how can I empty all the files in a fold by C++/C ??
software will running on unix like system.

u can look up the apis find how to view all the files in the folder ,and do what u want!

Traverse the whole fold recursively, delete all each file and create a new empty one with the same name.
I think that will be OK.

[djwinter]

the thing is I have absolutely no idea how to use standard C++/C to complile this. can you give me a example to delete "c:/temp", and recreate it?

[OpenHero]

你查找一下系统如何处理文件系统的API
遍历文件,删除文件,创建文件,文件操作是系统相关的操作

[jiaowenhao]

编一个递归函数，遍历本目录下的所有文件包括文件夹，在遍历的同时检测，如果是文件就删除

[djwinter]

so is that mean the onlyway can use is the system command? there is no way to complile the dir operation regardless the os?

[OpenHero]

maybe 现在是没有找到c/C++自己封装的文件系统的API

there is only config file in this fold, what I nead to do, is before recreate all the file, empty all the file first, avod the unexpected system error.
and can you let me know a little more detail about it?

that what I am trying to do, have not find a proper way to do this, I think c++ STL should offer this simple dir operation for us, but .......................
wish anyone may face this before and can help.
