fs-nt.so

Shared object that supports the Windows NT filesystem (QNX Neutrino)

Syntax:

driver … nt nt_options… &

Runs on:

QNX Neutrino

Options:

compress=number
The number of buffers to use for the dynamic decompression of compressed files (e.g. if in a directory you set the “Compress contents to save disk space” folder attribute). The default is 2; a value of 0 disables support for compressed files.
dots=off|on
Fabricate . and .. directory entries. The default is off.
lnk=lnk_mode
Set the handling of NTFS reparse points. The options are:
  • ignore — treat a reparse point as a regular file of zero length.
  • all — if a segment of a path is a reparse point, replace the segment with the reparse point's content (the default).
hidden=dot|ignore|show
Specify what to do with files that have the NTFS “hidden” attribute:
  • dot — show hidden files in the filesystem with a dot (.) prefixed to their names. Files created with a leading dot have the NTFS “hidden” attribute set.
  • ignore — ignore hidden files; the files don't appear in the filesystem.
  • show — show hidden files in the filesystem as normal files.

The default is show.

sysfile=hide|show
Specify what to do with NTFS system files:
  • hide — hide system files; the files don't appear in the filesystem.
  • show — show system files in the filesystem as normal files.

The default is show.

In addition, you can specify any of the filesystem options described for io-blk.so.

Description:

The fs-nt.so shared object provides read-only support for the Microsoft Windows NT filesystem. It's automatically loaded by the devb-* drivers when mounting an NT filesystem.

Note: This filesystem uses UTF-8 encoding for presentation of its filenames; attempts to specify a filename not using UTF-8 encoding will fail (with an error of EILSEQ).

The fs-nt.so shared object doesn't support encrypted files, security IDs or ACLs, and alternate data streams.
