Change Drive letter of image files in catalogue

I am returning to use Photoshop Elements after a long absence and some loss of cognitive functions due to an infection; recently proved when trying a complex Excel sheet, many days spent clearing up my initial messup! Don't get old and ill!

However to return to the current problem.

I have moved last year, outside Elements a large number of image files; several thousands in 109 folders.

There now reside in:-

Acer/I/Scans

I opened the 2019 catalogue and found the following:-

//ALAN-HP/User//ALAN-HP/Usernetwork_drive$< !'Scans1091853104I:builtin_driveK /G

Does this mean that the catalogue is looking for the images in G; drive?

If so can I change this to I drive.

It would be quite a job to re-catalogue all those images so I hope there is way to restore this catalogue to my Elements 2021 setup.

Note I have read an earlier question of mine but to be honest I don't think it applies to this problem:-

Any advice please?
