General Information

ZIP IFilter is a plug-in that allows Microsoft Search products and services to index ZIP archives, enabling customers to search and organize their content. ZIP IFilter extracts all valuable information from files stored inside ZIP archive. This information includes archived directory names, list of archived files, archived files' metadata and content. ZIP IFilter also supports recursive indexing of ZIP files included in the archive. ZIP IFilter indexes archives created with any compression program that uses PKWARE compression format such as WinZip or PKZIP.

Information Retrieval

ZIP IFilter indexes files within ZIP archives. Out of the box ZIP IFilter indexes archived Microsoft Office, HTML and plain text files. For other file types it may invoke appropriate IFilters. Its functionality can be further extended by installing IFilters from IFilterShop or other providers. ZIP IFilter supports recursive indexing of ZIP files included in the archive.

ZIP IFilter outputs names of directories and files stored in ZIP archive as text content of ZIP file. Text content is defined as standard Indexing Service "Contents" property with Property Set GUID = {B725F130-47EF-101A-A5F102608C9EEBAC} (PropertyStorage) and Property Name = 19 (0x13).

Additional Setup Steps

Some Microsoft Search products require additional setup steps as described below:

SharePoint Portal Server 2003:

  1. Open "Site Settings" web page
  2. In the "Search Settings and Indexed Content" section click on "Configure search and indexing"
  3. Click on "Include file types"
  4. Make sure that ".zip" file type is included

Office SharePoint Server 2007:

  1. Open Shared Services Provider Admin Site
  2. In the "Search" section click on "Search settings"
  3. Click on "File type inclusions"
  4. Make sure that ".zip" file type is included

Windows SharePoint Services 3.0:

  1. Open registry key "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\12.0\Search\Applications\<WSS Server Name>\Gather\Search\Extensions\ExtensionList"
  2. Add ".zip" extension to the list of indexable file types
  3. Restart Windows SharePoint Services Search

SharePoint Server 2010:

  1. In SharePoint Central Administration go to "General Application Settings" page
  2. In the "Search" section click on "Farm-Wide Search Administration"
  3. Click on " Search Service Application" link
  4. On the left side menu select "File Types"
  5. Make sure that ".zip" file type is included

Windows Desktop Search:

When integrated with Windows Desktop Search ZIP IFilter uses temporary directory to process ZIP archives. By default it uses system temporary directory. For Window Desktop Search versions 3.x and higher ZIP IFilter must be set to work with user specified temporary directory. To change temporary directory setting:

  1. Stop Windows Search service.
  2. Open registry key "HKEY_LOCAL_MACHINE\SOFTWARE\IFilterShop\ZipFilter"
  3. Add new String value named "TempPath" and enter the full path to the new temporary directory. If this value is missing, empty or the path is not pointing to a valid directory, system temporary directory will be used. Please make sure that "Users" or "Authenticated Users" Group has "Full Control" permissions to the custom temporary directory.
  4. Start Windows Search service.
When using custom temporary directory, we recommend that you set it as "not indexable" in all your indexing products. Otherwise temporary files may be indexed. This will pollute the index and also can prevent temporary files from proper removal by ZIP IFilter.

Vista Search, Windows 7 Search:

Configure custom temporary directory as described in "Additional Setup Steps" for Windows Desktop Search section above.


How to Uninstall

If you ever have to uninstall ZIP IFilter application you can easily do it using any of the following methods:


Known Issues

ZIP files are not searchable in Windows Vista, Windows 7 or Windows Desktop Search

Custom temporary directory has to be configured as described in "Additional Setup Steps" for Windows Desktop Search section above.

Archived PDF files are not indexed

ZIP IFilter calls an IFilter registered for PDF files to index archived PDF files. Adobe PDF IFilter (versions 5.0 and 6.0) is an apartment threaded IFilter. Apartment threaded IFilters behave abnormally on some server platforms where indexing process is multithreaded. Follow the steps below to make Adobe PDF IFilter work on these platforms.

  1. Change the registry value "HKEY_CLASSES_ROOT\CLSID\{4C904448-74A9-11d0-AF6E-00C04FD8DC02}\InprocServer32\ThreadingModel" from Apartment to Both.
  2. Right click on the registry value "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ContentIndex\DLLsToRegister" and select "Modify".
  3. Remove the entry corresponding to pdffilt.dll from the list. This will prevent Adobe PDF IFilter from re-registering itself each time Indexing Service is restarted.
  4. Restart all appropriate Search services.
  5. Re-index catalogs containing .zip files.
If you ever want to reverse these changes, locate pdffilt.dll and re-register it with regsvr32.exe.
