Please, add the ability to accept command line argument to have faster and convenient way to download/upload files and folders.

Describe the solution you'd like to see.

Examples:

should recognize 1st argument as a file and automatically start uploading it.

rymdport.exe "C:\...\folder"
should recognize 1st argument as a folder and automatically start uploading it.

rymdport.exe 4-backwater-spin
should recognize 1st argument as alias and automatically download the appropriate file or folder.
