Google Drive - Files or folders lost after moving around

If you move files or folders around your Google Drive in the web interface, you may lose them. They just disappear mysteriously.

According to a discussion thread on Google Group, this issue has been arround for almost 2 years. And there are some ways may help you to get those files/folders back:

0. Wait for 24h and your files/folders may be back (from nowhere).

1. Search in the Trash.

2. Search with "<name of the files or folder>*" keywords.
