There is a document a.txt with content and format as follows:
This is actually a list, with dates at the front and file names at the back
....
2005-12-02 43324
2005-12-03 232323
2005-12-04 rjjjdj
2005-12-05 fhsh
2005-12-06 sdhsh

Purpose: Use batch processing to extract the file names in a.txt and delete the files created within a specified period of time. I want to delete the files created from December 3, 2006 to December 15, 2006. Is there a good method?

The following is the demonstration code. Replace the echo statement with the del statement when you are satisfied:
@echo off for /f "tokens=1*" %%i in (a.txt) do ( if %%i geq 2005-12-03 if %%i leq 2005-12-15 if not "%%j"=="" echo "%%j" ) pause

Another alternative method to delete files between December 3, 2006 and December 15, 2006: )

(Note: The following command deletes files from December 3, 2006 to December 15, 2006 inclusive


rar a /R /M0 /DF /TA20061203 /TB20061216 compressed_file_name the directory where the batch of files with the specified date is located

Using the characteristics of the WinRAR compression tool, after execution, the deleted file is equivalent to being moved into the compressed package. If you don't want it anymore, just delete the compressed package.RAR. If you mistakenly delete it, you can also extract and recover it.

The above instruction has been tested and passed. The following gives the parameter explanation of WinRAR. RAR.EXE /? has more detailed help: )

(Note: I directly copied the rar.exe in the WinRAR compression tool directory to the windows directory for convenient calling, and I'm too lazy to modify the environment PATH information: )

ta<date> Process files modified after the <date> described in YYYYMMDDHHMMSS format tb<date> Process files modified before the <date> described in YYYYMMDDHHMMSS format 　　　　　　　(Note: Refers to files before this date, not including the specified date of the day, so the date should be added by 1) m<0..5> Set compression level (0-storage...3-default...5-max) 　　　　　　　(Note: Use /M0 parameter, because the compression process is the deletion process, /M0 is no compression but only storage, so the speed is fast) df Delete files after generating the compressed archive 　　　　　(Note: That is, after compression, the source file is directly deleted, which plays the role of indirectly deleting unnecessary files in the directory) r Include all subdirectories 　　　　　(Note: The /R parameter is to compress the files in all directories under the specified directory) ……

Learned, so it can be like this. Thanks for sharing

Well, it can also be achieved with winrar~ Learned it
