We have attempted to fix the Daylight Saving Time (DST) issue in our current version. Make sure that you are using Second Copy 7 (build 220.127.116.11) or above.
Second Copy includes a few options that are hidden from the user interface. To set these options you need to edit the profiles.dat file. Changing these options is not recommended unless you understand the implications of these changes and are familiar with editing configuration files.
To edit the profiles.dat file:
1. Exit Second Copy by right clicking on the icon and selecting Exit.
2. Open the profiles.dat file in Notepad.
3. Find the [Options] section and add the option described below. If you don't see an [Options] section you can create it at the end of the file.
4. Save the file.
5. Start Second Copy again from the start menu.
profiles.dat file is a hidden file under the folder:
Windows 9x: "\Program Files\SecCopy" (or where Second Copy is installed)
Windows NT4/2000/XP/2003:"\Documents and Settings\<Username>\Local Settings\Application Data\Centered Systems\Second Copy"
Windows Vista: "\Users\<Username>\AppData\Local\Centered Systems\Second Copy"
When you set this option, Second Copy will not recopy the unchanged files due to the 1-hour time difference after switching between the DST times.
