OneDrive checksum?

Is there a way to check that a large file was uploaded correctly to one drive? sorta like a checksum.

If so how would i check it on both ends.

BTW does the one drive app support resume for upload?

Using the Microsoft Graph API, you can query the SHA1 and SHA256 hashes for a given OneDrive file. In reality, there isn't an off the shelf tool because to access the API you need to provide your MS Account credentials. That's a bit of expert-level coding.

There are (paid) 3rd-party products that sync to different clouds (OneDrive, GDrive, Dropbox, etc.) by using their API's. Some of them can probably check the hashes to make sure files are consistent.

There's no concept of "resuming uploads" for syncing. Cloud storage clients regularly scan their folder contents and compare the files on both ends, their timestamps and hashes to understand what is "out of sync". Unless there's a bug, a partially uploaded file won't be kept because it didn't match the original file's hashes.

If you have network issues, after waiting a while, OneDrive client should try to reconciliate both ends.

I have never had onedrive corrupting an upload (as far as I know).

However, why not simply re-download the file and compare SHAS of it with the original file?

Then if both same, the uploaded file must be ok.

Yes, it would not be much of a sync app if it did not.

True, MS apps are like half-baked cookies, but at least they got this right. Basic functionality guaranteed.
