[O] new to exporting: how to export to a specific location (aromatically?)

[Xebar Saram]

Hi list

im new (in general and to exporting in particular).

I have a few questions:

1.how does one specify a location where exported files go? can one set this per file or perhaps per export type etc?

2. can one auto export files when saved/changed etc?

3. i cant understand the difference so much between export and publishing, apart that publishing is only for html (and not txt etc..)?

Thanks alot
