Google Drive is a popular cloud storage and synchronization service that allows users to store and access files from any device with an internet connection. However, users may encounter issues such as deleted files or difficulty accessing documents. To address these issues, there are several solutions available online. In this regard, I came across to an informative article that highlights the three best manual methods for how to retrieve documents from Google Drive. These methods include:

Method 1: Restore Deleted Files in Google Drive Using Bin
Method 2: Retrieve Documents from Google Drive Using Ctrl + Z
Method 3: Recover Deleted File from Shared Folder Google Drive

Additionally, the article recommends an advanced software solution, the Google Drive Migration Tool, which provides a secure and efficient way to backup and migrate Google Drive data to local drives or another Google Drive. This tool helps users to free up server space and better manage their Google Drive after the migration process. A free demo version of the tool is available for users to try out.
