Comparison Error #2327

Closed 1John419 closed 1 month ago

1John419 commented 1 month ago

Version 2.16.40.0 Windows 10 Pro 64-bit

Encountered a comparison error. Files are reported as Identical:

wm01

They are, in fact, slightly different:

wm02

I have repeatedly hit Refresh and tried close/open WM. Same results.

Update:

Options > Compare > Folder > Compare method

Size (default) ->> error

All other options ->> correctly report 'Files are different'

As a quick workaround, I switched to Quick Contents...

As you may have noticed, the Size compare method only compares file sizes, so if the file sizes match, the files is considered Identical. The Modified Date and Size compare method compares not only the file size but also the modification date and time of the file.

OK, appears Options > Compare > Folder actually means Compare Folder/File. Thanks for clarifying.
