We have an Azure File Sync deployed on a Windows Server 2012 R2, and after syncing all files to Azure Files we detected that there were a large number of files archived to another disk (with a specific archiving solution), and the sync agent did not unarchive those files before replicating them to Azure. Now we are forcing the unarchiving of those files by doing a "read" of them, but we can't find a way to confirm if once we read those files once unarchived (without modifying anything in them), the sync agent detects them as changed (because of the access date which is new) and will re-sync them to Azure Files.
