Code:
foundc=0
nfoundc=0
fflist=""
nflist=""

for file in $FILELIST
do
   if [[ -s "${file}" ]];then
       # file is found and is > 0 bytes.
       foundc=$(( found + 1 ))
       fflist="${fflist}\n${file}"
       ...do something else you want...
   else
       # file is not found or is 0 bytes
       nfoundc=$(( nfounc + 1 ))
       nflist="${nflist}\n${file}"
       ...do something else you want...
   fi
done

print "List of found files:\n\n${fflist}\n---------"
print "List of NOT found files:\n\n${nflist}\n-----"

print "number of files in [$FILELIST] found = [${foundc}]\n"
print "number of files in [$FILELIST] NOT found = [${nfoundc}]\n"

I've not tested above so maybe couple of bugs.

You could of course save the outputs to a file instead of a variable.

NOTE: accessing the variable list of files will contain \n whereas printing it out should put each entry on new line.
