will be able to select the local copy and make it into a stub again.
Dropbox, however, did not mention a release date or if Project Infinite will be available to free accounts but we suspect it might just be rolled out to Pro and above subscribers.Learn more from Dropbox
