Claims20
A handheld computer comprising:
- a CPU executing an operating system in which executable programs are directly accessed from a permanent data storage in a database format;
- where said database format applies equally to data files;
- and,
- file management software for use with said CPU for manipulation of files in non-palm file formats.
A method of manipulating files in a handheld computer, of the type which uses a palm operating system, the method comprising the steps of:
- providing a shared library for access by applications running on said handheld computer;
- said shared library including routines for interfacing a FAT file system with an operating system of the type otherwise incapable of opening non-palm file formats;
- providing a secondary storage media for storing files thereon in non-palm file formats;
- opening an application on said palm operating system with the use of permanent data storage directly accessible with the use of said palm operating system;
- and,
- opening a file from said secondary storage media, without loading said file into said permanent data storage directly accessible with the use of said palm operating system, by using said shared library.
An instruction set for use on a handheld computer, said instruction set including:
- operating system means for accessing files other than files in non-palm file formats;
- means for implementing an Ffs in a secondary storage media;
- and,
- means for interfacing said means for accessing files other than files in non-palm file formats with said means for implementing an Ffs in a secondary storage media.
