Bug: Status Center shows 0 transfer speed when copying folder

[leafpmpmp]

Description

I was copying a folder from disk C: to D: , while it does show me the file being copied, transfer speed (MB/s) or item process speed (items/s) remains 0 during the entire process.

I tested this using 3 different folders, and all resulted in the same. (around 300GB, 180GB and 50GB respectively)

It seems like a similar issue to #14974

Steps To Reproduce

1. copy a folder
2. go to another directory and paste it
3. open the Status Center

It's a WD Purple 4 TB. I just bought it and was testing it out.
Here's the screenshot of the task manager while transferring files

An update to the issue
I was transferring smaller files this time, and it does show item count, but size processed is still 0B of 0

This may narrow down the issue I guess?

Can confirm the same behavior. Single files for me will show transfer speed, but folders and multiple files show no transfer speed and no size progress. Seems to happen with all transfers, however my main use case is transferring data to a NAS.

It appears to error in FileSizeCalculator.cs on line 93 at PInvoke.CloseHandle(hFile); in ComputeSizeRecursively.

https://github.com/files-community/Files/blob/main/src/Files.App/Utils/Storage/Operations/FileSizeCalculator.cs

A temporary hot fix is to remove that line, but isn't a proper fix.

The error appears to be only for Folders. Single files appear to transfer with the size no issue.
