When I want to seed a torrent with many files, but I don't have the whole source the qBittorrent create placeholder files and folder structure to replace the missing parts. These files are unusable and won't be downloaded. I guess this is happens for indexing purpose. But has two major disadvantages:

Massive HDD usage during the creating process.
It uses as many space on my HDD as the whole source for nothing.

There are massive CPU usage during the creating process and I can't stop/cancel the process unless I kill the process.

This doesn't make any sense. In uTorrent I was able to stand in the seed without creating placeholder files to replace the missing parts. For example season packs. If I only have the last season and the rest are not.

Is this bug or by design?

Have you disabled Tools->Options...->Downloads->preallocate disk space for all files?

No, this option is enabled. But I enabled this option in uTorrent too, because it reduces the file system fragmentation.

I thought "all files" means: all files what I've checked for download.
I disabled this setting and now only created an empty .unwanted folder in the unwanted directories.
