Checking log files with PowerShell

[gin]

Hi, I use FFS to do various backups, then a powershell script to check on the resultant log files. Specifically, I check the file's LastWriteTime vs CreationTime to see whether the sync was still in progress. If LastWriteTime = CreationTime, then it's still in progress.

This worked well with FFS 6.6. However, recently I had to update to FFS 8.4 and now LastWriteTime never updates even after the sync is complete, despite the fact that the Date Modified you see in explorer is clearly updating. Can anyone advise me on this?
