Forech Iteration on FileSize List to Obtain a sublist of file of a certain Size

Question

Given a list of files, having obtained the list of their relative sizes, I have to iterate on the list until I obtain a maximum size (for example 10MB) and from the next file start again with the same process, iterating until the end of the list

Something like this? You will have to adapt this to your specific use case. 
 
 a!localVariables(
 local!lastZip: ri!map.zips[count(ri!map.zips)],
 if(
 local!lastZip.size + ri!file.size > 1000000,
 a!update(
 ri!map,
 "zips",
 append(
 ri!map.zips,
 a!map(files: {ri!file.name}, size: ri!file.size)
 )
 ),
 a!update(
 ri!map,
 "zips",
 a!update(
 ri!map.zips,
 count(ri!map.zips),
 a!map(
 files: append(local!lastZip.files, ri!file.name),
 size: local!lastZip.size + ri!file.size
 )
 )
 )
 )
) 
 
 a!localVariables(
 local!files: a!forEach(
 items: enumerate(rand() * 100),
 expression: a!map(name: char(64 + fv!index), size: rand()*100000),
 ),
 reduce(
 rule!SSH_ZipBuilderHelper(map:_, file:_),
 a!map(
 zips: {
 a!map(files: {}, size: 0)
 }
 ),
 local!files
 )
)
