Bug: Wrong numbers by copying or deleting

### Description

When I copy or delete a folder with many files inside, it shows wrong numbers.

For instance, "deleting 120456/96520 files". How can it delete more than the number of files inside?

### Steps To Reproduce

Copy or delete and look at the numbers.

### Requirements

Fix it

### Files Version

3.0.3

### Windows Version

Windows 11 Pro 23H2 22635.2700

### Log File

Same log as the previous reports

Start by reproducing the copy or delete operation described in the issue and inspect the code that calculates and displays progress counts. Confirm the reported totals against the actual files involved; done means the displayed numbers no longer exceed the folder's file count.
