A batch file is a text file which contains a series of commands executed by a command interpreter for Microsoft's Windows operating system. It batches a set of commands into a single file with a .bat filename extension.
Windows versions of operating systems run from DOS and use the same command interpreter to execute batch files. You can use date and time DOS commands to generate timestamps in batch files. You can also schedule the batch files to run at a particular time and automate series of commands. You can use the DIR command which allows you to see the available files and subdirectories in the directory.
Create a Batch File with Filenames and Timestamps
Here is a batch file that will display all files, subfolders and subfolder files with both date created and date modified timestamps. The resulting file may be saved as either a .txt or .xls file.

/B - Uses bare format (no heading information or summary).
/C - Display the thousand separator in file sizes. This is the

/D - Same as wide but files are list sorted by column.

/O - List by files in sorted order.
sortorder N By name (alphabetic) S By size (smallest first)

displayed in its place.
/4 - Displays four-digit years
Switches may be preset in the DIRCMD environment variable. Override
preset switches by prefixing any switch with - (hyphen) — for example, /-W.
