Shareboxed
The most common way to share a file today is a link to a cloud drive: Google Drive, Dropbox, OneDrive. It feels free, because you already have the drive. But a drive link and a sharing link are different tools, and using one for the other is how folders end up readable by people whose names you have forgotten.
A drive link is an open door
When you share from a drive, you are not sending a file. You are granting access to a place where the file lives, and that grant does not expire on its own. Six months later the link still works, the folder has grown, and "anyone with the link" now includes everyone it was ever forwarded to. Every audit of a shared drive finds the same thing: dozens of links nobody remembers creating, all still open.
A share should end by itself
A Shareboxed link is built the other way around. It carries exactly the files you picked at the moment you picked them, it expires after days rather than existing until someone remembers it, it can carry a download limit and a generated password, and it can be revoked with one click. When it ends, everything about it is deleted. The question "who still has access?" stops existing, because after a week the honest answer is nobody.
Keep the drive, fix the sharing
This is not an argument against cloud drives, and Shareboxed is not asking you to leave yours. The app uploads into Google Drive, OneDrive, Dropbox and iCloud Drive directly if that is where a batch should live. The argument is narrower: when the goal is to hand files to another person, use a link with an ending. Your drive is for keeping. A share is for giving, and gifts should not come with a permanent key to your house.
