Question Why file hash changes?
I use "connect to folder" or "save to disk" feature to copy the ebook files to a specific folder which is used for Syncthing to sync them with other devices I noticed whenever I connect to folder & copy some files...the ebook file hash changes but it doesn't change if I simple copy-paste or drag & drop from Calibre to a specific folder of FileManager. Why is that?

Save to Disk, and Send to (device) folder are not simple copies. See the Preferences for each - e.g. Update metadata in saved copies.

The default is for the metadata to be updated when you save to disk. This can be turned off.

What is the settings to achieve similar behavior for "Connect to Folder"?

Sending books to a device including the folder device always updates metadata in them.
