这是什么应该做的是从文件名和标题情况下，即文件
What this should do is remove certain characters from filenames and title case the files ie
some_filename = Some Filename
filename number 2 = Filename Number 2
它的大部分工作正常，如情况下更改和删除多余的空格和下划线
Most of it works fine such as case changing and removing extra spaces and underscores
但我有特殊字符，如麻烦！（10条线在code下）
如果一个文件名命名的文件，即！二是忽略
But i am having trouble with special characters such as ! (10 lines down in code)
if a filename is named ie file! 2 it is ignored
使用^！= ^！=，但无济于事。
推荐答案
您不能推迟展开如果变量包含时启用展开像%%变量！或 ^ 。延迟的扩张将破坏的价值，因为一个！被剥离，两个！将间$ P $磅的字符作为一个变量并展开它（可能是没有），而 ^ 将被剥夺，因为它是用来逃跑！。
You cannot have Delayed Expansion enabled when you expand a FOR variable like %%A if the variable contains ! or ^. Delayed expansion will corrupt the value because a single ! is stripped, two ! will interpret the chars in between as a variable and expand it (probably to nothing), and ^ will be stripped because it is used to escape !.
您最简单的方法是顶级改为 SETLOCAL DisableDelayedExpansion ，并替换为 CALL指令%% VAR %% 的技巧，你已经使用在其他地方。该CALL诀窍是不是推迟扩张慢得多，所以通常我会建议延迟切换扩张。但我认为这种切换可能会在你的情况变得复杂。
Your easiest solution is change the top to SETLOCAL DisableDelayedExpansion, and replace all delayed expansion with the CALL command %%VAR%% trick that you are already using elsewhere. The CALL trick is much slower than delayed expansion, so normally I would recommend toggling delayed expansion. But I think the toggling could get complicated in your case.
我也建议你改变：RmLoop定义
I also suggest you change your :RmLoop definition
:RmLoop
Call Set "_FileName2=%%_FileName: = %%"
If "%_FileName2%" neq "%_FileName%" (
set "_FileName=%_FileName2%"
goto :RmLoop
)
此外，我不明白为什么你本身你打电话后更换空间：RmLoop
Also I don't understand why you replace a space with itself after you call :RmLoop?
我不知道是什么 **！=** 替换正在尝试。也许这可以去掉？
I'm not sure what the **"!="** replacement is attempting. Perhaps that can be removed?
