I have already done a preliminary review for you, and I hope to help you do a better job.

Based on the PR title and the diff, it seems that the change is fixing an issue related to uploading content to KS3. The change adds a call to Seek function before uploading the content to KS3. This ensures that the file pointer is reset to the beginning of the file, which was not happening previously.

There are no potential problems with this change. However, it is always a good practice to thoroughly test the code after making changes to ensure that everything is working as expected.

As for the suggestions, it would be better to add more details to the PR description, such as the problem that was being fixed and why this change was necessary. Also, it would be helpful to include any testing that was done to verify that the fix works as expected.
