当我将文件从相机复制到计算机时,文件扩展名为大写。我找到了这个question and answer,但建议的解决方案不起作用。
我的问题是为什么建议的解决方案不起作用,如何重新命名文件,以便我只通过使扩展名小写来修改文件名?
注意:文件存储在NAS(Synology DS1813 +)上。
这是我尝试重命名文件:

答案 0 :(得分:0)
一位朋友指着我this。链接的文章长达8页,但在解释中却很冗长。答案的简短版本是:
... And that brings me to what I really want to discuss, which is how
CIFS Server (Samba) deals with this.
As you would expect from an application that was grown to bridge
the gap between the Unix and Windows worlds, it is very flexible.
This is both good and bad - with flexibility comes responsibility,
and sometimes not a little confusion. There are four configuration
options that Samba provides to allow one to define its behavior
when dealing with matters of 'case':
preserve case = (yes/no)
short preserve case = (yes/no)
default case = (upper/lower)
case sensitive = (yes/no)
解决方案是configure Samba以处理案件敏感性(或案件保存问题)的方式,以满足您的特定需求。
