 |
|
ok so on to the next problem..
i want to compair the contents of some files so there is no dups,
the file names may be different but the contents are the same
so is there a dll(freeware) that might compair whole files or must it be done some other way?
perhaps do a filesize and then compair the sizes and then take a line
and and compair?
thanks for any input |

You could do a MD5 hash of each file and compare that.
http://www.fourmilab.ch/md5/
| Code: | # Create MD5 file
directory change,%%Path
runh @chr(34)@path(%0)md5.exe@chr(34) @chr(34)%%FileName.%%FileExt@chr(34) ,pipe
if @ok()
%p = @pipe()
end
if @not(@null(%p))
binfile open,1,%%Path\%%FileName.md5,create
binfile write,1,text,%p@cr()@lf()
binfile close,1
%p = ""
end

here's what i hacked up, works so far
(vds4)
| Code: | EXTERNAL string.DLL
list create,1
list create,2
list create,3,sorted
list filelist,3,c:\windows\desktop\alerts\*.txt,
list seek,3,0
rem the file you are going to put in dir
rem check to see if there's a match
%%file1 = c:\windows\desktop\alerts\ALERT10.17.07--1.51.58pm.txt
list loadfile,1,%%file1
%%listcount = @count(3)
repeat
%%listcount = @pred(%%listcount)
%%file2 = @next(3)
rem info 1 %%file1 %%file2
list loadfile,2,%%file2
if @null(@string(Equal,@text(1),@text(2)))
info nope no match
else
info they match @cr()%%file1 @cr()%%file2
if @query(delete?)
file delete,%%file2,
end
end
until @equal(%%listcount,1)
list close,1
list close,2
list close,3 |
