Bug in ignore whitespace ?

[remfan77]

Hello,
I do not understand how WinMerge ignore whitespace works.

I use the option ignore white space.

I have two folder A and B.
Each folder A and B contains 2 files,

1. FILE.txt
2. SPI.c

Ignoring whitespace folder A and B should be the same.

WINMERGE-BUG-WHITESPACE.zip

Why I see

But If I click on SPI.c WinMerge correctly tell me SPI.c are the same.

Can someone explain the reason ?
Is it a bug or I miss something ?

Best regards,
Paolo

You probably have the following settings

Whitespaces: Ignore change or Ignore all
Ignore blank lines: enabled
Compare method: Quick Contents

If you set Compare method to Full Contents, you will get the result you expected.

It's most likely a Quick Contents compare method bug.

Thanks for you quick response.

Do you mean Diff Algo (experimental) ?
In WinMerge 2.16.30 I have

• default
• min
• patience
• histogram
• none

Tried all, but I have always the same problem.

Compare method can be changed as follows.
