NConvert as Explorer contextmenu

[PeterleB]

Hallo,

I want to use nconvert with parameters to convert webp to jpeg in windows explorer (old menu).

Code: Select all

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\SystemFileAssociations\.webp\Shell\convert]
@="Zu JPG konvertieren"

[HKEY_CLASSES_ROOT\SystemFileAssociations\.webp\Shell\convert\command]
@="\"C:\\Program Files\\XnView\\NConvert\\nconvert.exe\" \"-out jpeg %1\""

The command is: "C:\Program Files\XnView\NConvert\nconvert.exe" "-out jpeg %1"

Nothing happens and no errors are displayed. What am I doing wrong?

Hi,

I installed the executable and subfolders with plugins from xnview_full.zip new.
The new command is:
"C:\Program Files\XnView\nconvert.exe" "-out jpeg %1"

I see a brief command window but no new file is written.

Regards
Peter

Using NConvert in this way is well outside my experience, maybe Pierre can help? Or maybe Helmut or michel038??

If you haven't done so already, you might test using another input file format such as PNG, in case the issue is due to a missing WebP plug-in, for example.

Now you have NConvert opening, have you experimented with variations on the quotes in the terms "-out jpeg %1"? There are a number of possible variations including complete removal that you could test quickly, without thinking about the logic for using them!

could you try

Code: Select all

"C:\Program Files\XnView\nconvert.exe" -out jpeg "%1"

Your suggestion with the changed quotation marks was correct.
It works!
Many Thanks.
