I am following below Article to upload file in store configuration:
https://www.mageplaza.com/devdocs/how-file-upload-sytem-configuration-magento-2.html

I have defined custom backend model as mentioned in this artice to validate my file type:

<?php

namespace VendorPackageModelConfigBackend;

class CustomFileType extends MagentoConfigModelConfigBackendFile

 /**
 * @return string[]
 */
 public function getAllowedExtensions() 
 return ['csv'];
 

?>

and in system.xml, it's like this:

<field id="import" translate="label" type="MagentoConfigBlockSystemConfigFormFieldFile" sortOrder="1" showInDefault="1" showInWebsite="0" showInStore="0">
 <label>Import CSV</label>
 <comment>Comment</comment>
 <backend_model>VendorPackageModelConfigBackendCustomFileType</backend_model>
 <upload_dir>upload</upload_dir>
</field>

but it's not working. I can upload image files too!!

What's wrong with this code?

  Code looks fine. Did you run di:compile and flushed the cache as well?

I found answer by referring

vendormagentomodule-configModelConfigBackendFile.php

Correct Function name is _getAllowedExtensions not getAllowedExtensions

So, correct method is:

public function _getAllowedExtensions() 
 return ['csv'];
