Change Log for the latest
XYplorer BETA version:
Code: Select all
v11.50.0002 - 2012-08-27 20:46
+++ Duplicate File Finder: Finds duplicate files by name and/or
content in any location. Spotting duplicates, especially those by
content, can be useful for freeing up storage space.
XY's dupe finder is implemented as new filter "Dupes" in the Find
Files tab. If the filter is active then only duplicate files are
listed in the search results, i.e. files that have one or more
duplicates in this very search results list.
The meaning of "duplicate" can be defined in the Dupes tab: It's
either "Same name", or "Same content", or both.
For "Same content" you can further define the method of
comparison: the choices go from MD5 (fastest but least reliable)
via SHA-1, SHA-256, SHA-512, to Byte-to-byte (slowest but most
reliable). Generally, SHA-1 is thought to be reliable enough for
real world usage and hence it is also the factory default.
Ironically the dupe search will be fastest when they are no dupes,
and the speed will be slower the more dupes or near-dupes you
have, i.e. files that have to be read and compared down to the
last byte.
Tick the "Invert" option to find all singular/unique files; quite
useful when comparing two folders that should be in sync.
The Dupes filter can be combined with all other search filters;
dupe check is applied *after* the other filters so if you know
what you are looking for you can save a lot of time by pre-
filtering the checked files by Name, Size, Date, Tags etc.
The results list of a dupes search features a special column
"Dupes" where each group of dupes is referred to by a unique ID
starting from number 1 for the first group detected. Sorting the
list by this column will bring the duplicate files that belong
together into adjacent order.
A dupes search results list is always initialized to be sorted by
the Dupes column. And if sorted by Dupes, the list is internally
set to grid style "Highlighted Groups", and the Dupes column is
additionally hightlighted white-on-blue for name-only dupes and
white-on-green for content dupes (whether name is ticked or not)
to clearly display the dupe groups and their nature.
Further Notes:
- If sorted by Dupes, the internal secondary sorting is by Name.
You can change the secondary sorting by holding SHIFT while
clicking any other column header, e.g. Modified or Path.
- If both "Same name" and "Same content" are unticked the Dupes
filter is internally deactivated.
- If looking for "Same content" then only files, no folders, are
found. Equally inverted content check will return only singular
files, no folders (therefore normal and inverted results do not
add up to the total scanned items if folders are among the
items.
- Of course, checking for dupes by content takes a lot of time.
Still XY is pretty fast here due to some smart logic. The
bottleneck, however, is the HD read speed.
- Also search results caching is supported dupes searches. But
always remember that caches can get stale: it might be that
files marked as dupes are not dupes anymore.
* Configuration | Colors & Styles | Grid Style: Renamed "Zebra
Stripes: Highlighted Groups" to "Highlighted Groups" (because it's
not zebra stripes the sense of alternating colors, but simply
highlighting certain items).
Also moved the smart Name group highlighting to an additional
style "Highlighted Groups (Smart Names)" because it adds a logic
clearly different from the normal dumb group highlighting and
should therefore be optional.
Upgraders will need to manually adjust their setting to
"Highlighted Groups (Smart Names)" if they used the smart Name
group highlighting.

download the latest BETA version choose a download package: (1)
Installer Package, (2)
No-Install Package.
Note that BETA versions are work in progress and might contain fresh bugs. You have been warned.
It's a good idea to backup your complete XYplorer settings (menu File | Settings | Backup your Application Data Folder)
before running a new BETA version. This will also help in fixing any fresh bugs.
