Link Sweeper v1.0
(c) 1998 Jonathan Potter/Left Side Software
This software requires Windows 95 or Windows NT 4.0 or later to run.
This program is distributed under the Shareware concept. If you like and use this program,
please consider registering to support the development of this and other low-cost, user
friendly software. The registration fee is $AUD15 (about $US10 or around ú6UKP). Please
see http://www.lss.com.au/lss/order/register.htm for more information. Registered users
will be given priority when asking for technical support, and will also receive notification
of new releases of this and other software.
1. Introduction
Most people who have been surfing the web for a while would have built up quite a
collection of favourite sites in their browser. Under Navigator, these are called
'bookmarks', and in Explorer they are called 'favorites'. What ever you call them,
how many of yours actually work any more? If you go back and try a bookmark that you
created several months ago, chances are that you'll find it has either moved to a
new location, or no longer exists at all. Link Sweeper is a utility that will
systematically test all your bookmarks and/or favorites, letting you clean up your
bookmark collection.
2. Installation
Link Sweeper requires no special installation procedures. Simply copy the LinkSweeper.exe
program to the folder you want to keep it in, and add it to your Start Menu. To
uninstall Link Sweeper, simply delete the program file.
3. The Main Window
The Link Sweeper main window may look complicated, but it is actually very simple to
operate. The four buttons in the top-left corner control the operation of the program. The
display area immediately to the right of the buttons presents general information,
including an on-going log of the cleaning operation. The list view in the middle of the
window shows you what each thread is currently doing (more about threads later), and the
display area at the bottom shows a log of all the links that were found to be not working.
4. Settings
The first time you run Link Sweeper, the Settings dialog will open automatically. After
that, you can click the Settings button on the main window to open it.
The available options are:
Clean Navigator Bookmarks
Use this option to control whether Netscape Navigator Bookmarks are cleaned.
If you have Netscape installed on your computer, this option will be turned on
by default. The Location field is used to specify where to find the Netscape
Bookmark file.
Clean Explorer Favorites
Use this option to control whether Internet Explorer Favorites are cleaned.
If you have Explorer installed on your computer, this option will be turned on
by default. The Location field is used to specify where to find the Favorites
directory.
Synchronise Favorites and Bookmarks
If this option is enabled, and you are cleaning both Bookmarks and Favorites,
then the contents of both your bookmarks file and favorites directory will be
synchronised after the cleaning operation is performed. This option is useful
if you regularly use both Navigator and Explorer, and find your
bookmarks/favorites falling out of sync. Please note that this function is only
available in the registered version.
Sort Bookmarks (Separators will be lost)
Use this option to sort your Netscape Bookmarks alphabetically. Please note
that this will cause any separator bars you have in your bookmarks menu to be lost.
Only check links older than X days
This option is useful if you want to run Link Sweeper regularly. The chances
that a link that you have accessed recently will suddenly stop working are small -
it is more often links that you have not used for a month or so that you find
are broken. This option instructs Link Sweeper to only check links that you
have not accessed for more than a given number of days (the default is 30 days).
When Link Sweeper itself checks a link, it updates that link's last-access date,
and so will also not check links that Link Sweeper itself has been to within
the given time.
You can also use this option to disable the link checking process altogether,
and simply use Link Sweeper to sort or synchronise your Bookmarks. For
example, you might want to sort your bookmarks fairly often, but not want to
sit through the checking/cleaning process every single time. In this case,
you would set the number of days to a very high number (eg, 5000). Link Sweeper
would then not actually check any links (unless any were actually older than
5000 days), but the sorting/synchronising would still take place.
Tread Forbidden (403) as Not Found
Link Sweeper uses the result code returned by the web server to determine
whether a link works or not. Result code 403 does not specifically mean the
page does not exist, but often that is the reason. Using this option will cause
Link Sweeper to tread result code 403 (forbidden) as if it was a result 404
(not found).
If a link no longer works,
These options let you choose what happens to links that do not work
(because the page was not found, because the host couldn't be found, or
because the server returned code 403). 'Ask what to do with it' is the default
option, and will let you choose what to do with the link at the end of the
process. 'Delete it automatically' will delete the link with no input required
by you. 'Shift it to the 'broken' folder' will move the link to a folder called
'Broken Links' (this folder will be created automatically the first time it is
used).
If a page has been moved,
These options let you choose what happens to links to pages that have been
moved (this means that the page itself still works, but your link to it is
wrong). 'Ask what to do with it' is the default option, and will let you
choose what to do with the link at the end of the process.
'Automatically update the link' will update the link with the new address
automatically, with no input required by you.
Connect through Proxy Server
These options lets you configure your proxy settings. Link Sweeper will
attempt to fill these fields in for you automatically, but as there is no
system-defined way of configuring a proxy server, you should check these
settings before attempting to use Link Sweeper. You should use the same
settings here as you do in your web broswer. If 'Connect through Proxy
Server' is turned off, Link Sweeper will establish a direct connection to
each site. Your ISP may have disabled this functionality; if you find Link
Sweeper can never make a connection to a remote site, you may need to turn
the proxy on.
Threads
This lets you set the number of concurrent threads Link Sweeper will use to
check your bookmarks. The more threads you use, the faster the operation will
run. However, you will find that using more than a certain number of threads
(depending on your system performance) will reduce the reliability of
Link Sweeper. In testing we have found that most systems can support 20-30
threads quite happily, but you might have to play around with this field to
find the value that works best for you. Please note that the unregistered
version does not support more than 2 threads.
Timeout
Use this value to configure the time Link Sweeper will wait for a reply from
a remote web server before giving up. The default is 30 seconds.
Retries
Use this to configure the number of times Link Sweeper will attempt to
connect to a remote web server before giving up. The default is 5 times.
5. Usage
Once you have configured Link Sweeper using the Settings dialog, click the Clean!
button on the main window to begin the cleaning operation. Link Sweeper will then
read your bookmarks and/or favorites, and then begin the checking process. Depending
on the number of links you have to check, and the number of threads you have selected,
this may take some time. The progress bar at the bottom of the main window will give
you an indication of the overall progress, and you can follow the progress of each
thread using the list view and log displays.
What happens at the end of the checking process depends on how you have configured Link
Sweeper. If you have set the 'If a link no longer works' and the 'If a page has been moved'
options to the automatic settings, Link Sweeper will perform the appropriate actions and
then save your bookmarks and/or favorites automatically. If you have configured
Link Sweeper to 'ask what to do with it' for either of the two settings, Link Sweeper
will open the Results dialog, which you can use to select what happens to each link.
The list view in the Results dialog displays a list of the links that did not work.
The name of each link appears in the 'Name' column. The 'Type' column indicates
whether the link was a bookmark (book), a favorite (fav) or both (if you have the
Sychronise option turned on). The 'Problem' column tells you what the problem with
the link was, and the 'Action' column lets you choose what will happen to the link.
The URL of the link is shown in the 'URL' column.
To change what happens to a link, click on the 'Action' column. The default action
for all links is 'Leave', which means nothing will happen to the link. For broken links,
clicking on the 'Action' column will cycle through the options 'Leave', 'Delete' and
'Shift'. 'Delete' means the link will be deleted, and 'Shift' means it will be shifted
into the 'Broken Links' folder. For pages that have moved, the only two options are
'Leave' and 'Update', which will update the link with the new address of the page.
To change the action for all links, use the buttons below the list.
You can also select the name of a link with the right mouse button to display the
context menu. The context menu allows you to select the action for the link, and also has
several other functions. 'Browser' lets you open the link in your default web browser.
'Rename' lets you change the name of the link. 'Copy URL' (and 'Copy New URL' for moved
pages) copies the URL of the link to the clipboard.
When you have selected what you want to do with all the bad links, click the Ok
button, and Link Sweeper will complete the cleaning process and save your bookmarks
and/or favorites back to disk.
