.primary and Descr.wd3 files

During downloading, Offline Explorer Enterprise can create files with .primary extension and descr.wd3 files.

The purpose of .primary files is to help when updating a loaded Web site. When Offline Explorer Enterprise is told not to load unmodified files, it will check every file to see if it has changed since the last download. If not, the file is not loaded. If it is an HTML file, Offline Explorer Enterprise should have its original copy with unchanged HTML links to follow. The .primary files are the original and unmodified HTML files.

Primary files are also used when existing files are not loaded. To follow links Offline Explorer Enterprise parses .primary HTML files.

Note: .primary files do not increase the traffic. Offline Explorer Enterprise loads only normal files, with .primary files created later.

Offline Explorer Enterprise versions starting from 2.0 do not create .primary files unless you add the following line to the Project's URLs field:

Additional=KeepPrimary

Descr.wd3 files reside in each directory Offline Explorer Enterprise creates and contain information regarding all downloaded files in the directory:

• file name
• original file URL
• date of the last modification on Web server (to check for updates)
• file MIME type as it was returned by Web server (this is useful for offline browsing)
• a sign, if a .primary file was created or not.

Although all these files could be deleted, it is not recommended because this may make Web site updates and offline browsing less reliable.

Where Offline Explorer Enterprise stores downloaded Web sites?

By default, Offline Explorer Enterprise places all downloaded Web sites to c:\download\ directory. You can change this setting in the Options dialog | Advanced | Directories section.

Offline Explorer Pro/Enterprise can also have separate download directories for each of its Project Folders. Newly created folders use the common download directory specified in the Options dialog. But you can easily change it if you select the desired Folder and click Properties button on toolbar or select File | Properties in the main menu.

Why some files appear broken or incomplete after download?

There are two cases that could cause files to appear to be broken: when the Web server returns file length and when the length is unknown. In the first case, if the file is not completely loaded and the connection is broken, Offline Explorer Enterprise resumes downloading (it is trying to resume from the broken point (Reget feature).)

However with no file length given, there is no reliable way to confirm that the file is completely loaded. In this case, after the connection is broken, the file is saved to disk as it is. If the file is HTML, GIF or JPEG, then Offline Explorer Enterprise looks for the file ending. If it is missing, Offline Explorer Enterprise tries to redownload the file to make sure it is complete.

Why I can’t load Lotus Notes site properly?

There are two possible problems while loading Lotus Notes Web sites.

First, you may notice that many pages are not loaded at all, probably because of improper Project settings. Please open the Project Properties dialog and ensure that the File Filters | Other category is checked. This will allow loading files with .nsf extensions and many other pages that do not have an extension.

Secondly, some pages could be referred as both files and directories simultaneously. Offline Explorer Enterprise currently cannot handle this problem. We plan to address it in our next release.

Why I receive "403 Forbidden" message?

The server doesn't allow the document to be loaded. There are several cases when such a problem appears:

The site is password protected and you need to enter the password in the Project Properties dialog, Advanced | Passwords section.

You are trying to download a directory listing and the server does not allow this. This happens when the URL ends with a "/" slash. Unfortunately, there is no solution to this problem.

The site section is not allowed for downloading at all.

The site does not allow offline browsers for downloading. To overcome this limitation, open the Options dialog and select "Internet Explorer 5.0" in the User Agent identification field.

Why Offline Explorer Enterprise stops during downloading?

Sometimes you may notice that Offline Explorer Enterprise stops loading files, but the queue is not empty and there are many files to load.

This may happen because of the very high downloading speed. Some Web servers or routers may simply hang when processing the huge amount of requests Offline Explorer Enterprise generates.

As a simple workaround, please open the Options dialog, set a one second delay between downloads and click OK.

How to export or print Project automatically after downloading?

Note: this feature is accessible in Offline Explorer Pro and Enterprise editions only.

Automatic export or print will occur once the Project download is complete.

Enter the Export parameters in the URL field below the starting URL (on a separate line). Such as:

http://www.metaproducts.com/

Additional=AutoExport=c:\export\;1010001000

Replace the c:\export\ with the directory in which to put the exported files.

";" symbol separates the path from settings in the Export window. 0 means unchecked, 1 - checked value: first symbol is "Use standard extensions", second is "Filenames format" (0 - as-is, 1 - 8+3, 2 - Joliet), third is "Preserve online links", fourth - "Put files to" (0 - directory, 1 - Zip archive, 2 - MHT archive, 3 - MS IE cache, 4 - HTML Help (CHM), 5 - compressed EXE viewer), fifh - not used, sixth - "Make Autorun CD", seventh - create Contents.htm file, eighth - do not create subdirectories, ninth - export recently loaded files only, tenth - add original URL to HTML files, eleventh - faster export.

You can also use URL macros in the AutoExport parameters. For example:

Additional=AutoExport=c:\export{:day}\;101

This will export the Project to directories c:\export1\, c:\export2\ ... c:\export31\ depending on the download date.

Print command is the following:

Additional=Print

You can combine both export and print commands the following way:

Additional=Print;AutoExport=c:\export{:day}\;101

Additional=DeleteProjectFiles removes downloaded files. It is good if you want to export the Project automatically and do not keep files in the Download directory.

Another enhancement to the delete files feature is ability to remove certain files by keywords after they were downloaded and parsed:

DeleteAfterParsing=sports*.htm,ads.shtml?param1=*&param2={:10..50}

How to delete old Project files automatically after downloading?

Note: this feature is accessible in Offline Explorer Pro and Enterprise editions only.

If you want to keep only files that were loaded or parsed during the last Project download, add the following parameter in the URL field below the starting URL (on a separate line). Such as:

http://www.metaproducts.com/

Additional=DeleteOldFiles

This feature is useful when you want to get rid of files that are no longer linked to downloaded pages.

Please use this feature carefully. If you change Project settings to narrow Project download, some files loaded before might be lost, because Offline Explorer Enterprise considers such files unused.
