.SPARSEIMAGE File

The sparseimage file extension is associated with Mac OS X Disk Utility.

These sparseimage files are disk images created with the application.

The sparseimage images are very similar to DMG disk images, but their size is limited to the actual size of the data in them.

Encrypted sparseimage files are used by FileVault, a data protection app from OS X.

From OS X 10.7. Lion FileVault uses encrypted sparsebundle files.

This sparseimage file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.

Files with the sparseimage file extension can be found as special disk images created using the Apple Mac OS X Disk Utility. Similar file format to DMG format.

How to open:

Use Apple Mac OS X Disk Utility to open these *.sparseimage disk image files.

How to convert:

Using Apple Disk Utility it should be possible to expand the image back to ISO or DMG.
