How to change "input file" storage location in customer account edit form

Question

I have added a customer attribute called "My File". It gets added in customer account edit form. By default, the selected file(My File) is saved under "pub/media/customer" directory. In my case, I want to save those files alone under "pub/media/my_files". How to achieve it? Please help me!

You can modiy code as per you need. I suggest you to observe customer_register_success event. More about observers here.

        $uploaderFactory = $this->uploaderFactory->create(['fileId' => 'my_file']);
        //Magento\MediaStorage\Model\File\UploaderFactory
        $uploaderFactory->setAllowedExtensions(['jpg', 'jpeg', 'png', 'pdf']);
        $imageAdapter = $this->adapterFactory->create();
        // Magento\Framework\Image\AdapterFactory
        $uploaderFactory->setAllowRenameFiles(true);
        $uploaderFactory->setFilesDispersion(true);
        $mediaDirectory = $this->filesystem->getDirectoryRead(DirectoryList::MEDIA);
        $destinationPath = $mediaDirectory->getAbsolutePath('your preferable directory under media');
        $result = $uploaderFactory->save($destinationPath);

        $document = $result['file'];
