Editor to share with you how windows to achieve the batch operation of deleting files, I hope you will gain something after reading this article, let's discuss it together!

1. Delete the 7-day extension bkf file under the current directory with a batch file (based on the current system time)

Example: forfiles / m * .bkf / d-7 / c "cmd / c del @ file / f"

2. Forfiles automatically deletes files 7 days ago (based on current system time)

Example: forfiles / p "d:/test" / s / m *. * / d-7 / c "cmd / c del @ path"

Change d:/test to the directory path you want; / d-7 means to delete files 7 days ago.

3. Delete all empty directories (take deleting the d:/test directory as an example):

Dir / ad/b/s d:/test/ | sort / r > d:/kill.txt

For / f "tokens=*" I in (d:/kill.txt) DO rd "I"

Del d:/kill.txt

4. Delete the files 7 days ago, and then delete all empty directories; copy the following to the bat file.

@ echo off

Forfiles / p "d:/test" / s / m *. * / d-7 / c "cmd / c del @ path"

Dir / ad/b/s d:/test/ | sort / r > d:/kill.txt

For / f "tokens=*" I in (d:/kill.txt) DO rd "I"

Del d:/kill.txt

5. Usage and parameters of forfiles command:

Forfiles / p / d / c

/ p specifies the directory in which to look for files, and the default is the current working directory.

/ d specify a date or number of days to compare whether the last modified date of the file meets the criteria.

/ c the command executed for each file found.

Example 1. To copy files in the C root directory with a last modification date greater than or equal to January 7, 2010 to the D root directory:

Forfiles / p "forfiles /" / d "2007-7-1" / c "cmd / c copy @ path DVR /"

Example 2. Delete the files under the backup directory of disk C that were last modified 10 days ago:

Forfiles / p "c:/backup" / d-10 / c "cmd / c echo deleting @ file... & & del / f @ path"

6. Forfiles / p contains the full path of the file to be deleted (e.g. F:/Logfiles) / m * .log-d-7 / c "cmd / c del / f

@ path "

Explain the relevant parameters and commands

/ p: specify the location where to start the search for files, or the current directory by default if not specified.

/ m: the wildcard characters used in file lookup, such as "* .log" in the code, are all log files, of course, you can also specify

All log files starting with manmee, such as "manmee_*.log". If you do not specify this parameter, it defaults to "*. *".

/ d [{+ | -}] [{|}]: specify the last modification time of the file you want to select. "/ d-7" is used above to indicate all

Days-based, 7-day-old files. Of course, you can also specify a specific time here, for example: "/ d-01swap 7Universe 2010" so that all earlier than 2010

The document of January 7th. Note that the specified time must be in the format "MM/DD/YYYY".

/ c execute the specified command on all files in double quotation marks ("). The default is" cmd / c echo @ file ". Used above

To "cmd / c del / f @ path" to delete the specified file. (@ file and @ path here are variables, which are explained below. )

Let's talk about the parameters used above:

PATH: represents the full path to the file.

File: indicates the name of the file.
