Cross-check File Integrity between Online and Local version

[killswitch]

As a user who continuously upload large files (2GB-3GB each), I worry about the integrity of the uploaded files due to unstable internet connection, disk I/O error (External HDD times out), etc. I work in the Game/Film industry and 3D files all studios work with tend to be few hundred megabytes to few gigabytes in size (2-3GB file size). Data corruption is a major major headache.

There should be a column against the file names that indicates some identifier (checksum, MD5, or some value) that shows the local and online files are exactly same and is not corrupted or got changed during the upload process. The "Green Checkmark" icon next the file is merely an indicator that it is uploaded but does it verify that both local and upload file integrity is intact?

This idea is going to need a bit more support.

I work in the same industry and with working remotely have recently run into a couple similar situations. Clients download a few hundred GB of image sequences and a few of the thousands of files are corrupted by the time they reach the other end, creating an awkward situation. This happened most dramatically sending zip files of image sequences that were 50-250 GB. I can't verify the delivery end of the pipeline, but it would really help for me to be able to say with full confidence that the files made it onto Dropbox with 100% integrity and can be synced in a documented way (e.g. using the app) without error. I assumed that the Dropbox app/daemon/service runs a checksum given what it seems to do with splitting up files for transmission anyway, but now I'm not so sure. Would be great to have some documentation about this. In the meantime, I'm back to running my own md5 checksums and supplying a hash file for big deliveries.. not terrible but not ideal.
