I am working with a R-J3iB controller that has a PCMCIA slot used for backing up. I was going to purchase a compact flash card, a compact flash card adaptor and a USB compact flash card reader so that I can perform a backup. It might seem like a silly question but the compact flash card is 4GB in size and I have seen a couple posts saying that issues can occur if the compact flash card is bigger than 2GB. Is this the case or would it be fine to use a 4GB compact flash card?
Fanuc Backup compact flash card size.

Older partition formats had limits. MS-DOS's FAT format is limited to 2048MB. If you have a problem finding a CFdisk that is only 2GB, you should be able format the CFDisk with a FAT partition , not fat32, which would limit the partition to 2gb and should be readable.
Though I can not guarantee it, as I am speaking with my IT hat on not a FANUC one.

We were told by Fanuc that problems may occur if card is larger than 2GB, that's what we use all the time. We have never had an issue.

It seems like 2GB might be the limit and anything past that is a problem.

What model of compact flash card do you use. I'm seeing a lot of Transcend and they do a 2GB card thats half the price of a 256MB.

We use Verbatim.

I've successfully used 4gb cards even with RJ3's. I think the size limitation only applies to USB.
