mEdit is a text editor that, under a conventional appearance, lets you combine diverse documents as only one file. The program comes equipped with all the functions you could ask of a text editor: basic options, text formatting, search and replace utilities, support for metadata, etc.
The metadata can be established individually for each document, independently , even if later they´ll all be in the same file. Each document (called a worksheet in the program) can be shown in tabs, columns or lists. In any of these viewing modes you can delete or copy documents freely, as you need.
