我找到了一个\*\d{2}可以满足我需求的地方，但是它却不行。
答案1
为了查找，-{digit}{digit}请使用正则表达式-\d\d（或-\d{2}）。
答案2
为了准确可靠地消除所有前缀并且只消除它们（没有其他内容），假设所有文件都有.flac扩展名，您可以使用：
\\\d{2}-(.*?\.flac)$
用。。。来代替：
\\$1
分解：
\\- 反斜杠\d{2}-- 后跟 2 位数字和-(.*?\.flac)- 并且.flac扩展名之前的任何非贪婪匹配项都被捕获到组号 1 中$- 行结束
然后我们用\\反斜杠和第一组（$1）替换。
答案3
- 找什么：
^.+\K\d{2}-(?!.+\d{2}) - 替换为：保留空白
- 搜索模式：
Regular expression - 使能够
Wrap around - 按Replace All
说明
^.+尽可能多次匹配一行开头的任意字符
\K忘记到目前为止匹配的所有内容
\d{2}-匹配 2 位数字后跟一个破折号
(?!.+\d{2})：负向前瞻。当前位置后面不能跟很多字符，后面不能跟 2 位数字和破折号
这允许仅删除文件名中破折号后的 2 位数字，而不是文件夹名称（参见第 13 行）。
