Parted (multi-part) storages
In SolFS 5 and later container file can be split to several parts (eg. to store parts on the FAT filesystem which limits files to 4 Gb size). For example, if you plan the storage to be 16Gb large, you can split it to 4 (four) 4Gb-large parts.
Part size is specified when the storage is created and can not be changed later.
