MacOS – Remove disk image from the disk list

disk-utilityhard drivemacos

In Disk Utility I see two disk images (Flash Updates)

enter image description here

But I cannot find where the image file could be.

On the console with diskutil I see

/dev/disk2 (disk image):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:     Apple_partition_scheme                        +16.9 MB    disk2
   1:        Apple_partition_map                         32.3 KB    disk2s1
   2:                  Apple_HFS Flash Player            16.9 MB    disk2s2
/dev/disk4 (disk image):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:     Apple_partition_scheme                        +17.2 MB    disk4
   1:        Apple_partition_map                         32.3 KB    disk4s1
   2:                  Apple_HFS Flash Player            17.1 MB    disk4s2

And with diskutil info

   Device Identifier:        disk4
   Device Node:              /dev/disk4

Is there a way to know where these images are on my disk?

hdiutil will show information about all mounted DMGs:
