OK. I thought the use case was just a quick file share, and it didn’t matter if the link was still valid months later. Are you still using those files that you shared with ShareX? Are they public links to those files? (The S3 download bandwidth could add up in the worst case)
Control. I’ve used droplr and cloudapp for years and I’m no longer subscribed, the files are probably gone now.
I used ShareX on windows for a while and it was connected to an s3 bucket owned by me. Those files are still there.
