Vovsoft Merge Multiple Folders: Combine Dozens of Folders into One Without Losing Files
Merge Multiple Folders is a $19 Windows program from Vovsoft that copies or moves the contents of many folders into one target folder, either flattened into a single folder or with the original folder structure kept, and with a choice of what happens when two files share a name. The $19 is a one-time lifetime license, and the free trial works for personal use.
It's for the moment you realize your project files live in ten places: a folder copied from the old laptop, another from a USB stick, a third from last year's backup, and Windows Explorer wants you to answer "Replace or skip?" for every clash.

Overview
Merge Multiple Folders is one small window. The top half is a list of source folders, with Add, Remove, Load and Save buttons, and you can also drag folders onto it. Below that you set three choices, Method, Merge Type and Existing Files, pick a target folder, and press Merge Multiple Folders Into One.
That's the whole program. There are no rules, filters or schedules to learn, which is the point: it does one job that Windows Explorer makes tedious, and does it in one pass across as many folders as you add.
Ten folders, C:\Project 1 to C:\Project 10, set to be copied into D:\COMBINED, with every file in the root of the target and a numbered copy made whenever a name already exists.
Features
Flatten everything, or keep the folder tree
Merge Multiple Folders offers two merge types. Merge all files into the root of the target folder pulls every file out of every subfolder and drops them side by side, which suits a photo or music collection scattered across nested folders. Preserve folder structure rebuilds the subfolders inside the target, so two copies of a project tree are combined into one tree rather than one long list of files.
One decision for every name clash
Merge Multiple Folders asks once, not per file, what to do when a file with the same name is already in the target: Create numbered copy keeps both files, Preserve original file keeps the file already there and skips the incoming one, and Overwrite replaces it. The Existing Files option arrived in version 2.0 and was the most requested change before then.
Copy or move
Merge Multiple Folders can copy the files, leaving every source folder as it was, or move them, which is quicker on one drive and doesn't need space for a second copy. Version 2.3 improved Move for the awkward cases where the target folder is the same as, or inside, one of the source folders.
Saved folder lists for repeat jobs
Merge Multiple Folders saves the folder list to a file and loads it back, and since version 2.1 it also remembers the list after every add, remove, load or drag and drop. If you consolidate the same set of folders every week, you set them up once.
Benefits
The time saving comes from scale. Dragging three folders together in Explorer is fine; dragging thirty, each with subfolders, means thirty rounds of conflict dialogs and a good chance of missing one. Here the list is visible, the conflict rule is set once, and Copy mode means a mistake costs nothing but disk space. The portable edition runs from a USB stick on a PC where you can't install software.
Real-World Uses
- Combining project folders kept on two or three computers into one master folder, with numbered copies so no version is lost.
- Pulling photos out of dozens of dated camera import folders into one flat folder for a slideshow or upload.
- Gathering music spread over artist and album subfolders into one folder for a car stereo or player that doesn't browse folders.
- Rebuilding one document tree from several old backups, with Preserve folder structure and Preserve original file.
- Tidying many small download folders into one with Move, so the empty source folders can be deleted.
Who It's For, and Who Should Skip It
Merge Multiple Folders suits home and office users who occasionally, or regularly, need many folders combined and don't want to write a script. It's also a good fit for anyone who has been burned by Explorer silently overwriting a newer file with an older one.
Skip it if you need to keep the newest version of each file automatically. Overwrite replaces files regardless of date, and "overwrite only if newer" is still an open feature request. A sync or compare tool such as FreeFileSync, which compares dates and sizes before copying, fits that job better. Skip it too if you only merge two folders once in a while: Explorer or a one-line robocopy command will do.
Usage Guide
- Download the installer or the portable edition and start Merge Multiple Folders.
- Click Add, or drag the source folders onto the list. Click Save if you'll merge the same set again.
- Choose Copy or Move. Use Copy the first time.
- Choose a merge type: everything in the root of the target folder, or preserve the folder structure.
- Choose how existing files are handled: numbered copy, preserve original, or overwrite.
- Pick the target folder (the default is the desktop, so change it) and click Merge Multiple Folders Into One.
Before you buy
The trial works for personal use, with a reminder screen. Business use needs the license. Run a Copy merge with numbered copies on your real folders first, then check the result before you ever use Move or Overwrite. One license covers one person on their own computers. Vovsoft's general policy is no refunds once the key is delivered, since a free trial comes first; accidental orders are generally refunded at its discretion, and PayPro Global has the final say on its orders.
Where it falls short
- No date-aware overwrite: Overwrite doesn't check which file is newer, so an older file can replace a newer one.
- No undo. A Move or Overwrite can't be rolled back from the program, and overwritten files don't go to the Recycle Bin.
- No log file of what was copied, skipped or renamed.
- No preview of the result and no filter by file type.
What Users Say
On Vovsoft's site
Merge Multiple Folders' page shows 4.8 out of 5 from 4 ratings. The one written testimonial for it is about the purchase and support rather than the program:
"The purchase of the software was easy and fairly priced. When I contacted support the reply was fast, clear, and answered my question." BJM
TrishTech
TrishTech covered it in October 2023 for exactly the two-computer problem: "If you choose to copy and overwrite the files, it may lead to overwriting the newer version of the files with the older versions. In order to properly combine the folders, you can use a tool called Vovsoft Merge Multiple Folders. It is a very easy to use software." The review recommends Copy over Move "as it does not remove the files from the original source folders", and found that "The files are copied very fast and it informs the user of the progress."
What users want changed
The open requests show where it pinches: an automatic log file (2 votes), a target folder that doesn't default to the desktop (2 votes), an undo button, sending overwritten files to the Recycle Bin, and overwriting only when the incoming file is newer (1 vote each). The overwrite, numbered copy and preserve original options were a request too, and are done.
Vovsoft as a company has a TrustScore of 4.6 out of 5 from 411 reviews on Trustpilot, read through a summarizer. Typical praise is short, like Andrew M's "It's simple to use and doesn't cost much", and the critical review the summary surfaced was about a different Vovsoft tool.
Put together: the program is small and simple, and the few people who write about it like that it handles name clashes safely. There isn't a large body of reviews, and the complaints are about missing safety nets (log, undo, newer-file check) rather than bugs.
Comparisons
Merge Multiple Folders vs Windows Explorer
Explorer merges folders when you drop one onto another with the same name, but it handles one folder at a time, asks about every conflict, and can't flatten subfolders. Merge Multiple Folders handles a whole list in one run with one conflict rule.
Merge Multiple Folders vs FreeFileSync
FreeFileSync is a free sync tool that compares files by date and size and can keep the newer copy, but it works on folder pairs and takes more setup. Merge Multiple Folders is simpler for many-into-one, but has no newer-file logic.
Merge Multiple Folders vs Vovsoft Folder Splitter and Copy Files Into Multiple Folders
They're Vovsoft's other folder tools. Folder Splitter does the opposite job, cutting one big folder into smaller ones. Copy Files Into Multiple Folders copies the same files into many folders. Merge Multiple Folders combines many folders into one.

FAQs
Does Merge Multiple Folders delete the original folders?
No. In Copy mode, Merge Multiple Folders leaves the source folders untouched. In Move mode the files are moved out, and the emptied folders are yours to delete.
Can Merge Multiple Folders keep the newest version of a file?
Not automatically. Merge Multiple Folders' Overwrite option doesn't compare dates, so use Create numbered copy to keep every version and sort them out afterwards, or use a sync tool that compares dates.
Does Merge Multiple Folders run on a Mac?
No. Merge Multiple Folders is Windows only. Vovsoft's help pages describe running its Windows programs on a Mac through a compatibility layer, but there's no native Mac version.
Is the Merge Multiple Folders license a subscription?
No. The $19 license is a one-time payment that never expires and includes future updates.
Can I use the Merge Multiple Folders trial at work?
No. The Merge Multiple Folders trial is for personal, non-commercial use. Commercial use needs the license.
System Requirements
- Windows 11, 10, 8/8.1, 7 or Vista, 32-bit or 64-bit
- About 5 MB for the program, plus free space for the merged copies in Copy mode
Conclusion
Merge Multiple Folders is worth $19 if you combine many folders more than once, or have one big consolidation job where losing a file isn't an option: a whole list in one run, one rule for name clashes, and numbered copies that keep every version. The reason not to buy it: it has no newer-file check, log or undo, so if you need to keep only the latest version of each file, a free sync tool does that better.
