Hello,

I want to make a scripts that can compare files in a directory (including subdir's). When two files are the same it has to write both file locations and file sizes into a log file.

Any idea how to handle this?

Please use the KiXtart BBS Search as these topics have been discussed numerous times.

Potential solution:
Enumerate files in first directory with any of the DIR UDFs that are posted in the UDF Forum.
Check whether an identical file exists in the second directory. Finally, if there's an identical file, wirte into log file with WRITELINE
code:
;pseudecode (non-working, for illustration purposes only)
$filelist=dirplus('c:\temp\*.*')
for each $file in $filelist
  $newfilelist=dirplus('d:\temp\'+$file)
  if $newfilelist
    ; write log file
  endif
next

Martijn,
You may want to better phrase your question. The way I interpret what you say, you want to compare each file in a given folder with every other file in the same folder as well as sub folders. If that is the case you have a lot of recursion to do.

You should probably elaborate.

Well i guess size is the most accurate one.
But a combination of size and name would be great.

Martijn,
That doesn't make sense. If you are going to compare files in the same dir then they obviously can't have the same name. Contrary topopular opinion, size doesn't matter either. Files can be the same size but different.

The only way to be sure is to use a full compare like FC.EXE or the like.

If I may Les,

I think he means he wants a script to look for DUPLICATE files and then write it to a log file. Example WIDGET.EXE may be in 5 or more different directories, and he wants to log all of them.

Not sure why he wants to use KiXtart to do it with though, as there are numerous programs out there that will already do that much quicker then KiXtart can. However, if he is wanting to do it as a LEARNING experience to better his skills at KiXtart... then hey what the heck. [Wink]

DOC,
That is why I asked for clarification.

Les,

Sorry for the wrong answer i gave you but what NTDOC said in his last post is what i really want to do.

I want to check if there are file more then ones in our department/home folders. Just to see how much diskspace there could be saved if people cleared their mess more often.

NTDOC,

wich programs are you talking about?

Martijn,

So are you looking to see:
  • File names
  • Quantity of files
  • Size of files
  • Differences
  • Similarities
??

Kent,

I want to see how many duplicate files there are and what sizes they have. So that i can make a report to how much drivespace is taken by useless data.

Probably the easiest way to address the duplicates is to write these folders out to a text file and run it through MS-Access "find duplicates wizard" in the query builder.

Under NT, you would do something like -

DIR E: /B /S > C:\DRVLOG.TXT

Then you could link or import this file..
