Media Library Items: The Special Helix Ones

It's always a little bit spooky when Google shows 0 results for some of my Sitecore-related searches. I was doing a sanity check in one of my projects to see where the media library Project folder went. I know that this folder, and a few others, come with every base install by default, so I was perplexed as to why the ID of that item was never surfaced in Google.

Here are the paths and IDs of the media library items I'm referring to:

/sitecore/media library/Project
{90AE357F-6171-4EA9-808C-5600B678F726}

/sitecore/media library/Feature
{AA12EEAE-D925-4569-BC39-6092C745FC05}

/sitecore/media library/Foundation
{574EBB19-4A94-44FE-AA79-877DD48C7DA1}

They are the Helix architecture folders.

These items are automatically created in Sitecore via IAR. You can't delete those items, because they'll just get auto-resurrected by the items.master.dat file.

Something interesting I noticed in SitecoreAI is that the per-site media library folders (e.g. /sitecore/content/sites/site-name/Media) are actually what appear to be symlinks to corresponding media library folders in the media library folder itself.

Thumbnail generation is something developers need to keep an eye on during development. SitecoreAI stores the generated items here:

/sitecore/media library/Project/site-name/System, or /sitecore/content/sites/site-name/Media/System, depending on how you look at it.

Yours in trivia,
