Memo Book is a personal information manager developed by "7tech Limited”. It allows you to store text documents with attached files in a very flexible tree. Some or all of the tree can be exported to a new MemoBook file, an HTML file, or PDF, and all documents and attachments are encrypted and compressed into a single file (*. mbk). It uses a highly secure encryption algorithm (Rijndael256) that allows you to maintain the confidentiality of your data. Moreover, text editor integrated into the program, like MS Word (paragraphs, tables, lists, images, background, URL, alignment, header and footer, etc.) will facilitate your task. For more details, I invite you to download the shareware program that is offered free of charge.
