These are the sample scripts of the batch requests for Drive API using Google Apps Script.
When we want to manage the files and folders on Google Drive, we have 2 ways. One is the use of Drive service. Another is the use of Drive API. In the case of them, when we want to manage a lot of files and folders, unfortunately, both ways have no batch requests. Namely, for example, the metadata of a lot of files are changed, the methods in Class File and Files: update are required to be used in the loop. In this case, the process cost will be high. On the other hand, Drive API can use the batch requests. But in this case, in order to use this batch requests with Google Apps Script, it is required to create the request body of
multipart/mixed by each user. Because there are no methods for automatically requests the batch requests. From this situation, here, I would like to introduce the simple sample scripts for creating, updating and deleting the files and folders on Google Drive using the batch requests with Google Apps Script.
