A virtual machine of an information handling system (IHS) initializes an operating system to provide partition file system memory management during application execution. The operating system employs multiple partitions that include one or more applications for execution within the virtual machine. A file system tool identifies write operations to a global file system and generates local and common file system information. The file system tool populates the local file systems that include delta local file systems and differential file systems with write operation data. The file system tool may generate stackable common delta file system information to store write operation data common to two or more partitions that employ executing applications. The file system tool may combine or separate stackable common delta file system information to provide improvements in virtual machine memory utilization.
