DVR hard drive space

Does Plex DVR auto-delete oldest recordings if it’s running out of space?

you set up how long to keep, whether to keep etc in the Advanced tab when you setup the recording.

Keep

Set the maximum number of unwatched episodes to keep for the show. Available options:

All episodes
5 episodes
3 episodes
1 episode
Episodes from the past 3 days
Episodes from the past 7 days
Episodes from the past 30 days

Examples:

If you choose “3 episodes” and you currently have 3 unwatched episodes, then when a new episode gets recorded, the oldest existing episode will automatically be removed.

“Episodes from the past X days” refers to when an episode first aired. So, if you record the nightly news and choose “Episodes from the past 7 days”, then after the 7th day, older unwatched episodes would start being removed. Conversely, if you have that setting chosen and you record a repeat airing of an episode that initially premiered a year ago, the episode would not be retained at all (since it was first aired more than 7 days ago).

Tip!: You should really only use the “Episodes from the past X days” options for shows where you’re only interested in retaining current episodes.
Delete Episodes After Watching

Choose how quickly episodes are removed after the server admin has watched them. Available options:

Never
After a day
After a week

For any setting except Never, episodes will automatically be deleted X number of days after the server admin account has watched them.

Warning: This is based on the server admin account. If this value is set and the server admin watches an episode, it will be deleted after X days even if a shared user has not watched it.

It seems like it will automatically delete even if space is available. I was hoping it would only delete when space was needed. So I don’t have to choose how many episodes or days. I really want to keep as many as possible as space allows.

Also, 5 episodes as the max is too low. Should have options for 7 and 10 episodes.

Thanks for the reply.
