Import Scans

You may already have had a library before you set up Mnema, to help you import your existing series Mnema can scan a directory for you. After running a scan, you'll see a quick overview pop up on the import scan page. Showing you how many series you need to process.

Scanner

The scanner is a very simple recursive process:

  1. For the current directory, check if it contains any files at its root.

  2. No ⇒ Get all subdirectories and repeat from step 1)

  3. Yes ⇒ Assume this directory is a series and parse.

Parser

The parser for each series is very, again, simple

  1. Are all files in the directory of the same type (cbz or epub)

  2. No ⇒ Error, Yes ⇒ continue

  3. Parse metadata out of the first file

  4. Parse upstream metadata ids and try to link to an existing monitored series

  5. If a successful link, mark as imported otherwise as queued

After a scan has finished, you can open the scan in the UI. And complete the information for all found series.
