This command will search for all file type with a case insensitive ending of .conf.
find . -type f -iname "*.conf"
This will do the same search however only in the current directory, means it will not recurse through the directory.
find . -maxdepth 1 -type f -iname "*.conf"
This search will search for all file over 50 Kilobytes. If we replace k with M we get megabytes I suppose (Would it kill you to look up the man page yourself ?).
find . -maxdepth 1 -type f -iname "*.conf" -size +50k
find . -type f -iname "*.conf"
