Repporting duplicated files

[ivan]

Hi everyone!

I'm trying to clean duplicated files with different attributes, except size and extention. What I've done in the appended code is to :

1) get the user to input the file extention (this can easily be improved).

2) Autoit Runwaits Dir from command prompt and creates a list of files to compare (could also have used FileFindFirstFile).

3) Autit runwaits FC.Exe to binary compare the files.

4) If there´s a binary match then file path and name are appended to a text file. (this needs cleaning up as repetitions occur).

Watch out for line 82, you need to replace the spanish text FC.EXE returns if there´s a binary match for your OS language equivalent.

PROBLEM 2):

The script works fine for a small amount of dummy short txt files, but gets stuck with larger (i.e. pdf) files
