As author mention-ed, now if I move the file to another folder, the .ts/file.json file IS NOT moved at the same time!

but if the .json file is in the same folder as the index file, when we move a file (suppose the list is arragned by name), then we can move the index file and the .json file together easily!

e.g.

file1.jpg
file1.jpg.json

it's very easy to use ctrl to select both file and move to other place together.

but now,
file1.jpg
.ts/file1.jpg.json

I have to do much more to move both files to the same place, and may need to make a new .ts folder!

so PLEASE make the .json file in same folder as the index file.

the .ts folder could be reserved for what thumbnails etc.
