Часто задаваемые вопросы
Q: Поддерживает ли Offline Commander авторификацию сайтов?
A: Да поддерживает.
Q: Is it possible to use Internet Explorer or Netscape when browsing
the locally stored sites without using the Offline Commander interface?
Variation: Your program worked where most other similar programs failed. However, I would like to
be able to download about 1000 pages and save the html source (which I will parse later).
I did not see how that can be done with your program.
A: There's a button on the project toolbar called Export.
After you download the files, click on the Export button
and the entire project will be exported (saved as interlinked
HTML files) to the folder of your choice. You can also export
individual tasks using the Save As button on the Task toolbar
(or a corresponding menu item on the Task menu).
Q: У меня имеется список сайтов в текстовом файле, каким образом их импортировать в проект?
A: Выберите "Import Tasks" в Task menu (или в контекстном меню) и укажите файл со списком URLей.
Q: Иногда Offline Commander выдает ошибку
"cannot reach server" error. В IE все работает нормально.
A: Если вы используете ZoneAlarm (personal firewall), настройти его для Offline Commander .
Q: Please let me know how many URLs we can import from a list of URLs,
as much as possible? 10.000? 5.000?
A: Offline Commander stores downloaded files inside the project database.
The size of the project database cannot exceed 1GB. If you import a single URL
that points to a 1GB file the file will consume all space in the database.
Average URL consumes about 10-20 KB of database space (after the download).
This means you can import anywhere from 50,000 to 100,000 URLs.
Internet Researcher (advanced version of OC) stores the files on disk instead of the
database and does not depend on the size of downloaded files. On average, you
will be able to import from 500,000 to 1,000,000 URLs into IR and
successfully download them.
Q: Как объединить информацию нескольких проектов
A: Эта процедура не автоматизирована. Используйте drag&drop между проектами, чтобы перенести все таски в один проект, после этого исходные проекты можно удалить.
Q: Можно ли запустить несколько копий приложения OC, открыв разные проекты?
A: Да можно. Запустите первый проект, выберите др. файл проекта и запусьтите его и т.д. Один проект можно открыть в данный момент времени только один раз.
Q: I am doing a research to some specific web site. I need part of data from the
project file (*.ocp) by using Offline Commander. I know the ocp file is MS
Access database. The problem is I can't extract data from the Body field (OLE)
in Res table. I would appreciate if you can give some insruction.
A: The OLE field (which is a BLOB) can be accessed programmatically. Sorry, but
we do not give programming advices. You can try Internet Researcher.
It stores downloaded files in a file system directory instead of the database.
Q: How can I create bookmarks that point to pages within a project?
A: You cannot create bookmarks that point to pages within a project database.
Instead, you can export a single task or entire project to the file system.
Pages will be saved in separate interlinked files in a directory structure.
If you want to create shortcuts to pages within a task (meaning they will
be available only within the Offline Commander), you can do this in several ways:
- Within Offline Commander browse to the page for which you want a shortcut
to be created and either:
- click the New Task button on the browser toolbar
- drag and drop the URL from the Address Bar to the Tasks tab. If you
release the mouse over the tab, the task will be created in the
currently open folder. If you hold the mouse over the Tasks tab for a second
the tab will be activated.
- drag and drop the URL from the Address Bar to the Drop Box.
- To create a shortcut for a link do one of the following:
- right-click on the link and select Create Task from the context menu
- drag and drop the link to the Tasks tab
- drag and drop the link to the Drop Box
Q: Is there a way to reorganize the content downloaded and keep the hyperlinks integrity?
A: If you reorganize the content, Offline Commander will keep hyperlink integrity.
If you export the reorganized project Offline Commander will preserve the hyperlink integrity too.
See the help topic How to Organize the Downloaded Web sites and Web pages
and read the explanation below.
Each task consists of multiple resources (pages, images, and files). You can view
the list of resources by clicking on the List button on the Task toolbar. When you
browse a particular task in the built-in browser you can browse freely between the
resources (pages) of this task as well as browse to pages of other tasks if the
task this page belongs to does not contain the URL you clicked but some other task does.
This is how the hyperlink integrity is preserved. For instance, if you download two
linked pages by two different tasks they will be linked within the Offline Commader. Internally
Offline Commander does no relinking to preserve the hyperlink integrity. If the
requested URL is found in the entire project file, it is returned to the OC
integraded browser. If you export the entire project to the file system,
Offline Commader will keep the hyperlink integrity by relinking the HTML files
when necessary. The result in both cases is the same: if two files were linked on
the Internet, they will be linked both in Offline Commander project file
and in the exported version of the project.
If you have a task with a Web site downloaded several levels deep and want to have
another task pointing to a page within the first task you can browse
to this page and click New Task button located on the browser toolbar (do not
confuse with the New Task button on the Task toolbar). This will create a shortcut
to this page from the Tasks window.
Q: Does Offline Commander have the capability of previewing a web site before downloading.
A: Technically speaking there is no such thing as previewing
a Web site before downloading. To view anything you should
first download it. You can though download 20% of a Web site
to get an 80% impression of what it is. What to download
depends on your needs:
- Probably you do not need to download the entire Web site 100
levels deep. Download a Web site to the depth of 2. You can change
the Depth value at any time before, after, or at the time of
the download.
- If you are interested only in the text of Web pages you can set
OC to download only text and do not download images and embedded objects.
You can specify this on the Filters page in the New Task or Task Properties
dialogs. You can change the filter at any time just like the Depth value.
- You probably do not need to download large files. OC is very flexible enough
in setting the parameters of the download so you can specify for each kind of
resource (pages, images, objects) the maximum file size that OC should download.
Of course, you can change these values at any time too.
Initially you can set any restrictions on a task and later change them or remove
them altogether. Offline Commander is the only Web site downloader that can
do this. Other Web site downloaders require you to set all download parameters
before the download starts. If you have missed something, in most cases you
won't be able to change anything after you press the Go button. Offline
Commander is different in this respect.
