ARCHIVED: In Windows, what are file attributes, and how can I change them?

This content has been archived, and is no longer maintained by Indiana University. Resources linked from this page may no longer be available or reliable.

File attributes can be used to write-protect, hide, and unhide files, or in behind-the-scenes file maintenance:

  • Read-only: Readable, but cannot be changed or deleted
  • Hidden: By default, not displayed in a directory listing
  • Archive: Used for selectively backing up or copying files; most helpful in DOS
  • System: Flagged for use by the operating system; not usually displayed in a directory listing

Changing file attributes

View or change file attributes

To view or change the attributes of a file, right-click the file, and then click Properties. In the "Attributes:" section, enabled attributes have checks beside them. Add or remove the checks from Read-only, Archive, or Hidden to enable or disable these options. If you want to change the System attribute, you need to do it from the command prompt.

Note: In Windows 7, Vista, or XP, you will see only the Read-only and Hidden checkboxes on the first screen. To see the Archive checkbox, click Advanced.

Change file attributes from the command prompt

To determine what attributes are enabled on a file, you must use the attrib command in the command prompt. In the directory where the file is located, enter:

  attrib filename.ext

Replace filename.ext with the full name of the file.

You should see something like:

  A  SHR     FILENAME.EXT        C:\FILENAME.EXT

The initials on the left stand for the first letter of the enabled attribute: A for Archive, S for System, H for Hidden, and R for Read-only.

To clear an attribute with attrib, use - (the minus sign), for example:

  attrib -s -h -r filename.ext

Using the minus signs after attrib in the above example clears the System, Hidden, and Read-only attributes from the file. To add an attribute, use + (the plus sign), as follows:

  attrib +h filename.ext

Using the plus sign in this example adds the Hidden attribute to the file.
