File Type Block

Server

Hello, I have a question. Can we block users from uploading certain file types? For example iso

Yes, you can do that with the file firewall which is part of the enterprise edition.

Thank you for your answer. Is there an alternative for Community Edition?

Actually in ownCloud Infinite Scale you can do it, I had ownCloud 10 in mind only when answering. Its a post-processing check you can setup.

Well, I knew I saw such an option somewhere. Even if I never tried it, it sounds promising.
From the file config/config.sample.php:

/**
 * Define blacklisted files
 * Blacklist a specific file or files and disallow the upload of files
 * with this name. `.htaccess` is blocked by default.
 *
 * WARNING: USE THIS ONLY IF YOU KNOW WHAT YOU ARE DOING.
 */
'blacklisted_files' => [
        '.htaccess'
  ],

/**
 * Define blacklisted files regular expression(s)
 * Blacklist files that match any of the given regular expressions and disallow
 * the upload of those files. The matching is case-insensitive.
 *
 * WARNING: USE THIS ONLY IF YOU KNOW WHAT YOU ARE DOING.
 */
'blacklisted_files_regex' => [
        '.*\.ext',
        '^somefilename.*'
  ],

If you use a valid regex, it will work. The file will then be refused.
Unfortunately, the blacklist-check will be performed AFTER the upload of the file, what I consider as nonsense.
