>Yes i have no security on any of my folders. It is using fat32.

Yep. FAT32 doesn't offer security, in the sense of access rights!

The non-NTFS workarounds are to block physical access access to the PC
and apply access security at the network share level, or to apply
application-specific pwd at file level (if supported by app)

>so if i change the file system to NTFS will it affect the computer in any way?

Yes it may do, in that NTFS's added security can permeate the file
system and cause unexpected glitches with software that was written
for Win9x. For example, apps that write to settings or data files
within "Program Files" may not be permitted to do so.

However, these factors usually don't apply when converting from FATxx
to NTFS after installing the OS, because it's when installing the OS
that many of these specific security permissions are devised and
applied. When the OS is installed on FAT32, these settings cannot be
applied as FAT32 doesn't support this; so when the file system is
later converted to NTFS, all files get the same open-boot access.

>Anf will it jsut be My Documents that is changed to this file system?

No. File systems apply to the entire volume (in fact, you can define
"volume" as an extent of a file system). So applying NTFS to a drive
letter will affect the entire drive letter.

This operates at a lower level of abstraction than network drive
letter mappings and Subst - so you cannot, for example, define E: as a
subst for "My Documents" and then convert E: to NTFS to limit the
effect to that subtree alone.

File system details are invisible to network access, so the concept of
mapping a drive letter to a share of "My Documents" and then
converting that drive letter to NTFS is meaningless.
