If the word document is not saved after accidentally closing, it can be recovered by the following methods:
Check the file recovery function: First, reopen the Word software, on the welcome screen or under the [File] tab, check the [Recent Documents], find the recently opened document, and try to recover.
Check the auto-recovery feature: If you don't have the required documents in your recent documents, you can try to use Word's auto-recovery feature. After reopening the Word software, the software automatically activates the Document Recovery task window to list the unsaved documents. Select the files you want to recover and click [Recover].
Check File History: If the above methods fail to recover documents, you can check File History. In Windows systems, the File History feature can automatically back up files and allow users to restore files. Under the File tab, select File History, and then follow the prompts to restore.
It is important to note that if the document is not saved before closing or the save is not successful, then the possibility of recovery is limited. Therefore, it is recommended to save the document in time when editing it to avoid the risk of data loss.
The above methods are for reference only, if you cannot recover the files, it is recommended to seek professional technical support for help.
