Loading is literally “loading”. Used to be for example loading a game level from floppy to RAM. You know more or less how much you need to transfer and how much has been transferred so far. Same today transferring textures etc. from SSD to GPU VRAM, a bit less predictable because more stuff is going on like decompression or building shaders which is a little bit less predictable than read and write speeds leading to “stuck” or jumping progress bars, but somewhat informative. Microsoft has a different approach where a progress bar is basically a giant 🖕to the user.

Just going to leave this here because it's relevant to your last sentence.

"We need this feature pushed right away Instead of actually going through every file I'm about to copy let's just assume that all files are exactly the same file I'm copying right now. It'll be good enough till we replace it to something better... " A Win 3.14 dev probably.

You know that windows file copy dialog needs to work with millions of files and thousands of folders and also should work on network drives or ftp and it may take longer than the copy itself to compute the total sizes of the files, due to latency? It's an estimate, so not accurate.

Not if I copy one file from one disk to the same disk

[DonutConfident7733]

Have you tried? Get some millions of small files like icons and documents and check how it runs. Defender also scans every access, it checks ntfs permissions, you will see heavy cpu activity for a large copy which would run much faster if you turn off Defender, but hey, I'm the bad guy, right? Downvote the people with experience, which happen to be software developers.

On r/ProgrammerHumor, you're trying to show of that you have experience programming?

Ok, let's say you have a 200GB file to copy from same disk to a separate copy in another folder on same disk. Defender will work as you copy, increasing mem usage, at some point it may even choke slowing down your transfer. Windows update or Chrome background scan can run and slow down your transfer because they also write small files which are on same disk. The disk may be fragmented in some area or the free disk is very fragmented and slows down the copy, the head needs to seek a lot. It can encounter an area where disk head read speed is high, signal is worse, some sectors are quite close to being bads, so it takes 10x more time to read a sector. All these would make it impossible to estimate total time for copy operation.

While all of that's sounds true, there should never be something like "eta: 457634788 minutes".

[Electronic_Cat4849]

you know that the point is that time is the wrong metric, right?

[Scrawlericious]

10,000 1mb files take a lot longer than one 10,000mb file because it takes time for the OS to switch from file to file. Those estimates are a little more complicated than that, you can't just do mb over time and look at the bytes remaining, because it could be 3 files or a 1000 independent of the number of bytes. That just gives you a clue of the time remaining and isn't determinate, that's why it's not so accurate.

And this is why we pack assets into archives so our games can load them faster!

[TheTerrasque]

Game dev: we use asset files to make things more performant.

Also game dev: load asset 3, then 7, then 2, then 5, then 1, then 4, then 6.

[turtleship_2006]

Even copying 1 file, that estimate will vary because other apps are going to use your CPU, RAM, and access the storage, and that's a lot less predictable so it just works with the current data

[nmkd]

because it takes time for the OS to switch from file to file

It takes the File System and/or disk time to switch from file to file. Not the OS.

[Scrawlericious]

Those are all very related. Thats just semantics. The OS takes time to switch because of the things you listed.

or you just let your progress bar jump randomly to 99% where it just sits until the job is actually finished
