用dos批处理实现建立文件夹（Building folders with DOS batch processing）
Requirements: 1 requires the establishment of file names in the form of YYYY1-MM1-DD1 to YYYY2-MM2-DD2 folder
2, where YYYY1-MM1-DD1 is todays date; YYYY2-MM2-DD2 is four days later
Answer:
@echo off
REM comparison operator: EQU - equal to NEQ - not equal to LSS - less than LEQ - less than or equal to GTR - greater than GEQ - greater than or equal to
REM modulo operator: operator from DOS% (batch file in%, non batch command line%)
REM log folder name initial value
Set filelog=%date:~0,10% to
REM variables for subsequent dates
Set /A y=0
Set /A m=0
Set /A d=0
REM takes the DD two in the date YYYYMMDD
Set /A dd=%date:~8,2%
Set, /A, ddp4=,%dd% + 4
REM takes the MM two in the date YYYYMMDD
Set /A mm=%date:~5,2%
Set, /A, mmp1=,%mm% + 1
REM takes the YYYY four in the date YYYYMMDD
Set /A yyyy=%date:~0,4%
Set, /A, yyyyp1=,%yyyy% + 1
Set /A yymd=yyyy, 4
Rem, if its 31 months (1,3,5,7,8,10,12)
REM special December
