yellow icon with exclamation point

[alexaa]

I recently (10/19/20) had to replace the drive that all my images resided on.  The database was stored on a different drive and did not change.  I copied all the files from the original drive to the new drive. Today (10/20/20) I noticed every  image in the database has a yellow triangle with a black exclamation point in it.

What does the  yellow triangle with a black exclamation point mean and how do I get rid of them.

Thanks

See: Off-line Folders and Files
You need to relocate the disk so IMatch knows that you have moved all your files on another disk.

Thanks Mario.

Relocated from k: to k: and yellow icons are gone.
