When this occurred, I was not the chief technology officer of the Government of Canada. I was the CIO of CBSA.
In terms of the question that I failed to answer earlier, you asked if it was convenient for me. I don't know how having my files corrupted would be convenient to me in any way at all.
In terms of your other question of how often it occurs and whether it is a common occurrence, I think corrupted files are a common occurrence. As for how often it occurs when different government employees change laptops or computers, I could not speak to that.
