There are two things that control the location where CaptureGRID saves new photos.
- Photo Download Directory, you can change this in the Options/Preferences window.
- Filename Expression option, which can specify a sub-directory under the current Photo Download Directory
Filename Expression is the one that can change dynamically, so I think you can use this to achieve what you want.
For example, customise the Filename Expression so it uses the session number for a subdirectory, such as:
Here [I] will be expanded to the session number, and [S] will be expanded to the sequence number.
This will result in filenames such as:
… you set session number is set to 1
… you change session number is set to 2
