The implementation is now JSR-248 (MSA) compliant.
Added a new internal read buffer which speeded up the read operations.
Added support for multiple memory cards and hard drives.
The files in the work directory of the MIDlet suite are retained when the MIDlet suite is reinstalled or upgraded, if the RMS record stores are retained. See MIDP 2.1 specification, chapter '2.1.5 MIDlet Suite Update' (JSR-118 specification). In S60 3rd Edition FP 1 and the earlier versions the files were never retained.
A new InputStream has to be opened to
see the changes made by OutputStream if the InputStream has
already encountered EOF (end-of-file).
The Read/Write User Data Access groups give MIDlet suites the ability to read or write any data in a file or directory.
