  Compare Files

 Here's a little function that will compare if two files are the same at binary level.  All you need to do is supply it with the absolute locations of both files and it'll brute force the comparison.    It works by loading the entire contents of both files into a pair and strings and then doing an equality test (=)  upon them..

PlayBASIC Code: [Select]

   path$="C:\Location Of The Files You Want to Compare\"

   file1$  =path$+"filename1.txt"
   file2$ =path$+"filename1.txt"

   result=CompareFiles(File1$,File2$)

   print Result
   Sync
   waitkey

   

function CompareFiles(file1$,File2$)
   Result=false
   if lower$(File1$)=Lower$(file2$) then exitfunction true
   if FIleexist(file1$) and FIleexist(file2$)

      size1=filesize(file1$)
      size2=filesize(file2$)
      if Size1=Size2

         // load file 1 intoi a string
         f1=readnewfile(file1$)
            FileString1$=readchr$(f1,size1)
         closefile f1

         f2=readnewfile(file2$)
            FileString2$=readchr$(f2,size2)
         closefile f2

         // compare them 
         result=FileString1$=FileString2$

      endif
   endif
EndFunction Result
