Created a Libre office worksheet in PC1
Synchronized using Synctoy to an external disk
Then in PC 2 , synchronized again and the file was copied to PC2
After making a change in the worksheet in PC1 , repeated the same procedure.
But , when synchronizing PC2 , Synctoy took the old worksheet from PC2 ( older date and time ) and overwrote the newer one on the external disk .
(the worksheets are not read only .)
How is that possible ?
