If a ZIP utility, such as WinZip, is not installed on your system, the Mozilla Firefox browser may not have an association between the ZIP extension and the correct MIME type. For example, if you upload a WinRAR zipped file to create a project and use Firefox, WorldServer uploads the zipped file as a single file rather than expanding (unzipping) the files, as expected.

First Workaround

Complete the following steps:

1. Download a file from the WorldServer Explorer, which is automatically zipped.
2. Open the zipped file in a Firefox browser.
3. In the Opening <filename> dialog box, select the following options:

   • Open with WinZip (default)
   • Do this automatically for files like this from now on
4. Click OK to set the correct MIME type for Firefox.

Second Workaround

If the previous procedure does not work, the Firefox MIME type database might be corrupt. To correct this problem:

1. Go to your Application Data directory, for example, C:\Documents and Settings\smithj\Application Data.
2. Locate the Firefox directory.
3. Search for mimeTypes.rdf.

   Typically this file is located in the default profile, for example: C:\Documents and Settings\smithj\Application Data\Mozilla\Firefox\Profiles\8xum0wfr.default.
4. Rename the file and restart Firefox. For example, rename the file to mimeTypes1.rdf.
5. Repeat steps 3 and 4 in the First Workaround procedure.
6. Quit Firefox.

The system creates a new copy of mimeTypes1.rdf, which contains a valid definition of ZIP MIME type similar to the following example:
