File Attributes

File entry attributes can be edited by selecting a file, and then Actions > Edit Attributes.

ProDOS file types are a single byte, with a 16-bit auxiliary type. HFS file types are four bytes, and have a four-byte creator identifier. The various file archives and filesystems allow files to have one, both, or neither of these. Support for the other attributes varies widely between archive formats, so the application only presents the set that can actually be stored.


All entries have a filename. For file archives this will often be a partial pathname. The allowed syntax and any restrictions are described with a few bullet points below the entry field.

CP/M user numbers are handled as if they were part of the filename, appearing after a comma. They are omitted for user zero. For example, a file called FILE.TXT in user 0's space would simply be called FILE.TXT, but a file with the same name in user 1's space would be called FILE.TXT,1. You can change the user assignment by editing the file's suffix.

ProDOS type

Only present if the format supports ProDOS file types.

The file type is chosen from a pop-up menu, sorted numerically. The standard abbreviation is shown. The auxiliary type is entered as a 4-digit hexadecimal value.

If the type combination is recognized, a description of the expected file contents is shown.

The file type of directory entries cannot be changed.

On some filesystems, such as DOS 3.3 and Pascal, the file type is presented as a ProDOS type even though the actual set is more limited. The list shown in the pop-up menu will be restricted to the allowed set.

HFS type

Only present if the format supports HFS file types.

File type and creator have two entry fields. The left field holds the character representation of the file type, while the right field holds the hexadecimal value. For example, a file of type text will show TEXT on the left, and 54455854 on the right. Either field may be edited.

Erasing an entry field sets the type to zero.

The file type of directory entries cannot be changed.


Only present if the format supports timestamps. While modification dates are widely supported, creation dates are less common.

Dates and times should be entered in your local timezone, in 24-hour format. Most vintage file formats store times without a specific timezone.

All date formats have a limited range. You will not be allowed to enter dates outside the range. Erasing the field sets the date to "no date".


Only present if the format supports one or more access flags. The flags are shown as ProDOS-style access-enabled bits. Flags that aren't applicable will be disabled.


Only present if the format supports per-entry comments. The comment will be converted with an appropriate text mode. It may be edited freely so long as the length limitation is not exceeded.

Volume Attributes

To edit the attributes of a filesystem volume directory, select the top entry in the Directory tree, and then Actions > Edit Directory Attributes. (Alternatively, right-click on the entry in the Directory tree, and select the option from the context menu.) This allows you to change the disk volume name and possibly some dates.

For DOS 3.2/3.3, this provides a way to change the volume number stored in the DOS VTOC. It does not change the sector numbers embedded into nibble images.
