Originally assigned to: @Yuvi9587 on GitHub.

I've already mentioned this issue in the previous one, but I've encountered it in new version too. Right now I am using version 5.6.0 and these are the part files that ended up in the folder for donburik:

And here's the log chunk for one of these files (t2_0cd65e9c):

⬇️ Downloading (Single Stream): 't2.png' (Size: 2.72 MB if known) [Base Name: 't2.png']
     Applied numeric suffix in 'Donburik': 't1b_7.png' (was 't1b.png')
✅ Saved: 't1b_7.png' (from 't1b.png', 2.26 MB) in 'Donburik'
   Post 64552635 Summary: Downloaded=2, Skipped Files=1
   Applying creator download specific folder ignore words (57 words).

--- Processing Post 63979429 ('Stocking NSFW...') (Thread: PostWorker__4) ---
   -> Skip Duplicate Original Name (within post 63979429): 't2.png' already processed/listed for this post.
   Identified 1 unique original file(s) for potential download from post 63979429.
⬇️ Downloading (Single Stream): 't1.png' (Size: 2.71 MB if known) [Base Name: 't1.png']
     Applied numeric suffix in 'Donburik': 't2_191.png' (was 't2.png')
     Applied numeric suffix in 'Donburik': 't2_191.png' (was 't2.png')
✅ Saved: 't2_191.png' (from 't2.png', 2.72 MB) in 'Donburik'
->>Save Fail for 't2_191.png': [WinError 183] Невозможно создать файл, так как он уже существует: 'E:\\Donburik\\t2_0cd65e9c.png.part' -> 'E:\\Donburik\\t2_191.png'

WinError text translates to "Can't create file, because it already exists".

I added a function that always checks the file name after the download is finished, and if it finds a .part extension or any other file name issue, it fixes it; I tested it and it worked, but I’ll check again and for now just remove the .part from the file—regarding the error "Save Fail for 't2_191.png': [WinError 183] Невозможно создать файл, так как он уже существует: 'E:\Donburik\t2_0cd65e9c.png.part' -> 'E:\Donburik\t2_191.png', does this mean t2_191.png already exists, and is the error related to a unique file you want to download?"

Yes, t2_191.png already exists. This artist had all of post images named t1, t2, etc., which is why the suffix became like this. I have a guess that maybe because there were several files named t2.png downloading at the same time, it tried adding same suffix to both of them, but only saved one - the other just resulted WinError and file remained with its original name.

If they are unique and being skipped, you can use the manga/comic mode to rename them to either their "Post ID" or "Date + Title" for now.

Do I need to have anything else checked to allow checking "Manga/Comic Mode"? It doesn't allow me to check it.

You need to have a creator link or a creator selected to use it. It doesn't work for single post downloads.
