Mass TAR installer?

Hello, I'm a newbie to ibproarade and have a couple questions regarding TAR installations.

1. I upload each TAR file into ./arcade/tar directory then via Admincp/arcade/add game I click on "Install" to add each game. The "Install all Games" doesn't work with most of my TAR's and duplicates the ones already installed. Is there another way to mass install multi TAR's?

2. After the game is installed, can I delete the original TAR file or do I need keep it in the /TAR folder?

3. "Going on question 2" If I have to keep my original TAR on the server, is there any way to make multi TAR directories that can be seen by ibProArcade? Example "TARa", "TARb", "TARc", etc. This is only to keep alphabetize TAR's so I can manage a clean Vbull.

I'm using v2.6.8 with VB3.8.4

Thanks in advance. Please keep in mind that I am a new user and have no clue what I am doing yet. lol

1. The "Install all games" works in 99% of the times here. I dunno about any other ways to do this. If you download games from www.ibpdownloads.com the mass-installation option should work just fine.
2. You can remove the original TAR-file from the /tar-folder after you have installed the game.
3. Not relevant because of number 2.
