Google 云端硬盘(Google Drive)已成为在客户、同事和朋友之间共享文件的最佳和最受欢迎的方式之一，无需他们直接下载。
十年前，您会将这些文件作为电子邮件附件或链接从Megaupload或MediaFire等网站发送。让我们都为那些日子已经过去而感到高兴。
那些旧网站上的一个流行功能已经延续到今天流行的共享网站，如Pastebin，是在一段时间后使您的链接无效或取消共享您的文件的能力。这不是我们可以通过电子邮件做的事情。但是，这是许多人在Google Drive(Google Drive)中不知道的功能。
一些敏感文件不应该永远存在于
互联网(Internet)上。在本文中，我们将讨论如何为您在Google Drive中的共享文件访问设置过期日期。
Google Drive中共享文件访问过期的限制
请务必了解，此功能仅适用于付费G Suite组织下的帐户。这意味着标准Google帐户或使用免费旧版G Suite的帐户
不能使用共享文件访问到期。
不属于付费G Suite
组织的用户仍然可以将文件共享给他们，但必须满足此要求才能在 Google 云端硬盘中设置共享文件访问权限。如果您所在的公司通过自定义Gmail(Gmail)域为您分配了自己的电子邮件帐户，那么您很有可能可以通过该帐户访问此功能。
如何在Google Drive(Google Drive)中设置共享文件访问期限
自然，此过程的第一步是与某人实际共享文件。要在 Google 云端硬盘中共享您的某个文件，最简单的方法是访问该文件，然后查看右上角的蓝色大共享(Share)
按钮——您不会错过它。
单击(Click)它，将弹出一个灯箱，您可以在其中输入电子邮件地址列表以与之共享文件。
准备好后，单击“确定(OK)”按钮发送共享文件的邀请。之后，您需要重新打开同一个文件并再次单击蓝色的Share按钮或右键单击该文件并单击Share。这一次，单击灯箱右下角的高级。(Advanced)
在这里，如果您将鼠标悬停在与您共享文件的任何用户所在的行上，当您将鼠标悬停时，会出现一个计时器图标，上面写着“设置过期(Set expiration)”。如果您没有看到此图标，则可能表示您没有使用兼容G Suite组织下的帐户。如果你这样做，请单击它。
您可能看不到它的另一个原因是Google更新了Google Drive的(Google Drive)GUI界面。相反，您可能必须单击他们姓名旁边的小下拉菜单，然后单击授予临时访问权限(Give temporary access)。
现在你会看到一个像下面两个这样的窗口。最上面的图片是较新版本的Google Drive，很可能是您会遇到的。
这应该会导致出现访问过期选项。单击下拉菜单将显示 7 天和 30 天的常用日期，或者您可以单击自定义日期...(Custom
date…)设置您自己的到期日期。
设置自定义日期将允许您从日历视图中选择一天。唯一的问题是您无法选择时间，只能选择日期 - 该文件将在您选择的任何一天的午夜前一分钟到期。
一旦您对配置共享文件访问到期的方式感到满意，请点击保存更改(Save
changes)，然后点击完成(Done)。就是这样！
要记住的重要一点是，用户仍然可以通过下载文件来有效地保持文件超过其到期日期。为了防止这种情况发生，您需要将他们的访问权限设置为只允许他们查看文件（而不是编辑文件）并启用“禁用选项以供评论者和查看者下载、打印和复制(Disable options to download, print, and copy for commenters and viewers)”选项。
如果您拥有非旧版 G Suite 组织下的帐户，则共享文件访问到期是您可以充分利用的众多未充分利用的特权之一。这只需要几秒钟，所以不要让那些敏感文件永远存在！

Set an Expiration Date on Shared Google Drive Files
Google Drive has emerged as one of the best and most рopular ways of ѕharing files between clients, coworkers, and friends without requiring them to make a direсt download.
A decade ago, you’d be sending these files as an email attachment or link from a site like Megaupload or MediaFire. Let’s all rejoice that those days are behind us.
A popular feature on those sites of old that
has carried over into today’s popular sharing sites, like Pastebin, is the
ability to invalidate your link or unshare your file after a set period of
time. This isn’t something we can do via email. However, it’s a feature that
many people aren’t aware of in Google Drive.
Some sensitive files shouldn’t live on the
Internet forever. In this article, let’s talk about how you can set an
expiration date on your shared file access in Google Drive.
Limitations of Shared File Access
Expiration in Google Drive
It’s important to know that this feature is
only available for accounts under a paid G Suite organization. This means that
standard Google accounts or accounts using the free legacy version of G Suite
can’t utilize shared file access expiration.
Users who are not under a paid G Suite
organization can still have files shared to them with an expiration, but this
requirement must be met to set the expiration of shared file access in Google
Drive. If you work for a company that assigns you your own email account
through a custom Gmail domain, there’s a good chance that you have access to
this feature through that account.
How to Set Up Shared File Access
Expiration in Google Drive
Naturally, the first step of this process is
to actually share a file with someone. To share one of your files in Google
Drive, the easiest way is to access the file and then look in the top-right
corner for the large blue Share
button—you can’t miss it.
Click on it and a lightbox will pop up that
will allow you to type in a list of email addresses to share your file with.
Click the OK button to send out your invitation(s) to share your file when you’re ready. After, you’ll want to reopen this same file and again click on the blue Share button or right-click on the file and click on Share. This time, click on Advanced in the bottom-right corner of the lightbox.
Here, if you hover over the row of any of the users you’re sharing the file with, a timer icon will appear that reads “Set expiration” when you hover it. If you don’t see this icon, it could mean that you aren’t using an account under a compatible G Suite organization. If you do, click on it.
Another reason you may not see it is because Google has updated the GUI interface for Google Drive. Instead, you may have to click on the little drop down next to their name and then click on Give temporary access.
Now you’ll see a window like the two below. The top image is the newer version of Google Drive and most likely what you’ll encounter.
This should cause the access expiration
options to appear. Clicking on the dropdown menu will reveal common dates of 7
days and 30 days, or you can click on Custom
date… to set your own expiration date.
Setting a custom date will allow you to select
a day from a calendar view. The only catch is that you’re not able to select a
time, only a date—the file will expire a minute before midnight on any day that
you select.
Once you’re happy with how you’ve configured
your shared file access expiration, click Save
changes and then Done. That’s
it!
An important thing to keep in mind is that
users will still be able to effectively keep your file past its expiration date
by downloading it. To prevent this, you’ll want to set their access to only
allow them to view the file (not edit it) and enable the “Disable options to download, print, and copy for commenters and viewers”
option.
If you have an account under a non-legacy G
Suite organization, shared file access expiration is one of the many underused
perks that you can put to great use. This only takes a matter of seconds, so
don’t let those sensitive files hang around forever!
