Windows automatically deletes the batch script of files from n days ago

The database backs up files every day, but only needs to keep the backup for seven days. Write a batch script file to automatically delete the files from seven days ago and set up scheduled tasks.

Automatic deletion of files requires the forfiles command

Forfiles parameters:

/ p specified path

/ s includes subdirectories

File name mask for / m lookup

/ d specifies the date, with absolute and relative dates, where-7 refers to 7 days before the current date

The command line run by / c represents the commands executed for each file. The command string should be enclosed in double quotes.

The default command is "cmd / c echo @ file". The following variables can be used in the command string:

@ file-returns the file name.

@ fname-returns a file name without an extension.

@ ext-returns only the extension of the file.

Path-returns the full path to the file.

Relpath-returns the relative path to the file.

Isdir-returns "TRUE" if the file type is a directory, or "FALSE" if it is a file.

Fsize-returns the file size in bytes.

Fdate-returns the date the file was last modified.

Ftime-returns the time when the file was last modified.

Create a new notepad file, enter the following command, and name the file "Delete the file that was backed up 7 days ago. Bat". Note the path where the file is located.

@ echo off # requires the password forfiles / p "C:\ autoscpfile\ data" / s / m * .bak / d-7 / c "cmd / c del / f @ path" forfiles / p "C:\ autoscpfile\ log" / s / m * .txt / d-7 / c "cmd / c del / f @ path"
