			------------------

diskload ( FromDisk ToMem amount -- )
                Load specified abount of bytes from disk into memory.

disksave ( FromMem ToDisk amount -- )
                save specified abount of bytes from memory into disk.

format ( -- )   Erase all files.

fsDfilesize@ ( handle -- size )
                Return size of opened file.

fsDcurloc@ ( handle -- location )
                Return current location in file.

fsDupdated@ ( handle -- updated? )
                Return true if file was updated,
                ie. write operations occured.

fssave ( FromMem DestFileHandle amount -- )
                Save data to file.

fsload ( SrcFileHandle ToMem amount -- )
                Load data from file.

fseof ( handle -- bytesLeft )
                Return amount of bytes left till end of file.
                Useful before read operation.

fsls ( -- )     List all files and lists (directories,folders)

fslsr ( -- )    Same as "fsls" but recursively scans also sub lists.

fscl ( DynStrHand -- )
                Change list (path)

fscreate ( DynStrHand -- DescPnt )
                Create new file or list. Can create multiple lists at once.
                ex: when creating:
                    "\listGAMES\listSTRATEGY\listSIMWORLD\5th-runme"
                and only "\listGAMES\" already exist, then
                "listSTRATEGY" and "listSIMWORLD" lists will be created,
                and empty file "5th-runme" placed in there.

fsDsave ( DynHand<data> DynStrHand<filename> -- )
                Create new file and save all data from dynamic memory
                block to it.

fsDload ( DynStr<SrcFileName> DynHand<DataDest> -- )
                Load whole file into dynamic memory block.

fsDloadnew ( DynStr<SrcFileName> -- DynHand<DataDest> )
                Load whole file into new dynamic memory block.
