Examples described herein generally relate to a computer device including a memory, and at least one processor configured to partition application files for multiple users of the computer device. The computer device creates a per-user location for a first user when installing an application package to an installation location. The application package includes a plurality of files for an application that are read-only for the first user. The computer device projects, via one or more filter drivers, installed package files from the installation location into the per-user location. The computer device receives a modification to the plurality of files for the application projected into the per-user location. The computer device writes at least one modified file into the per-user location. The computer device loads, during execution of the application by the first user, the at least one modified file from the per-user location for the first user.
