>             Project: Ignite
>          Issue Type: Task
>          Components: IGFS
>    Affects Versions: 1.5.0.final
>            Reporter: Vladimir Ozerov
>            Assignee: Vladimir Ozerov
>             Fix For: 1.7

> *Problem*
> Currently our metadata appears to be too heavy. 
> Short summary of {{IgfsFIleInfo}}:
> {{id}} - files and dirs 
> {{len}} - only files
> {{blockSize}} - only files
> {{props}} - files and dirs
> {{lockId}} - only files
> {{affKey}} - only files
> {{fileMap}} - only files
> {{accessTime}} - files and dirs
> {{modificationTime}} - files and dirs
> {{listing}} - only dirs
> {{evictExclude}} - only files
> The same applies to {{IgfsListingEntry}}
> *Solution*
> 1) Split files and directories into separate classes. This will improve both performance and maintainability of {{IgfsFileInfo}} class.
> 2) Investigate whether we need {{IgfsListingEntry}} at all. It looks like we only need it for "listPaths" operation. Can we simply replace it with "String -> IgniteUuid" map?
