Hello Expert, in phpmaker, we know that if we upload files it store to htdocs/systemname/uploadfolder, do we have any other way to store files in drive D:?
No, you should not use absolute path, there may not be a D drive on your production server. You should use a relative path (relative to the project folder). If you want to upload outside the project folder, you may use the advanced setting Local file system root (relative to project folder) (e.g. "..") to set the root of the local file system, then set your upload folder paths relative to the root.
