Python CacheManager for houdini

Python scripts to copy files to another folder if its greater then maximus capacity .
Source this functions using  Houdini by Python Source Editor  then write down  this line in your Pre-Frame Script using python as main language

    hou.session.cacheCopyManager(hou.node('/out/geometry1'), 890409 , "/home/chrysl666/PROJECTS/TEMP")

this function needs a path to the ROP node , a maximus Size in bytes  and the destination folder
