After further review of this command I have determined that the -r switch doesn't work as expected. Rather than update all sub-folders recursively it only applies to just one level of sub-folders.
I have corrected the issue in the following update.
ffxp5.4.0.3938.zip
Just unzip the flashfxp.exe and copy it to your FlashFXP program folder replacing the existing flashfxp.exe
When issuing the command you'll want to issue it on the folder being updated, so if you downloaded the css folder you'd then want to apply it as such
Code:
/setfolderdate -rc C:\Temp\1and1\css
But if you downloaded multiple folders into C:\Temp\1and1\ you can just as well use
Code:
/setfolderdate -rc C:\Temp\1and1
