# Scanning

**Scan Types**

There are 4 types of scan:

* *Single Show* – A single show can be scanned manually.
* *Quick Scan* - A ‘clever’ scan that looks in the download directory for shows to scan. It also scans missing episodes from the recent list.
* *Recent Scan* – A scan that looks at all shows that have had an episode aired in the last few days. The number of days can be specified in the preferences.
* *Full Scan* – Scans all shows that are set to be scanned.

**Triggering Scans**

These can be triggered in several ways:

* On Startup
* Via [Command Line](/technical/command-line.md)
* [Periodic ](/menu/preferences.md#scan-settings)(Automated)
* When download/search folder/file changes
* Manually
