Can I remove those .backup and .../script.bak/... files from my directory?

Hi,

I have over 2200 file with the following structure:

/administrator/components/com_easyblog/controllers/blogs.php.backup
/media/com_easyblog/resources/default-3.9.19335.js.backup
/media/com_easysocial/apps/user/blog/blog.php.backup
/components/com_easyblog/themes/vintage/blog.read.php.backup

and

/media/com_easysocial/scripts.bak/site/dashboard/feeds.json
/media/com_easysocial/scripts.bak/apps/fields/user/permalink/sample_content.js
/media/com_easysocial/scripts.bak/story/friends.js
/media/com_easysocial/scripts.bak/site/dashboard/groups.js
etc...

Can I remove them safely?

Thanks
