Windows sometimes freeze while calculating the time needed to copy files

When I copy or move large files and folders in Windows File Explorer, the progress dialog frequently freezes or becomes unresponsive while calculating the remaining time, forcing me to wait or cancel the operation entirely. This issue occurs intermittently and seems unrelated to file size or drive type, and I would like to know if there is a known fix or workaround to prevent these freezes during file transfers.

    The core of the problem is a design choice in Windows. Before copying any data, File Explorer first enters an enumeration phase.

    Real-time scanning of every file during the transfer can dramatically slow things down, especially with large executables or videos.
