FileSync Provider Failed RRS feed

  • Question

  • I have been using SyncToy for a few months now, and the last time I ran my sync I got the error "Exception During Preview: The file Sync Provider Failed while detecting changes"

    I have three folder pairs set to Echo out the contents of the folders on my machine to a backup drive.
    It does not matter if I am running XP or Vista the same error occurs. (32 bit)

  • Hi  -

    Did you retry - normally we see this error when some temporary move/delete/rename of a directory happened and we are not sure that we are detecting changes correctly? Otherwise can you paste the message from the log and let us know how that looks?

  • I got the same problem. Both systems are running Windoze 7. On one system x64 (left), on the other x86 (right, Plankton). If I start synctoy from the x86-system, it works properly. If I start it from the x64-system (surely the Synctoy x64-version!), I'll get the error.  Here's the log:
