Standardized file names provide many conveniences for effective document management.When managing documents in practice,we often encounter a large number of non-standard file names.Changing the file name manually not only consumes a lot of time,but also is prone to errors.By using regular expressions to extract information such as date,title,and department from the file name,and then recombining the file name with this information,the file name can be standardized in batches,achieving the goal of quickly and effectively managing documents.
