I'm not sure what to make of this, if you really don't know or just can't be bothered to upload.
Making a RAR file is so easy a loli could do it themselves even:
1. Have directory ready you wanna rar.
2. Open WinRAR
3. Select directory and click "ADD"
4. Get a whole bunch of options in tabs, like what to name your rar.
5. Go trough options, says also "SET PASSWORD" set it.
6. Click okay or RAR or whatever the heck it says, wait till its finished.
7. Presto, you just made a rar, now upload the bastard.
