Please provide the following information

qBittorrent version and Operating System

4.1.7, Windows 10

What is the problem

Create a torrent for a folder that is 168GB with over 111,617 files, 4,873 folders. Once torrent is create, add torrent manually to client and check data, torrent only 98.8% complete.

What is the expected behavior

Torrent is 100% as i just made it.

Steps to reproduce

Create torrent file from folder with 111,617 files, 4,873 folders and possibly really long folder and filenames(all working inside windows), add torrent file to client, check torrent file. torrent reports 95%

Extra info(if any)

I went to the folders where the supposed missing files are (pictures) and they do still exist and are not corrupt. I've done scandsk with no errors and the drive is not fragmented.

I've created and checked the torrent twice now and the same result. I'd have to take some screen shots and create it a third time to see if it is the same files and folders that are not being detected properly.

@madhatr
Possibly related qBittorrent issue: https://github.com/qbittorrent/qBittorrent/issues/10913
Possibly related libtorrent PR (opens up potential to fix this issue in qBittorrent, will be included in the upcoming libtorrent 1.2.2 release ): https://github.com/arvidn/libtorrent/pull/3877

@Chocobo1 can you please take a look at this as well as https://github.com/qbittorrent/qBittorrent/issues/10913? Not a huge priority, maybe wait until libtorrent 1.2.2 is released to ease testing a bit.

Seems have similar problem of torrent with large size(more than 100G).
The files of torrent was checked 100% in utorrent and deluge, but if check torrent with qb, qb reports 99% or 98%.

Superseded by https://github.com/qbittorrent/qBittorrent/issues/12029. See also https://github.com/qbittorrent/qBittorrent/issues/10913. The torrent loading parameter defaults have been raised since these issues were posted, but is possible that they are still not enough for some large torrents. To solve the general problem, the torrent loading parameters must be configurable, and that is tracked in https://github.com/qbittorrent/qBittorrent/issues/12029.
