Y81 Dump File File

Look for:
A y81 dump file is a binary snapshot of a process’s memory space, CPU registers, and stack traces at the moment of a critical failure. The "y81" designation is not a universal standard (like Windows .dmp files) but rather a proprietary naming convention. Based on forensic analysis of systems where this file appears, the "y81" suffix typically originates from one of three origins: y81 dump file
Unlike a minidump (which saves only essential information), the y81 dump file is typically a full user-mode dump, meaning it can be several hundred megabytes or even gigabytes in size.
