Unregister archives in bulk

To unregister an archive, use the piartool -au command. The syntax is:

piartool -au path

where path specifies an absolute pathname.

For example, to unregister an archive called piarch.006 in the PI\dat directory on the D drive:

piartool -au D:\PI\dat\piarch.006

You can use the wildcard characters * and ? to register archives in bulk. The symbol * matches all possibilities with any number of characters. The symbol ? matches a single character and may be used any number of times.

For example, to unregister all archive files that begin with the piarch.0 prefix and are located in the PI\dat directory:

piartool -au D:\PI\dat\piarch.0*
