+You can use the `stat` command from a client to see whether a directory is approaching the maximum size limit for directory metadata (320 MB).  If you reach the maximum size limit for a single directory for Azure NetApp Files, the error `No space left on device` occurs.   
 
 For a 320-MB directory, the number of blocks is 655360, with each block size being 512 bytes.  (That is, 320x1024x1024/512.)  This number translates to approximately 4 million files maximum for a 320-MB directory. However, the actual number of maximum files might be lower, depending on factors such as the number of files with non-ASCII characters in the directory. As such, you should use the `stat` command as follows to determine whether your directory is approaching its limit.
