ContinuMail Converter 0.2.2

Parallel byte-range scan

The dry-run scan (CLI scan and the desktop app's pre-conversion scan) now parses each mailbox as several message-aligned byte ranges across CPU cores instead of one sequential pass.

  • ~3–4× faster on large archives (a 4.5 GB Gmail export scans in ~13 s instead of ~47 s), with no slowdown on a single very large folder.
  • Bounded, size-independent memory during a scan — large messages spill to a temp file rather than residing in memory, so scanning a multi-GB archive no longer grows memory with the file.
  • Identical results — counts, size estimates, dates, and warnings are byte-for-byte unchanged from the previous scan.

Fixed

  • "Import category colours" no longer hangs when the colours already exist in Outlook.
  • Thunderbird .msf reading no longer fails on a reparsed folder (the table-rebuild fragment is now folded into the real table, so flags/tags come across).

Install (Windows): download ContinuMail.Converter_0.2.2_x64-setup.exe below and run it.
