保存場所を変更した「画像の認識」方法について

If you have moved the image files to an external drive, you just need to tell Lightroom where you moved them to. In the Folders panel, right-click on the top-most folder that you moved and select "find missing folder" or "relocate folder" as appropriate. Then navigate to the folder's new location. Everything (folders and images) below that folder will be auto-corrected.

Lightroom knows the difference between (a) images in missing folders and (b) missing images. You need to fix the missing folders first.

Since C with Lightroom 6.14 installed uses SSD, we wanted to reduce the capacity, so we moved the “image file” to the external HDD.
In order to recognize multiple images, it is possible to recognize all the multiple images by applying “Search” to the first image in the case of images that are usually taken continuously, but this was not possible this time. 検 索 Searching about 100 images one by one is difficult.

Also, please give me advice on how to deal with such cases.
