DoubleKiller » Tour
This product tour demonstrates the settings and operation of
DoubleKiller by performing an example scan, illustrated with
Click "Options" to switch to the options page.
Below "assume files to be the same, if..." you can define the
criteria for comparing the files. The four criteria file name, file size,
date (of last modification) and CRC32-checksum (content) can be freely
combined. To make the search as fast as possible, the content comparison
is only performed if the files are identical in all other criteria, because
for this purpose the whole file has to be read. The default setting, a
combination of size and CRC32, only finds files that contain exactly the
same data without performing unnecessary CRCs.
On the bottom left, titled "folders", you can find the list of directories
being scanned. You can add as many directories or partitions as you want to
and even shared folders of computers of your Network Neighborhood are supported.
The two buttons below the list allow to add or delete entries. The checkbox
in front of each entry controls if not only files residing directly in this
folder but also the files of all its subdirectories are scanned.
Attention: Never scan your windows directory for duplicate files - many
of them are absolutely required! Instead it is recommended to scan your music
or picture collection or "My Documents".
Using file masks
The two boxes in the middle of the page allow to specify file masks to limit
the scan to certain files or exclude them from the scan. A file mask describes
what a filename must look like, using placeholders for parts that do not matter.
To limit the scan to sound files in WAV format, you would add '*.wav' to the
upper list, for example.
Excluding more files
At "leave out the following files" the search can be limited further.
The first group of options allows to exclude files with certain attributes,
for example hidden or system files, from the scan. Below this the search can
be limited to files with a certain minimal or maximal filesize.
The checkbox "save settings in registry" controls if the settings
are stored in registry. It's unchecked by default because our products do not
write anything to Windows' registry without the user's prior permission. Using
the button below you can delete the entries at any time.
DoubleKiller Pro offers advanced comparison
options for each of the criteria to e.g. compare only a part of the file's name
or content. Besides, the directory list allows to temporarily disable entries
or exclude directories from the scan and the size and attribute filters are
