can I delete these?

If this is an issue with Lack Free Space on this computer

Reducing System/Volume/Data is a common question. 

1 -  System data taking too much in MacOS Sono… - Apple Community

2 - Time Machine Local Snapshot won't delete - Apple Community

3 - Over 60% storage blocked by System Data - Apple Community

How to free up ‘System Data’ and other storage on your Mac from a fellow colleague  

Suggest getting an External SSD Drive and start moving your Pictures, Videos, Music and any other large files you have control over, OFF the Internal drive and Onto the External

There are  two effective ways to remedy this issue:

1. Quick Fix Actions:

For Apple Silicon computers, use Disk Utility to erase a Mac.

For Apple Intel computers, use Disk Utility to erase an Intel-based Mac, then reinstall macOS.

Always make a Time Machine backup before proceeding.

Migrate only the user account, not the entire system.

Reinstall only the necessary applications from the Apple App Store or directly from the developers.

2 - Generally

When the user discovers this issue, it’s likely because the computer’s internal drive capacity is small, such as 256 GB or 512 GB. Unfortunately, the user’s storage needs may have increased since the computer was purchased. To future-proof the computer, consider spending extra money upfront on a larger drive capacity and adding more unified RAM.

Note - On Apple Silicon and newer computers. The SSD Drive and the Unified RAM are Soldered to the Logicboard and can not be upgraded.

thanks but that doesn't say what i can and i cant delete

The file path component NSIRD_com.apple.CloudDocs.iCloudDriveFileProvider_zgA12M is a temporary or cache folder name associated with iCloud Drive functionality on macOS. 

Here is a breakdown of the name's components:

com.apple.CloudDocs.iCloudDriveFileProvider: This is a bundle identifier used internally by macOS to represent the iCloud Drive service, which manages file synchronization and storage in the cloud. The "FileProvider" framework is the modern system used by cloud storage services (like iCloud, Dropbox, and Google Drive) to integrate with the macOS Finder.

NSIRD_: This prefix, along with the trailing alphanumeric characters like _zgA12M, suggests it is a system-generated, temporary, or unique identifier for a specific session or process related to the synchronization.

Purpose: Folders with names like this often contain temporary data, synchronization logs, or locally downloaded file chunks (a cache) that are part of the process of moving files between your local Mac and Apple's servers. 

These folders are typically located within system library directories (e.g., ~/Library/Application Support/CloudDocs or a similar path) and are managed automatically by the operating system.

They are generally not intended for direct user interaction and are safe to ignore. 

If this folder is consuming a significant amount of local storage, macOS's optimized storage feature should manage it automatically.

That might be iCloud Drive file sync, or a malfunction with it.

If considering deletion, I'd absolutely not delete those until after copies of all of iCloud Drive files are stored elsewhere.

And I'd probably then first sign out of iCloud and back in, and see if things resolved.

If you're running close to the storage capacity as is common in these cases, corruptions are possible, too.
