Re: Is it possible to unset a mime type?

I solved the problem by editing the file /usr/share/mime/packages/freedesktop.org.xml . and then deleted the line
<glob pattern="*.crdownload"/>
then ran command

Code: Select all

sudo update-mime-database /usr/share/mime
Now the file type is detected correctly by its magic number in a file manager.

Re: Is it possible to unset a mime type?

I know how to use wget. But some download requires cookies, so if I copy the link and try to download in wget, the download does not start.
Hence, I must have to download in chromium.

Re: Is it possible to unset a mime type?

I can not use wget or some other download managers, because some downloads can not be started separately in a download manager. May be the site requires cookies or something else to start download.
