EML files are emails saved from MS Outlook or another mail client in its native formats. Such files are impossible to be read or edited outside email clients. However, you can turn them to simple text documents, by converting EML to RTF. If you want to get the full version of the content stored inside, convert EML to RTF with attachments with the help of Total Mail Converter Pro. The Pro version is unique - it converts emails and all attachment to RTF in one go (most of other email converters just save attached files in the original file type, which is not convenient).
RTF is a format that any document editor can open. It works on commercial packages like Microsoft Word and on open source solutions like OpenOffice. This is a universal document format. Powerful EML RTF converter supports batch function that helps to process a lot of EML files together, setting all parameters one time for the whole scope of originals.
You can select between full and partial mail conversion. Full conversion implies exporting data from each email field to RTF document. Partial mode allows converting data from some specific field. Considering that RTF is one of the heaviest text formats, partial compression will help to create maximally compact mail copies.
This program can save attached files to a separate format, no matter what type they are. It also has additional options for specific kinds of files:
Attached text documents and emails can be converted to RTF
Attached images can be integrated into a converted mail copy
Attached archives can be unzipped and saved locally
Moreover, you can name attachments automatically by a preset template. This will help to keep all the files in proper arrangement. When you convert EML files in batches, often attachments are so messy that it is hard to find the required one. When named properly, they will be easily manageable.
