What is a .MIGRATEDAPLIBRARY file?
The file extension .MIGRATEDAPLIBRARY refers to a "Migrated Aperture Library" file. This type of file is essentially a library containing digital photographs that were originally managed using Apple's Aperture software. Aperture was a photo editing and management application developed by Apple but has since been discontinued.
When users of Aperture upgrade their operating system to OS X 10.10.3 or later versions, their existing Aperture photo libraries are converted into this new format, .MIGRATEDAPLIBRARY. This conversion is part of the transition to using Photos, another image organization application developed by Apple that comes pre-installed with these later versions of OS X. The Photos app serves as a replacement for Aperture and offers similar functionality in terms of organizing and editing digital photos.
The .MIGRATEDAPLIBRARY file contains all the images that were previously in the user's Aperture library. Additionally, it preserves any edits or changes that were made to these images using Aperture. This ensures that users do not lose their work and can continue to access and modify their photos using the Photos app.
To open a .MIGRATEDAPLIBRARY file, you should use the Apple Photos application, which is included with OS X 10.10.3 and later versions. There is no need to download or install additional software, as Photos is part of the operating system. Simply double-clicking on the .MIGRATEDAPLIBRARY file should launch the Photos app and allow you to view and manage the contents of the migrated library.
