The develop module can't find the collections folders. The other modules can. Lightroom C 10.1 Any thoughts about this?
Correct, it is not part of the Develop Module. To add that would be a feature request.
That would be at the official feedback site, in the appropriate product, in the idea tab:
And if you want yo go foward with that, see: https://feedback.photoshop.com/conversations/forum-usability-topics/how-to-requesting-features-ideas...
In Library, bring up the catalog panel, select All Photographs, click on the photo in question,
Right click, select Show in Exploer (Windows, Finder if MAC)
(correction) The Collections panel, unlike Folders, can be shown in the Develop module interface - both are shown in Library.
If you have recently clicked on a given Collection (or Folder) and now want to return to that same view, there is also a drop-down menu presented at the left hand end of the Filmstrip, listing your most recently visited 'sources' for that. So that option is presented across all modules and may often not require switching into Library.
Collections are not In folder and are Not folders themselves.
Folders Are Folder Entries on your hard drive where you Store Files.
LrC Collections are just Lists of Image File Names.
Please state what you are actually doing.
Please show us a Screen shot of what you are seeing on your computer.
The Collection section IS IN the Develop module Left hand Side panel just like it is in all the other module.
But it might not be turned on. Right Click on any of the other section headers and make sure it is Enabled.
The Folders section is ONLY IN the Library module.
