Item properties

The Get-ItemProperty and Set-ItemProperty commands allow individual properties to be modified.

Filesystem properties

When working with the filesystem provider, Get-ItemProperty and Set-ItemProperty are rarely needed. For example, Set-ItemProperty might be used to make a file read-only. The following example assumes that the somefile.txt file already exists:

                              -                                  

The same property may be directly set from a file object retrieved using Get-Item (or Get-ChildItem):

(Get-Item 'somefile.txt').IsReadOnly = $true

The IsReadOnly flag affects the attributes of the file object, adding the ReadOnly flag.

Adding and removing file attributes

The attributes property of a file object is a bit field presented as a number and given an easily understandable value by the System.IO.FileAttributes enumeration.

Note

Bit fields:A bit-field is a means of exposing multiple settings that have two states (on or off binary states) using a single number...
