Windows all version-implements the specified path share

Calling the API function Netshareadd () sets the folder to share, and if you do not make other settings after calling this function, the network user cannot access the shared folder because it is in an NTFS partition and is under the NTFS file system access control, so it requires a 2nd step;
Call DOS command cacls, give guest user group read and write permission;
If you want to cancel the file share, call the API function directly Netsharedel ()

For folders in the FAT32 partition, the cacls command is not working, and this command is dedicated to files and folders in NTFS format. This means that the first step of this workaround is not available, so you can now only add file shares using the Netshareadd () function. After calling this function, if you do not make other settings, network users can access the shared folder but have Full control (this is the default sharing permission setting), and in the actual project we want to be able to programmatically control read and write permissions. In the NTFS partition, we also have the NTFS file system access control function hood, in the FAT32 partition can only rely on the operating system folder share its own permissions settings function.
