Missing folders in Library

[joecos55]

My main had drive is a 14tb drive up until a day or so ago I had all my folders there.  My structure is a folder for each year>then each month> Then the photos are imported by date into the month folder.

Now all I have is this

2021

    07

       20

         22

All my other folders are not showing.  They are still on the hard drive and in the all photos they all have the (!) point showing.

I had folders going back to 2010 (20900 photos)

How can I reconnect?  

Thank you

I have over 200,000 photos.  I am thinking about starting new catalogs each year once a project is done I hardly ever have to go back to that job.

Some points to remember:

• Renaming photos based on the syntax YYYMMDD_hhmmss, has benefits, helps with any issues (usually under MACOS) with sorting, as sorting by filename will be sorting by creation date.
• Keywords, keywords, keywords. Helps with sorting, helps with identification, helps with control.
• Collection, place those separate projects in separate collections. 
• Additional folders, some place all photos in one folder, use subfolders to separate work.

and, yes, link may state other than what I stated, those are my opinions, not facts.
