Memo Book Classic - Memo Book can store text documents including attachments within a flexible tree structure in only one single file. Documents from the tree structure can be exported to a new Memo Book-file, to a CHM-file or to a PDF-file, which then contains the selected document structure.
If encryption is activated, all documents and attached files are permanently encrypted and decrypted on the fly as required. Furthermore, the document text can be formatted like in every common word processor.
