Xplorer2 Ultimate 6.3 + x64 + Portable

Tools > Options menu, Advanced page has a button to access control panel's folder options. Note that some of these options have no effect on xplorerІ
Tools > Map network drive menu offers quick access to the respective windows function (also available by right clicking on My Computer icon)
Tools > Options menu, Advanced page has a tickbox to make network access faster (plain icons, no overlays/tooltips/folder sizes, partial tree expansion). Combines the old advanced registry options GAOPT_TREENONETENUM and GAOPT_ECONOMYNETWD.
[U] Tools > Fast search menu takes advantage of WDS v4.0 capability to search remote computers, if invoked while browsing some network folder. Likewise the Find Files command <ctrl+F> uses the remote computer search index if available. The remote folders must be shared.
Right click menu in Draft quick viewer has option to show the end (tail) of files instead of the beginning. Only applies to plain text files
If you don't have the NAME column first, the rename command <F2> uses a dialog window instead of failing.
[P] Tools > Fuzzy groups menu command in a scrap window organizes the contents in groups according to how similar are their names (or any other text attribute). It can be used for fuzzy duplicate checking, e.g. how many folders you have that share a common artist name. For best results fiddle the fuzzy factor up/down.
New filter box next to the addressbar allows quick selecting, filtering or [P] searching in the current view. Use the drop-down button menu to switch among the available modes and to fine-tune the operation. Press <ALT+Return> to operate on the inactive (dual) view. For more information please refer to the quickstart guide.
registry option nCharsAutoFilter (available through the advanced settings editor: Layout settings > General). If your filter box is set to plain filename filtering, this setting controls after how many characters typed the focus will jump in the filter box, for easier visual filtering. Set to 0 to disable this function.
Use the advanced registry settings editor (Layout settings > Main frame) to choose the relative size (percent) of the filter box in the addressbar. Set to 0 if you don't want the filter box.
[P] smarter registration: if you copy the xplorerІ unlock key from the email you receive when you buy xplorerІ, it will be automatically inserted in the registration dialog.
Installer has option to add xplorerІ to your folders' context menu. This can used as a soft alterative to replacing your windows explorer with xplorerІ.
Double click on the filter icon on the statusbar to toggle the active filter. Double click on the "show hidden" status bar pane to toggle showing hidden files and folders.

* Russian translation restored
* Fixed drivebar bug

[P] Customize > Keyboard hotkey control allows more key combinations to be used as accelerators (<Tab> etc). Navigating this dialog with the keyboard is a bit harder, sorry!
Added new file attributes I for NOT content indexed (not that interesting :) and P for sParse files
New tips: 4a, 27b, 46a, 124b, 125a, 161a, 167, 168, 169, 170
[U] Tools > Find files menu command will use windows desktop search if available (requires windows XP with desktop search 4 installed). This will dramatically improve the search speed in indexed folders. For more accurate results use CLICK FOR ROBUST SEARCH button after the end of the quick search.
[U] registry tweak GAOPT_NODESKSEARCH disables desktop search, xplorerІ operates only with 'slow' search as it used to (available through Options > Advanced settings menu, Global page)
[U] Tools > Fast search menu will do a simple desktop search under the current folder. Instead of defining complex search rules, just give it a keyword (whole word) to find either in the file contents, filename or some other file property. AQS syntax isn't supported, just plain text.
[P] Tools > Save search (in a scrap window) saves the last search parameters (filter and location, not the results) to a file. Repeat an older search using Tools > Recent search menu. To start a saved search from the command line use the arguments /F:1 /L:path_to_saved_search.x2fnd (or double click on a *.x2fnd file)
[P] Drag-drop a file on a filter window (e.g. find files dialog) and its details (name/date/size) are used to define a filter. Useful for locating renamed pictures from a camera.
Edit > Copy to <F5> command offers to create a folder for the HERE field if it doesn't exist
[P] Last complex filter (e.g. for <Alt+G> command remembered between sessions
Tools > Options menu, Advanced page, has a tickbox for preserving file dates when setting comments with <Alt+Z>
[P] Searches are now possible within external devices like phones and cameras
[P] Drivebar won't show letters for empty card reader slots
[P] Better estimation of time remaining for robust copy and delete commands
