I was having problems syncing Excel files, and I discovered the following. Excel File is on Computer A and B and all sync'd Open Excel on computer A Open Excel on computer B Make a change in Excel on computer A, and close Excel. Wait a minute or so. Close Excel on computer B, without making any changes. Bittorrent Sync will restore the Excel file on computer A to the version before a change was saved!!! This was tough to figure out, but I believe I know what's happening. When you open Excel on computer B, it modifies the timestamp on the file, even if you did not save any changes!!! See this article: http://support2.microsoft.com/default.aspx?scid=kb;EN-US;826741 So how should Bittorrent Sync deal with this? Without some kind of workaround, the changes made in Excel on computer A are lost!!!
