Set Folder and Files in folder to compress attrib

Hello,

is there a way to set a folder (and all files with folders)
to compress attrib? I find in the help only other attribs.

What is when the installer set compress in Win9X?

compression is NTFS only, there is probably some api you can call with the system plugin

FILE_ATTRIBUTE_COMPRESSED attribute cannot be set with SetFileAttributes() instead msnd suggest using DeviceIoControl() api with FSCTL_SET_COMPRESSION operation.

FSCTL_SET_COMPRESSION - Win32 apps

Sets the compression state of a file or directory on a volume whose file system supports per-file and per-directory compression.
