- Cleaned up some allocations caused by string manipulation. *Add a place for shared utility code that could have use in multiple places in the virtualization system. - First utility is a function to generate a file path based off a FPayloadId. - The path produced is similar to how we organize files in the DDC but instead of 0->9 we use the range 0->ff in hex. - To generate the path we take the string form of FPayloadId and then use the first 6 characters to create the directories (each directory using 2 characters) and then the remaining 34 characters becomes the filename. #rb Stefan.Boberg #rnx #ushell-cherrypick of 16167644 by paul.chipchase #preflight 608f9330f5b27a0001b2d5ab [CL 16182581 by paul chipchase in ue5-main branch]
