Item too large for volume format

I’m baffled. I have actually a 16GB Kingston USB flash drive that I use on my Mac system and also I’m trying to copy a 5GB file onto it. It’s empty. But I store getting the error “can’t be copied because it’s also large”. What’s wrong and also just how execute I solve it?


I’ve viewed this error too and also what you’re absent is the critical last few words of the error itself. It actually claims “item can’t be replicated bereason it is too large for the volume’s format.” That “for the volume’s format” is crucial, because the majority of sellers — Kingston contained — ship flash drives through a default format of Windows (FAT). A little of digging reveals that the max filesize supported on the Data Allocation Table (FAT) version of the Windows file mechanism is 4GB. So even if the flash drive has actually tons and loads of accessible space, the sad reality is that your file is as well massive for the file format.

But there’s another opportunity that I see the majority of human being pilgrimage over through flash drives too, also once the records are smaller sized than 4GB, that you haven’t cleared your trash yet. It functions prefer this: You have an 8GB flash drive. You have actually 6GB of papers on it. You drag them all to the Trash, then examine your cost-free room. It’s 1.6GB. What? Empty your Trash and also it’ll both empty whatever trashed files you have actually on the computer itself and also the documents you’ve dragged to the Trash from your USB flash drive as well. Confutilizing, yes. And it’s true on both Mac and also Windows.

Now earlier to the file too substantial for the FAT format difficulty. Here’s the error message you’re most likely seeing:

As you deserve to view, if you miss the last few words, you deserve to be baffled how a file have the right to be dramatically smaller than the capacity of the thumb drive, yet still fail to copy.

To settle it, we’re going to must reformat the flash drive. That’s done by finding the “Disk Utility” routine that’s contained through Mac OS X in the “Utilities” folder within the “Applications” folder. It looks prefer this:

Launch it and you’ll view a list of all drives and also tools hooked up to your system:

Be careful right here. Pick the best gadget. Take your time below and make sure that you’ve selected the flash drive, not your major tough drive. Picking the latter would certainly be a finish disaster and also you’d hate me forever. So don’t do it.

You deserve to confirm by looking at all the stats at the bottom of the home window. Here’s what I check out for my Kingston drive:

*
Notice the file format is MS-DOS (FAT). MS-DOS? Really? Well, it’s at least a very early, fairly primitive file format from the Windows side of points, though I can’t imagine a solitary perkid still running MS-DOS on their computer!

Got the appropriate unit? Click on the “Erase” tab then pick “Mac OS Extfinished (Journaled)” — my recommendation for flash drive styles, though it does make it unreadable on a Windows PC — and enter a new name for the device if you’re so inspired:

*
Take an additional minute to quadruple examine that you’ve picked the right gadget and also click “Erase…”

Absolutely sure you’ve picked the correct device? Click on “Erase” to proceed…

After a few moments, it shouldn’t take also long, your USB thumb drive will certainly reappear on the Deskpeak via its brand-new name and you deserve to currently drag that 5GB file onto the tool for safekeeping. I’ll confirm by copying my very own 4.93GB file:

That’s all there is to it. If you want to retain Windows compatibility via the flash drive, you could have to format it on a Windows PC using the NTFS (Windows NT File System) format. For reasons that are a bit difficult to fathom, that’s not an option in Disk Utility on the Mac.
