Try using a file copy manager. I use supercopier on all of my windows machines (xp and 7). Always get better transfer speeds and haven't had any problems yet. I've transfered several multi-gigabyte avi's to and from my tablet without issue.
Ok, I'm learning. I have NirSoft but don't see that plug-in anywhere,,,,,,,,,,,,,,,, Nor do I see it the System32 folder (if that's where it should be)?
I'm not sure I follow you. Are you having the same issues? Do you have DivX installed?
I don't have DivX installed (I use Xvid), so I don't know if it should be in system32. If you are on W7 x64 and DivX installs a 32-bit plug-in in the system folder, it will probably in C:\Windows\SysWOW64, not in C:\Windows\System32. This might also explain why you might not see the plug-in. Try running ShellExView with the /wow64 command line parameter (as mentioned on the original download page).
