I am testing directory opus.
I have a folder I want to have a exact mirror on my laptop.
There is an issue with folder "modified date"
It always changes to today.
I know I can change the folder date manually by going to properties button at the top. Then using change time section of properties dialog box.
But hate the idea having to match this for each folder in the sync
Is there any options or tricks I can do to Auto enable this for folders that are copied to my destination Lister
The subsequent file must not be considered 'identical' (i.e. same size and modified date).
Or the prompt may be asking you if you want to overwrite a read-only file, which will also cause a similar dialog to appear.
Using Copy UPDATEALL is probably what you want:
Update files in the destination folder (a simple form of one-way synchronization). Only files that either do not exist in the destination, or do exist but are different from the source files, will be copied - other files will be skipped. A file is defined as different if either its timestamp or size has changed - the contents of the file are not compared.
In the default toolbars, you can access it via the menu attached to the Copy Files button, near the top left.
You should find Copy UPDATEALL fast. The Synchronize Panel is slower since it has to collate everything into an interactive list.
You'll also find whichever program you do things in first a bit faster, due to filesystem caching, although that wouldn't account for such a large difference.
I wouldn't recommend using the interactive Synchronize Panel on huge folders (e.g. 10,000+ files) as it's not optimized around that kind of task, but Copy UPDATEALL is fine with that kind of thing.
Interactive sync performance with huge folders is something we might improve in the future, although to be honest we ourselves tend to use dedicated tools like Beyond Compare (or WinMerge if you want a free option) for doing large, complicated, interactive sync jobs. You can integrate them well into Opus so you just click a button in Opus and they open comparing the left and right folders.
