闪存驱动器

You have a brand new high-capacity flash drive that can store more than the hard drive of your first three computers combined, but when you go to copy a large file it denies you. What gives? Read on as we show you how to solve your flash drive frustrations.

您有一个全新的大容量闪存驱动器，可以存储的容量比前三台计算机的硬盘驱动器总和还多，但是当您复制大文件时，它会拒绝您。 是什么赋予了？ 请继续阅读，我们会向您展示如何解决闪存驱动器的问题。

Dear How-To Geek,

亲爱的How-To Geek，

I recently purchased a 64GB USB 3.0 flash drive, plugged it into my computer, and started copying some files onto it I wanted to transfer to another computer. The little files (MP3s, documents, etc.) all transferred fine but I have some DVD ISO files on there and when it came time to copy them I got the error “The file ‘DVDBACKUP1’ is too large for the destination file system.” and the transfer fails.

我最近购买了一个64GB USB 3.0闪存驱动器，将其插入我的计算机，然后开始将一些文件复制到该文件上，以将其传输到另一台计算机。 小文件(MP3，文档等)都可以正常传输，但是我那里有一些DVD ISO文件，当需要复制它们时，出现错误“文件'DVDBACKUP1'对于目标文件系统来说太大。 ” 并且传输失败。

What exactly does that error mean? Why can’t I put a 4.5GB file on a 64GB drive? Help!

该错误到底是什么意思？ 为什么不能将4.5GB的文件放在64GB的驱动器上？ 帮帮我！

Sincerely,

真诚的

Flash Drive Frustrated

闪存驱动器沮丧

We can certainly understand your frustration: here you were all ready to copy the files and then it just ground to a halt with a relatively cryptic message. Don’t worry though! We can not only solve the mystery of the stubborn file but show you how to fix it in the process.

我们当然可以理解您的无奈：在这里，您已经准备好复制文件，然后由于相对神秘的消息而停顿了下来。 不过不要担心！ 我们不仅可以解决顽固文件的奥秘，还可以向您展示如何修复此文件。

First, let’s explain why you couldn’t copy it in the first place: the flash drive’s file system. A file system, which is a separate thing from an operating system and other mechanisms on a computer, is an organizational scheme used to control how data is stored and retrieved on a a given storage medium (like a hard disk, a DVD disc, or a removable flash drive). There are a multitude of file systems in the world that have features big and small that are useful (and even mission critical to the applications they are used in) such as native error checking and correction, journaling, permission schemes, and more.

首先，让我们解释一下为什么不能首先复制它：闪存驱动器的文件系统。 文件系统是与操作系统和计算机上的其他机制不同的文件系统，是一种用于控制如何在给定的存储介质(例如硬盘，DVD光盘或磁盘)上存储和检索数据的组织方案。可移动闪存驱动器)。 世界上有许多文件系统，它们的大小不一，它们很有用(甚至对于使用它们的应用程序来说是至关重要的)，例如本机错误检查和更正，日记记录，权限方案等。

Nearly every flash drive in the world ships formatted as with the FAT32 file system. FAT32 isn’t the most robust file system around but it has been around for ages, it is widely supported, and most of the time the applications one would use a flash drive for do not require the advanced features found in other file systems (and, in fact, some of those advanced features could even shorten the life of the drive via increased read/writes). If you’re curious as to why FAT32 is still so prevalent, check out our article HTG Explains: Why Are Removable Drives Still Using FAT32 Instead of NTFS?

世界上几乎所有的闪存驱动器都采用FAT32文件系统的格式进行格式化。 FAT32并不是目前最强大的文件系统，但是它已经存在了很长时间，并且得到了广泛的支持，而且大多数时候应用程序将使用闪存驱动器不需要其他文件系统中的高级功能(并且，实际上，其中一些高级功能甚至可能通过增加读/写来缩短驱动器的使用寿命)。 如果您对FAT32 为何如此流行感到好奇，请查看我们的文章HTG解释：为什么可移动驱动器仍然使用FAT32而不是NTFS？

Despite the ubiquitous nature of FAT32, however, it has one big shortcoming in the age of large files: the maximum possible file size for FAT32 files is 4GB. (If we’re being technical it’s actually 4GB minus a single byte or 4,294,967,295 bytes). These days 4GB isn’t exactly a whopper of a file and it’s real easy, as you discovered, to exceed the 4GB barrier with large video files, DVD and Blu-ray ISOs, and other large files.

尽管FAT32具有无处不在的性质，但是它在大文件时代存在一个很大的缺点：FAT32文件的最大可能文件大小为4GB。 (如果我们是技术人员，则实际上是4GB减去一个字节或4,294,967,295字节)。 如今，4GB并不完全是文件的浪费，正如您所发现的那样，对于大型视频文件，DVD和Blu-ray ISO以及其他大型文件，要突破4GB的障碍确实很容易。

Now that we know why you can’t copy that DVD ISO file over to your nice spacious 64GB flash drive, what can we do about it? Fortunately the fix is very simple. We’ll switch the file system to a file system which allows for larger-than-4GB file sizes.

现在我们知道了为什么不能将DVD ISO文件复制到宽敞的64GB闪存驱动器中，我们该怎么办？ 幸运的是，修复非常简单。 我们将文件系统切换为允许4GB以上文件大小的文件系统。

We’ll demonstrate with a 16GB flash drive we have laying around. The flash drive is formatted in FAT32 and if we attempt to copy a 7.63GB ISO file, as seen in both the screenshot above and the header image for this article, we get the same error you got the file is “too large for the destination file system”.

我们将展示一个16GB的闪存驱动器。 闪存驱动器采用FAT32格式，如果我们尝试复制7.63GB的ISO文件(如上面的屏幕截图和本文的标题图像所示)，则会遇到相同的错误，即文件“对于目标而言太大”文件系统”。

To remedy that situation we’ll ensure there is no data on the flash drive that needs to be copied back to the machine or backed up and then we’ll format it to the NTFS file system (which allows for files ranging in size from 128GB to 256TB depending in the implementation used, more than enough for your needs).

为了解决这种情况，我们将确保闪存驱动器上没有需要复制到计算机或备份的数据，然后将其格式化为NTFS文件系统(允许文件大小从128GB开始)到256TB，具体取决于所用的实现方式，足以满足您的需求)。

We can swap out the file system by simply selecting the drive in Windows Explorer via right-click and then, in the right-click context menu, selecting “Format…”

我们可以通过在Windows资源管理器中通过右键单击选择驱动器，然后在右键单击上下文菜单中选择“格式化...”来换出文件系统。

In the Format menu, as seen above, change the file system from “FAT32” to “NTFS”. Leave the “Allocation unit size” at the default of 4096 bytes. Check “Quick Format”. Click “Start” to format the drive with a new file system.

如上所示，在“格式”菜单中，将文件系统从“ FAT32”更改为“ NTFS”。 将“分配单位大小”保留为默认的4096字节。 选中“快速格式化”。 单击“开始”以使用新文件系统格式化驱动器。

Now that we’re sporting a large-file-friendly flash drive it’s time to transfer a large file and see what happens.

现在我们正在使用大文件友好型闪存驱动器，是时候传输大文件并查看会发生什么了。

Success! Now that the flash drive is formatted to NTFS it has no issue accepting a 4+GB file size and we’re able to transfer that 7.63GB ISO with ease. Your super sized flash drive is now ready to accept super sized files.

成功！ 现在，闪存驱动器已格式化为NTFS，接受4GB以上的文件大小没有问题，并且我们能够轻松地传输7.63GB的ISO。 现在，您的超大容量闪存驱动器已准备就绪，可以接受超大容量文件。
