View status while comparison in progress

[vbn]

I use FFS for comparing huge directories with thousands of files and hundreds of gigabytes. Therefore, the comparison lasts for several hours.

In order to know in advance if it is worth waiting till the end, I would like to see the status while the comparison is still running. I would like to see some continuously updated statistics like:

Found:
- identical files: 1234
- left file is missing: 12
- right file is missing: 23
- file sizes are different: 34
- binary content is different: 45

Could you add this feature, please?

Just out of interest:
What would be the benefit of having such ongoing statistics ?
I don't see how one would see the benefit of waiting until the end or not.

Something I've not gotten around yet to posting regarding the CHK Hash Tool & while the circumstances may not be the same, the idea that if some information is presented, ahead of time, may influence you to continue or to abort an operation depending on what intermediary results have returned, or (as in below) it would have allowed me to take actions on particular sets of files (even without having all results returned at any particular point in time).

CHK

would it make sense to display intermediary results ?

as it is, & drag 10 files into check, 5 pairs that i do expect pairs of duplicates
files are fairly large, so hashes are fairly time consuming
as it is, i have to wait for 10%..20%..30.. ... (100%) before any results are displayed


if intermediary results were displayed
after 20%, 40%, 60%, 80%
i would know, at those points, whether or not i've got dupes for those particular pairs

(instead of having to wait till all 10 files hashed, to find out)
[which they did]


& that is with 10.
but say i had, oh lets say, 402 pairs that i need to go through
(& it could be even more then that)

that will take some time
if intermediary results were displayed
i could act upon pairs while others are still computing...

+1 - What example could you give that would cause you to stop it?

Examples for using running statistics:

- If I can see that the number of mismatching files grows at the same rate as the number of investigated files (ie. they are all different) then I may figure out I selected wrong directories to compare.

- If I can see there has been 10 errors out of 10k compared ones and a millon files are still to go then I may want to stop the comparision becuase I expected no difference at all.
