ObjectPascal FileSearch Function Search for a file in one or more directories SysUtils unit

function FileSearch ( const FileName, DirectoryList : string ) : string;

Description The FileSearch function searches for the given FileName in the given DirectoryList.   The FileName may be a file name or sub-path to a file.   The DirectoryList is a ; separated list of directory (path) names.   If the file cannot be found, then an empty string is returned. Otherwise, the full path plus the name of the file is returned.   WARNING: the current directory (see GetCurrentDir) is ALWAYS searched first, regardless of the given directories. If the file is found there, then the returned path is Only the file name.   You have been warned! Notes If any of the specified directories do not exist, no error is thrown. The directory list can be an empty string - only the current directory will be searched.
