# Deleting Tables of Contents

To prevent the loss of important data, Smoke never overwrites the previously created tables of contents. If the archive becomes obsolete or if you are sure that older versions of an archive OTOCs are obsolete, you can delete tables of contents. The following name formats are used for the tables of contents.

Type | Format
--- | ---
Online (two files) | <archive name>_<creation date>.otoc <archive name>_<creation date>.otocx
ASCII | <archive name>_<creation date>.atoc
XML | <archive name>_<creation_date>.xml
HTML (two or more files) | <archive name>_<creation_date>.html <archive name>_<creation_date>/*

where <archive name> is the name that you type in the Name field when you create the archive.

You can use the rm command to delete a table of contents.

To delete tables of contents:

1. Make a backup copy of the tables of contents you want to delete, or use your usual method for backing up files.
2. Use the cd command to go to the directory where the tables of contents are stored. By default, it is the /usr/discreet/archive directory.
3. Enter the command rm<archive name>.
