1) I really like this app, thank you!
I will definitely needed it:
Till now I had to manage the mass binary comparison elsehow.
Time to time I really check for identical files,
analysing their content.

2) sub result
However, such analysis can take huge time:
Imagine my HDD of 200 GB of data...

What I would need is the sub result,
the result of the firts step as described on

> Description of the Duplicate Files Finder Algorithm
> First, all files are sorted by their size, because files can be only equal, if they have the same size (logically).
> Then the files are compared with each other...

Well, only I need sometimes is the list of the groups (described by the size only)
and the files of that size (+ full path)
...even a textual exported txt would be enough.

Why is it enough?
There are many files I can say immediately that these are not same, or does not matter.
in that huge amount of data I expect cca 4000 groups,
and only cca 50 I expect to be resolved, as really important.
Such analysis I actually performed in a few seconds,
with this recent tool...

From the UI perspective,
a check box y/n "continue with binary analysis" would be enough, wdn't be?

Please, enhance the app that way,
please, give me the sub result.

Thank tou!
