The description of the Size function is: # Returns the size of the external file represented by Name. The size of an # external file is the number of stream elements contained in the file. If the # external file is not an ordinary file, the result is implementation- defined. and a directory is certainly not an ordinary file. So if you give it a directory name as the Name, it could raise an exception (possibly Name_Error, but not necessarily), or it could return a result that means something implementation-defined, or it could return meaningless garbage. -- Adam ^ permalink raw reply [flat|nested] 6+ messages in thread

Oops! you are right. It raised Name_Error when I tested it. It would be nice if it returns some number such as 512 when issuing command line ls -l on Linux.

Both answers are do to the File System and Operating System designers. Most File System do not keep a running values of the number of files or the total byte size used in a directory. Even the Command "Dir" must calculate its values. So, you have to build an algorithm. PseudoCode like algorithm: -- The following algorithm counts all sub-directories as files -- with a size of 0. -- Also the directory entries "." and ".." are counted as 2 files -- with a file size of 0. Dir_Name := "dirname" ; -- dirname is the dir you want to process -- Files that have hidden or system attributes may or -- may not be counted and in some systems you may -- need to use Dir_Name & "\*.*" or Dir_Name & "/*.*" Dir_File := Open ( Dir_Name ) ; -- Total number of files File_Count := 0 ; -- In some file system an empty dir may use some -- bytes like 10 for root. So an offset nay be -- needed. Dir_Size := 0 ; while not end_of_file ( Dir_File ) loop Get ( Dir_File, File_Name ) ; File_Count := File_Count + 1 Dir_Size := Dir_Size + Size ( File_Name ) ; end loop ; Close ( Dir_File ) ; -- display the results Put ( "Directory: " ) ; Put ( Dir_Name ) ; Put ( " contains: " ) ; Put ( File_Count ) ; Put ( " files using " ) ; Put ( Dir_Size ) ; Put ( " bytes" ) ; New_Line ; In <13gbgls2c6q198b@corp.supernews.com>, "ME" <abcdefg@nonodock.net> writes: >I am looking for the number of files in a directory.
