In the Open menu you can choose to merge two or more EasyView-files simply by holding down Ctrl while clicking on the desired files and the press “Merge”.

You will then get the option to open these in a new document or in an existing document. You can also choose to embed the measurements ( "Embed the destination document") in the document or if you want to link to it ( "Use links").

When you do this you will get the option to "Join Identical Channels". For example, maybe you have used the same logger for several measurements and like these to be presented as one channel. You can select which properties should match the channels to be aggregated, such as serial number.
