Automating Backups with The Bat! E-Mail-Export-Tool

The Bat! E-Mail-Export-Tool — Complete Guide to Exporting Your MailThe Bat! is a powerful, privacy-focused email client for Windows that serves users who want more control over their mail storage and workflows. One of its most useful features is the E-Mail-Export-Tool, which helps you extract messages from The Bat!’s proprietary store into common file formats for backup, migration, archiving, or processing by other programs. This guide walks through what the Export Tool can do, why you might use it, supported formats, step-by-step instructions, advanced options, troubleshooting, and practical workflows for common scenarios.

Why use The Bat! E-Mail-Export-Tool

Exporting mail from The Bat! is useful when you need to:

• Back up important messages outside the application.
• Migrate messages to another email client or service.
• Archive mail for long-term retention or compliance.
• Process messages with external tools (searching, indexing, or legal discovery).
• Share selected messages with colleagues or legal counsel in standard formats.

Exporting preserves message headers, bodies, attachments (depending on format and options), and timestamps, making it suitable for both casual backups and formal archival needs.

Supported export formats

The Bat! E-Mail-Export-Tool supports several common formats. Choosing the right one depends on your goals:

• EML — Individual message files in the standard RFC 822 format. Best for interoperability with most email clients (Outlook, Thunderbird, Apple Mail) and for per-message access.
• MBOX — Single file containing many messages in a sequential format. Useful for importing into clients that accept MBOX or for processing large sets of messages with tools that understand MBOX.
• MSG — Microsoft Outlook message format. Useful when migrating to Outlook or needing tight Outlook compatibility (note: not all metadata may map perfectly).
• PDF — Useful for human-readable archival or legal export. Messages are rendered as static documents; attachments can be embedded or saved separately depending on options.
• TXT/CSV — Exports message metadata or simple text bodies for spreadsheet analysis or lightweight archiving.
• Custom directory structures/ZIP archives — Many export operations let you build folder trees, save attachments to separate subfolders, or package everything into a ZIP.

Preparing to export

1. Backup The Bat! profile folder first. Even though exports are read-only, it’s wise to have a full profile backup before bulk operations.
2. Decide which accounts/folders to export. Exports can target specific folders, multiple folders, or entire accounts.
3. Ensure The Bat! is not performing maintenance (indexing) and that mail stores are not marked as corrupted.
4. If exporting for migration, verify the destination client’s supported formats (EML, MBOX, MSG).

Step-by-step: basic export to EML

1. Open The Bat!.
2. Select the folder (or multiple folders) containing messages you want to export.
3. From the menu, choose the Export feature (location varies by version — look under Tools or Mailbox menus).
4. In the Export dialog, select EML as the target format.
5. Choose destination folder on disk. Optionally enable “create subfolders” to mirror The Bat!’s folder structure.
6. Decide how to handle attachments (embedded in EML, saved separately, or packaged into a ZIP).
7. Start the export and monitor progress. Large mailboxes may take time; check disk space for the resulting files.
8. Verify a sample message by opening the EML file in another client or a text editor.

Export to MBOX (step-by-step)

1. Open The Bat!.
2. Select the folder(s) to export.
3. Open the Export dialog and choose MBOX.
4. Decide whether each folder becomes a separate MBOX file or all selected folders merge into one file.
5. Choose encoding options (UTF-8 is typically safe) and attachment handling.
6. Start export and verify by opening the MBOX in the destination client (e.g., Thunderbird) or an MBOX viewer.

Advanced options and tips

• Export in batches: Break large folders into smaller selections to avoid timeouts and corrupted outputs.
• Preserve folder structure: Use the option to recreate The Bat! folders on disk so imports maintain organization.
• Attachment handling: If your goal is legal discovery or complete archival, export attachments separately and keep a manifest (CSV) mapping messages to attachment filenames.
• Timestamps and metadata: Check export settings for preserving original Received/Date headers. Some formats preserve these better than others.
• Filtering: Use The Bat!’s search and message selection tools to export only messages that match certain criteria (date range, sender, subject, flagged).
• Automation: If you need repeated exports, consider scripting with The Bat!’s command-line tools (if available in your version) or use macros to speed repetitive tasks.
• Compression: ZIP large exports to save space and make transfers easier. Keep checksums (SHA256) for integrity verification.

Migration scenarios

• Migrating to Thunderbird: Export folders to MBOX or EML; import MBOX via Thunderbird’s ImportExportTools NG or drop EML files into a mailbox folder.
• Migrating to Outlook: Export to MSG for best compatibility, or to EML and use third-party import tools. Verify calendar/contacts separately—mail export does not cover these.
• Archival to PDF: Export to PDF when preparing human-readable archives or legal exhibits. Ensure attachments are included or extracted and saved alongside PDFs.

Troubleshooting common issues

• Missing attachments after export: Check attachment handling options (embedded vs. separate). Some formats require explicit inclusion.
• Corrupted export files: Re-run export in smaller batches. Verify source message store integrity in The Bat!.
• Incorrect character encoding: Use UTF-8 where possible; test a few messages with non-Latin characters before exporting a large set.
• Folder structure not preserved: Enable “create subfolders” or use the option that mirrors the mailbox tree.
• Slow exports: Close other applications, disable antivirus temporarily (if safe), and export to a local SSD rather than network storage.

Verification and validation

After export:

• Open several sample EML/MSG/MBOX files in the target application to confirm content and attachments.
• For archived exports, compute checksums (SHA256) for files or ZIPs and keep a manifest listing exported folders, file counts, and checksum values.
• For legal or compliance use, document export settings, date/time of export, operator name, and tools/software versions used.

Example workflows

• Simple backup: Export each account to a dated ZIP of EML files with attachments saved inside. Keep one local and one off-site copy.
• Migration to Thunderbird: Export each folder to an MBOX per folder, then import MBOX files into Thunderbird using ImportExportTools NG.
• Legal discovery: Export messages as PDF for readability and EML for metadata preservation. Save attachments separately and create a CSV manifest.

Final notes

The Bat!’s E-Mail-Export-Tool is a flexible way to extract messages for backup, migration, or archiving. Choose export formats based on your target environment: EML for broad compatibility, MBOX for client-level imports, MSG for Outlook, and PDF for human-readable archives. Prepare by backing up your profile, test on a subset of messages, and verify exported data before deleting or relying on it.
