This is a google app script I originally made to help me automate workloads such as ingesting report data from emails into specific folders within my drive. It originally spanned across a few different functions, but I have since refined it/condensed it down to one function so I could easily copy and paste it into other scripts.
Upon successful execution, the function will return the ID of the last folder in the specified path.
The function has three parameters you can pass to it with only one being required for successful execution.
| Parameter | Description | Required? | Usage |
|---|---|---|---|
| path | Specify the path to use | Yes | STRING - Seperate folders in path using "/" - folderFinder("hello/world/foo/bar") |
| altRoot | Specify an alternate starting point | No | STRING - The ID of folder or shared drive - folderFinder("hello/world", "folder ID") |
| mkDir | Allow the function to make folders where it can't find ones | No | BOOLEAN - Either true or false but defaults to false - folderFinder("hello/world", "folder ID", true) |
If you set mkDir to true, the function will create the folders in the path if they don't exist.
Example output from Google App Script:
In this case, mkDir was set to TRUE and the folders/directory didn't exist in my drive, so the function created them for me.
If you don't set this to true, the function defaults to false.
You can pass an alternate root to the function so that you can search for folders from a different starting point.
How To Find Folder IDs
Keep in mind that if you don't specify an alternate root, the function defaults to the script owner's drive root.
