But *(data[i]) is a structure and you need:
data=*(data[i]).(0)

Why not use a pointer array instead?
files = file_search('search string', count = ct)
data = ptrarr(ct)
for i = 0, ct - 1 do begin
x = ...code to read your file into an array...
data[i] = ptr_new(x)
endfor
then, you access each file's array by *(data[i])
