将绝对路径转换为批处理文件中的相对路径

Question

是否可以将绝对路径转换为批处理文件中的相对路径？ （与this相反）。显然你需要两个输入：转换的绝对路径，以及一个你希望它被相对化的绝对参考路径。

如：

Path to convert: c:\documents\mynicefiles\afile.txt 
Reference path: c:\documents 
Result:   mynicefiles\afile.txt 

Answer 1

@echo off 
setlocal EnableDelayedExpansion 
set Path_to_convert=c:\documents\mynicefiles\afile.txt 
set Reference_path=c:\documents 
set Result=!Path_to_convert:*%Reference_path%\=! 
echo Result: %Result% 

Answer 2

这里是工作，如果你想从一个字符串的开始删除％CD％的另一种方法。速度很慢，但如果情况允许，可以降低循环次数。
