Hi:

I have an unmanaged windows C++ app that's using the boost libraries.

What from the boost filesystem do I use to delete all file's from directory?
I create a Path based on a string path:

Path("c:\\SomePath");

At that point I'm not sure how to delete all the files that reside in that directory.
How do I do this?

Thanks,
JohnB

You can do that using the native Windows API, boost isn't required for that. E.g.

SHFILEOPSTRUCT sfo;

ZeroMemory(&sfo,sizeof(sfo));

sfo.wFunc = FO_DELETE;
sfo.pFrom = FilePath;
sfo.fFlags = FOF_NOCONFIRMATION | FOF_SILENT | FOF_NOERRORUI;

SHFileOperation(&sfo);

Open in new window


to delete a subtree in the file system.

BTW, if you want to do that with Boos, try 'remove_all()' (http://www.boost.org/doc/libs/1_48_0/libs/filesystem/v3/doc/reference.html#remove_all), e.g.

boost::filesystem::path p = "c:\\SomePath";

boost::filesystem::remove_all(p);

Open in new window
