Object store filesystem type!

Hi there,

I have Windows CE 5.0 BSP and my image is downloaded to RAM and
executed from RAM. I understand that in Windows CE 5.0 Total RAM is
divided into Storage Memory and program memory. And storage memory is
used for storing files that we transfer and by means of activesync or
some other. I want to know what filesystem is basically mounted on
this storage memory? Is it FAT/TFAT?

Thanks

Hi,

The object store has it's own RAM file system driver. The following
pages describe how this fits in with the file system architecture:

Hi Rik,

Thanks. I have two questions:

1) The above link (1st ) talks about windows CE 6.0. Is this
applicable for Windows CE 5.0?

2) I have mounted NAND flash as root and using FATFS. So is there
anyway I can get rid of RAM filesystem and object store? If I have
mounted external filesystem as root, then what for object store is
used?

Also currently I have left very small amount of memory for object
store which is shown by Control Panel --> Memory applet. Is there
anyway I can show my NAND flash space here instead of object store?

Thanks

1. For all versions of CE, it is true that the object store uses a different
file system type than FATFS. The link you asked about has some CE6 specific
content though, because only on CE6 can you mount the object store as a
drive below the root. On CE5 and previous versions, you only had a choice
between having the object store as the root, or having no object store.

2. Yes, you can get rid of the RAM file system. The object store will
always exist slightly, at its minimum size (28KB? I forget). However the
memory applet cannot be changed to show your FATFS drive as "storage
memory." The memory applet comes from older times when you were simply
dividing RAM between storage and program memory. When you're using flash,
there's no "division," all of your RAM is program memory.
