You may be able to recover the file by right clicking on it and select properties, go to Previous Version tab and if there is a previous version click on that. Also, it may be a temp file, look for files with .tmp and check modify dates to see if it may match when you lost the file.
Previous Version is a feature of File History that has to be turned on and it varies by version on how to set up. You can find information on setting up File History by searching for "Shadow copy windows" and then look for your version of Windows for information to set up.
It is also a good practice to save the file frequently, if you make structural changes (add columns, rows, tables and similar) you should save the file with something to show version such as fileV2. If fileV2 gets corrupted you can return to previous version to recreate the changes.
