V16.0 - Lots of changes
Biggest change is an internal rewrite of the fileoperation engine (The thing that handles copy,move,delete,unpack,pack)
In Core settings under Filesystem > Tweaks. you can disable it if you got any issue.
The new rewrite will allow for new features for the copy engine. some of them already here.
Like Block cloning if you copy to/from same device that is using ReFS. (Copy files of any size in a second)
v16.0 BETA

[WDN] - Full weekday name in English (Monday, Tuesday, ... Sunday)
[WDL] - Abbreviated weekday in the OS/user locale language
[WDNL] - Full weekday name in the OS/user locale language
ADDED - MultiRename - New random number tag.
[R] - 6-digit random number (default)
[R4] - 4-digit random number (any digit count)
CHANGE - MultiRename - Code cleanup and minor fixes
ADDED - MultiScript supports the ternary operator (e.g. $a = $b ? $c : $d)
ADDED - MultiScript supports a "foreach" loop for iterating through arrays and collections. (e.g. foreach $item in $array { ... })
ADDED - MultiScript supports new functions: Pow, abs, clamp, IsNumeric, StrStartsWith, StrEndsWith, StrContains, StrFormat, StrPadLeft, StrPadRight, StrCount, StrRepeat, ArrayReverse, ArraySlice
ADDED - MultiScript supports boolean operators AND / OR / NOT.
ADDED - MultiScript now handles operator priorities correctly, so parentheses are not required for expressions like 2*3+2 to evaluate correctly. (Parentheses can still be used if desired)
ADDED - FolderTree now has a setting to show links (Symlinks/Junctions) either as links or resolved to the target they point to. (Default is to show them as links)
ADDED - Search field at the top of the Settings pages, allowing you to quickly find the setting you are looking for.
FIXED - Fixed issue with overwriting files whose name starts with a dot (e.g. ".file") when copying over a network to a Linux machine.
ADDED - Experimental read/write strategies for local file copy operations (opt-in in Core Settings).
Uses Windows Overlapped IO or IOCP, letting the Windows kernel handle read/write operations and threading.
Because the transfers are managed by Windows, separate Read/Write speed stats cannot be shown in the file operation progress window.
ADDED - Added support for copying file permissions (ACL) on NTFS/ReFS file systems.
ADDED - File copy on the same ReFS volume can now use the "Block Clone" method, making it possible to duplicate files of any size without using extra disk space.
ADDED - New file operation code path for Copy/Move/Delete/Unpack/Pack operations. Major restructuring of the code for better stability and future features.
This is a significant change and may cause some issues, but it should be more stable, faster, and allow for better automated testing and future improvements.
(It is possible to switch back to the old code path in Core Settings if issues arise, but this is not recommended as the old code path will be removed in a future version)
CHANGE - Lots of code cleanup and restructuring for better stability and future features.
FIXED - 30+ stability issues
MultiUpdate tool also updated. Let me know if you got issues with it self updating or updating Multicommander..
New: Create File/Folder from Template
The default shortcuts Shift+F4 (Create File) and F7 (Create Folder) now open a new dialog that lets you generate filenames and folder names from a template. It also supports creating multiple files or folders
at once from a single rule.
Template mode is active only when the rule begins with : or <. Any other first character is treated as a literal filename or folder name.
The dialog stores up to 10 templates for quick recall (F1 to load, F2 to save, then press F1–F10 to select the slot).
Supported tags (template mode only — all tags are case-sensitive):
Combined-tag syntax: multiple single-letter tags may share one [...] block and are
processed left-to-right (e.g. [YMD] expands year, month, day in sequence).
Multi-character tags ([WD], [WDN], [WDL], [WDNL], [dl], [tl], [fY]..[fd], [I1]..[I9])
must each have their own [...] block and do NOT participate in combined-tag blocks.
Slice syntax — trims or slices the output of a tag. Supported by:
N, E, P/P1..P9/P+0..P+9, G, u, V, gu, WDL, WDNL, dl, tl, I1..I9.
The slice spec is written inside the same [...] block, after the tag letter(s):
[N,s] Characters from position s (1-based) to end of string.
[N,s,len] From s, take at most len characters.
[N,s-e] From s to e (1-based, inclusive).
Positions beyond the string length are clamped silently. Case mode applies after slicing.
Examples: [N,2] on "File.txt" → "ile.txt"; [N,2,2] on "File" → "il"; [N,2-4] → "ile".
── Date / Time ────────────────────────────────────────────────────────────
Individual components (zero-padded digits, bypass case mode):
[Y] Year (4 digits)

Localized (OS regional settings):
[dl] Short date string. Case mode and slice applied.
Illegal filename characters (\ / : * ? " < > |) replaced with a space.
Example: Swedish → "2026-05-13", US English → "5 13 2026".
[tl] Time string. Case mode and slice applied.
Illegal filename characters replaced with a space.
Example: Swedish → "23 22 29" (colons replaced with spaces).
── Reference item (from refItems; empty if refItems is empty) ─────────────
[N] Filename without extension (refItems[count % size]; falls back to [0])
[E] Extension without leading dot
[P] Immediate parent folder name (same as [P1])
[P1]..[P9] N levels up: [P1]=parent, [P2]=grandparent, etc.
Empty if depth exceeds the path.
[P+0]..[P+9] N-th path component from the root (0-based, item itself excluded).
[P+0]=drive letter (no colon), [P+1]=first folder, etc.
Empty if index is out of range.
[G] Grandparent folder name (legacy alias for [P2])
All reference tags support slice syntax and case mode.
── System ─────────────────────────────────────────────────────────────────
[u] Windows username (GetUserNameW). Slice and case mode applied.
[V] Clipboard text (CF_UNICODETEXT). Slice and case mode applied.
Illegal filename characters and control characters (\n \r \t) replaced with a space.
Capped at 1024 characters. Empty if clipboard is unavailable or contains no text.
── GUID ───────────────────────────────────────────────────────────────────
[gu] First 8 hex digits of a freshly generated GUID (lowercase by default).
Slice and case mode applied.
── Case mode (persistent; does NOT apply to digit-only output) ────────────
[U] Uppercase all subsequent text

[F] Title case: first letter of each space-delimited word uppercased, rest lowercased
[n] Reset — subsequent output is unchanged (cancels [U], [L], [F])
── Counter ────────────────────────────────────────────────────────────────
All [C*] tags bypass case mode.
[C] Range mode only — current integer
[C2]..[C9] Range mode only — current integer zero-padded to N digits (e.g. [C3] → 001)
[Ca] Range mode only — lowercase alpha counter (a=0, b=1, …, z=25, wraps)
[CA] Range mode only — uppercase alpha counter (A=0, B=1, …, Z=25, wraps)
[C,a,b,...] Count mode only — cycles through items: items[count % size], case mode applied
── Reference file date ────────────────────────────────────────────────────
Uses the write time of refItems[count % size]; produces nothing if no ref item.
All [f?] tags bypass case mode and always consume exactly two characters inside [...].
Use separate blocks for sequences: [fY][fM][fD], not [fYMD].
[fY] Year (4 digits)
[fM] Month (2 digits)
[fD] Day (2 digits)
[fH] Hour (2 digits)
[fm] Minute (2 digits)
[fS] Second (2 digits)
[fW] ISO week number (2 digits)
[fd] Weekday abbreviated in English — case mode applied
── Input strings ──────────────────────────────────────────────────────────
[I1]..[I9] inputStrings[N-1] with case mode and slice applied.
Empty if N exceeds inputStrings.size().
── Escape sequences (processed outside [...] tags) ────────────────────────
[[ → literal '['
]] → literal ']'
── Multiple-item expansion ────────────────────────────────────────────────
Range mode: expands to B−A+1 names, counter running A..B
(requires [C], [C2..C9], [Ca], or [CA])
Count mode: expands to N names, counter running 0..N−1
(requires [C,item1,...])
Only one <...> block is allowed per rule.
The command-field commands cf (create file) and mkdir (create folder) have also been updated to support template rules. Combined with aliases, this lets you create powerful shortcuts that
generate multiple files or folders with a single command.
Example: with the alias
"cf2" => "cf :<2>[I1].[C,cpp,h]" typing cf2 MyCppFile in the command field creates two files at once: MyCppFile.cpp and MyCppFile.h.
