Combine comparison variants like "File content" AND "File size"

[Ballinho]

Hi,

I'm using FFS for a long time now for my backups.

In the past I had a problem that some of my pictures got corrupt, so that half of a pic is grey for example.
I had sometimes copies of those pictures. But even if they are different, they still have the same timestamp AND the same size. Only when I compare them via "File content" FFS shows me that they are different.

1. I would like to compare "File time", "File size" and "File content" at the same time, to delete one copy afterwards.
Is that possible?

2. I would like to get a list where "File time" AND "File size" is the same, but the "File content" is different to find my corrupt pictures where I have a good backup of. Is that possible?

So my request would be to combine the comparison-variants with AND and OR and brackets as I want to have it.
Like an easy sql ;-)

Thanks a lot.

Simply comparing by file content should find all corrupt files, doesn't it?
