Why does the file creation date remain the same when copying and pasting a file?
This is because the GUI copy function on macOS preserves all attributes by default.
To put it in command line terms:
When you copy and paste a file in macOS, by default its doing this:
cp -a /source/file1 /destination/

which preserves attributes such as permissions and timestamps.
The only workaround for this (i.e., to achieve Windows-like behavior) is to copy files using the command line. Applications -&gt; Terminal.app
and use the following command:
cp -r /source/file1 /destination

Alternatively, you can simplify the process by allowing terminal to get file paths by simply dragging and dropping the source file and the destination folder:

Search
Type &quot;Terminal&quot;. Press return
Type cp -r 
Drag and drop the source file
Drag and drop the destination file
Press return again.
