One way to do that is with a simple search. Go to the Attachments folder in the Finder. Then Command+f to search. At the top you should see 'Search:' and then 'This Mac' and 'Attachments.'.
To get a list of child objects (folders and files) in a directory, use the Get-ChildItem PowerShell cmdlet. This is the most popular file system cmdlet. There are several aliases for ChildItem: gci, dir, ls.
- I am wondering if it is possible to extract files from folders on an automated basis. I can manually go and and extract these but lets be serious, that is going to take a long time.

However, it displays a list of objects located in the root of the specified directory. You can also display the contents of child directories using the –Recurse parameter:
As you can see, the contents of each subdirectory are displayed sequentially.
Now, let's look at the general structure of the ForEach loop when using the Get-ChildItem cmdlet:
Also, you can use such a loop structure (but we like it less):
For example, you can delete all files with the *.log extension in the specified directory and all subfolders (we won't really delete the files from disk by adding the parameter
The script found 3 files with the extension log and indicated that they could be deleted by this script.

The following file loop example allows to find files containing the text ‘flush_log' or ‘error' for all *.log files in the directory, and saves the found lines to files with a new extension (_outlog): Mac os system update.
