Normally, novels that were accidentally deleted from the bookshelf could not be recovered. This was because the novel was a digital file that could not be recovered after being deleted. Even if you tried to use data recovery software, there was no guarantee that you could successfully recover the file. If the novel on the bookshelf is deleted by mistake, the following measures are recommended: 1. Try to avoid writing the same file again to avoid erasing the deleted file. If you are unable to recover the files by yourself, please seek the help of a professional data recovery service. However, please note that this service is usually expensive and cannot guarantee that the recovered files will be completely recovered. 3. If you decide to perform data recovery, please make sure to back up important data such as novel files, notes, etc. before the operation. Therefore, in order to avoid unnecessary data loss, it was recommended to handle the novel files on the bookshelf carefully and take timely measures to avoid re-writing after deleting them.
