At the moment, while copying the files, every copied file is shown in the terminal log, even if the file didn't need to be copied (already existed in the destination) and shows 0 bytes.

For aesthetic reasons, those files can be omitted in the terminal logs, and only showing the new files copied.

As a result, if there are no new files to copy, it should show a message confirming this.

Also, the time taken to copy the files is a useful log to show in the terminal.

As of right now, the letter assigned to the SD by the OS is required to be manually inputted by the user. For example:

D:\DCIM\100MSDF

That starting D depends of how many other USB devices are currently connected to the device, so it's not always going to be the same letter.

When an incorrect drive is selected, the program just exits without any explicit explanation.
Needs to actually tell the user that the files were not found.

Use a JSON file to load basic configurations like:

1. Directory where the files will be copied to.
2. File types (.JPG, .MP4, ...) to ingest.
3. Pattern for sub-directories creation (yyyy-mm-dd, dd-mm-yy, ...)

Instead of creating a directory named after the current date, and copying all files to it, organize each file in a directory based on it's creation/modification date.

Research

Research if it´s possible to speed up file transfers with gorutines (Concurrency).
