The -createchunkinstall option is used to separate out chunk>0 CDN/patch data from the main packaged app, but when using it with the IOStore enabled, only the pak files are separated out but not the utoc/ucas files. This appears to be an oversight.
The CDNChunks\Windows\1.0\pakchunk1001 folder contains the chunk 1001 pak file, and the Windows folder contains the pak0's file as well as chunk 1001's utoc/ucas files.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-172550 in the post.
