#128 Problems comparing DVD content vs hard disk

Takashi Sawanaka — Sat, 14 Mar 2026 06:28:41 -0000

My DVD drive is currently broken, so I cannot reproduce this issue at the moment. However, similar reports have been made in the past and we still do not know a definite solution. It seems likely that this behavior is caused by Windows rather than WinMerge itself.

Problems comparing DVD content vs hard disk

John Richards — Fri, 13 Mar 2026 18:34:53 -0000

I am trying to compare a DVD drive content "S:" with files on the hard drive. When I browse to say "S:\Files\" it instead changes to
"C:\Users\John\AppData\Local\Microsoft\Windows\Burn\Burn\Files1\" and cannot find the files. I can then overtype to make it "S:\Files1\" but when I select the next folder it does this again and every time!!! Using current version 2.16.54.2 and also previosus version 2.16.52.2

Is there a fix for this?

Adding the /cfg ShowIdentical=0 option will work.

Hello I am trying to setup winmerge to not have identical files in the CSV report, so as to avoid copying files that are not needed, is this possible via command line?

Here is my current command

WinMergeU /r /m Binary -noninteractive /s "$LeftFolder" "$RightFolder" -noprefs /cfg ReportType=0 /cfg DirViewExpandSubdirs=1 -or $OutputFile /xq

Thanks,
Jim

Currently, there is no option in WinMerge to remove the top two lines from the report.

Just to make sure I understood the last comment, it is not possible to remove the top 2 lines from the report?

Unfortunately, it is currently not possible not to output a two line header.

ok one last question, is there a way to manipulate the report so it will not have the 2 line header on it? I would like it to have row 3 as row 1 so I can read from the csv in my script

You can output the results of the recursive folder comparison to a CSV file with the following command :

"C:\Program Files\WinMerge\WinMergeU.exe" /r /noninteractive /cfg ReportType=0 /cfg DirViewExpandSubdirs=1 path1 path2 -or c:\tmp\report.csv
