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.

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.

---

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.
