如何在我的谷歌硬盘的特定文件夹中查找重复文件(按名称和/或大小)？

Question

是否可以创建一个谷歌应用程序脚本,它将选择自动复制特定(当前)文件夹中的文件(然后我只需要一次点击就删除它们)？

https://developers.google.com/apps-script/reference/drive/

我问这个是因为谷歌驱动器PC客户端在更新时会创建随机重复文件!他们想要解决这个错误,但我必须在每个文件夹中手动选择它们然后删除它们.这非常烦人且耗时. https://productforums.google.com/forum/#!category-topic/drive/report-a-problem/_ApOopI-Xkw

编辑:或者,由于Windows无法在同一文件夹中创建相同的文件名,因此在特定主文件夹(及其每个相关子文件夹)中查找并放入垃圾桶中的所有重复文件名.

Answer 1

为了更好的可读性,我在第二个答案中添加了这个答案的下一部分.

以下是处理重复项的代码:它分两步进行:

1. 检测重复项并在表单中标记它们以检查一切是否正常(markDuplicates())
2. 删除要保留的文件的红色背景(在完成第3步后它们将变为黄色)
3. 删除选定(标记)的文件,实际上将它们移动到垃圾箱,你必须从驱动器Ui手动清空垃圾箱.(trashDuplicates())删除的文件将以深红色显示以确认删除.

在此处放置完整代码并将某些函数设置为私有以避免由于错误的脚本调用而导致的错误.
