does anybody know how I would be able to take a file that is larger than a HD floppy (1.44mb) and split that file into parts that will fit onto more than one floppy? example : file.exe is 1.83mb The program looks at the file and splits it into file.01 which is 1.33mb and file.02 which is .50mb and a batch file file.bat. The batch file contains only the commands @echo off cls echo Splicing the files together @echo off copy /b file.01 + file.02 file.exe >nul cls How would I do the file size detection and split in Euphoria? Thanks, Philip Lettkeman phil.man at juno.com "Every man has his price. Mine just happens to be the love of my children."

If not, sorry for butting in. :)

You can determine the length of a file using the dir() function. Knowing the maximun bytes each split should have you can do something like this: -----< CODE START >----- -- SPLIT.EX -- Daniel Berstein 30/10/97 -- Usage: ex split <filename> -- Creates a batch file (join.bat) for recreating original file include file.e integer source, dest, splits object size atom max, offset sequence filename max = 1415577 -- About 1.35 MB -- Read filename filename = command_line() if length(filename) < 3 then puts(1, "Please supply a file to split.\n") abort(0) end if filename = filename[3] -- Get file size size = dir(filename) if atom(size) then puts(1,"Can't find file " & filename & ".\n") abort(0) end if size = size[1][D_SIZE] -- Check splits needed if size/max > 999 then puts(1, "Too many split files needed!\n") abort(0) end if -- Open source file source = open(filename, "rb") if source = -1 then puts(1, "Can't open file " & filename & "\n.") abort(0) end if splits = 1 offset = 1 -- Main loop while 1 do -- Create split file puts(1, "Creating split file #" & sprintf("%d", splits) & "\n") dest = open(filename[1..find('.', filename)] & sprintf("%d",splits),"wb") if dest = -1 then puts(1, "Can't create split file " & filename[1..find('.', filename)] & sprintf("%d",splits)) close(source) abort(0) end if -- Write split file while (offset <= max*splits) and (offset <= size) do puts(dest, getc(source)) offset = offset + 1 end while -- Close split file close(dest) -- Exit if all done if offset > size then close(source) exit end if -- Update splits file counter splits = splits + 1 end while -- Create batch file dest = open("join.bat","w") puts(dest, "@ echo off\n" & "cls\n" & "echo Recreating " & filename & "\n" & "@ echo off\n" & "copy /b ") for i = 1 to splits do puts(dest, filename[1..find('.', filename)] & sprintf("%d",i) & " ") if i <= splits - 1 then puts(dest, "+ ") end if end for puts(dest, filename & " > nul\n") close(dest) puts(1,sprintf("%d",splits) & " split files created and join.bat\n") -----< CODE END >----- Hope this helps you. i tested it on a 2.2 MB zip file and worked correctly (creating 2 splits).
