Do you know how to use macros in download path?
This can be set as default in the Settings- Downloads - New Download - Set Default Download folder setting, or somewhere else?
It is better to use group list in the left panel and define download folder for every group separately:
- You can right click on a selected group, choose "Group properties" from the context menu and change download folder if needed.
- If you want to use different settings, you can create separate group and select this group in "Add download" dialog window.
- You can even use group settings for just one site, if you select the group for the site using "Site Manager" tab.
If you want to have the best results, you should do some tests on your own.
