#831 Command line redirection to file does not work

[Anonymous]

The command line from a .cmd file

7z a -r -tzip -wV: B:\T_disk.zip T:\*.* >>7zLog.txt

gives a Deined Access and when showed in console shows as:

C:\Program Files\7-Zip>7z a -r -tzip -wV: B:\T_disk.zip T:\*.* 1>>7zLog.txt
Acceso denegado.

It shows "1>>7zlog.txt" instead of ">>7zlog.txt.

I've seen the .cmd file with a hex editor and it does not shows any "1".
