Windows tool XCOPY: File metadata preservation issue

[infeo]

System Setup

OS: Windows 10 Pro N 2004
Adapter-Version: 1.1.15
Dokany: 1.4.0

Description

When copying files to the vault with the Windows tool xcopy, it seems that some metadata is not copied along. This holds only for certain file types (e.g. .txt or .msi) while others ( .jpg, .pdf) are not affected.

Steps to reproduce

1. Mirror a directory to a mountpoint (e.g. E:).
2. Create a temporary-folder with some example data
3. Use a Windows Command prompt to run:
   XCOPY temporary-folder E:\Test /E /D /I /Y /V
4. Run the same command a second time:
   XCOPY temporary-folder E:\Test /E /D /I /Y /V

Expected result

The second time no file is copied

Actual result

Some files are copied again.
