| Méthode | Explication |
| clearcache () | Clears file properties and BLOB region cache. Call this method when an external process updates the file. |
| usebufferedreader () | Caches last read bytes. |
| usecachedfile ({blocksize}, {cachesize}) |
Uses least recently used (LRU) block cache for handling files on cloud. |
