It works for me but only to an extent. I thought the folder compare was showing them as different.. before, but then I clicked on them and it said same. I did a compare again and I see it shows them as = which is what you want. so it's certainly possible to show them as equal, which is the result you want. right? but thing is, it came after I double clicked the file.
notice the byte size is different, that is because one is \r\n and one is \n.
Initially I got a screen showing difference
in the sense that, the colors were different, and when I clicked "View..Show Same", the files that had different line endings but were otherwise the same, didn't show. Session..folder compare info also didn't say that ggg.a was the same in both folders.
The main screen showed them as the same once I double clicked one and viewed the two files in a new tab to view the files, then the previous tab I was in, if I recall, updated to show this. that ggg.a was the same (Despite the byte difference).
It's unfortunate I had to double click the file to do it, but BC can do it. You might find how to automate it more, or do it more efficiently with BC.
dangph's answer looks like it then. Session..session settings..comparison tab. My one was set to "rules-based" but that "compare contents" box has to be checked too. I see it says "requires opening files". I think once that "compare contents" -there- is checked then opening files is automatic. When doing Action..compare contents, it says crc, or binary or rules. I've chosen rules(not binary), but it only works for the pc/unix thing, when the "compare contents" box is also checked in session..session settings screen. Even though one is choosing "compare contents" when doing action..compare contents! And even though one is not choosing binary. That "compare contents" box has to be checked in session..session settings.
