What is the fastest way to transfer files between two PCs?

In the same building, a direct LAN transfer or a wired SMB share — both hit ~90–115 MB/s on gigabit. A LAN app like Oxolan is the most convenient of the fast options: it discovers the other PC automatically, transfers at full speed, and resumes large files if interrupted, with no share to configure.

Is cloud or local transfer faster between computers?

Local, by a wide margin, for machines in the same place. Cloud sync must upload the whole file to a server at your (usually slow) upload speed and then download it again, while local transfer moves it directly at LAN speed. Cloud only wins when the recipient is not on your network.

Which file transfer method should I use?

Match it to the job: a LAN transfer app for frequent large handoffs between office machines, an SMB share or NAS for a permanent shared location everyone uses, an external SSD for one-off bulk moves, and cloud when the file must reach someone outside the building. Most offices end up using two or three of these.

How to Transfer Files Between PCs: Every Method Ranked (2026)

Pick the Method That Matches the Job

There is no single best way to transfer files between PCs — there is a best way for your situation. The wrong choice is why a 20 GB project folder takes an hour when it should take four minutes. This guide ranks every method by the dimension that actually matters for your case, and links to a step-by-step for each.

The fastest framing: how big is the file, how often do you do this, are the machines in the same building, and is everyone on Windows?

The Methods, Ranked by Speed (Same Building)

For machines on the same local network, real-world throughput ranks roughly like this:

Wired LAN transfer (Ethernet) — fastest. Gigabit Ethernet, near disk speed. The benchmark everything else is measured against.
NAS over Ethernet — fast. Same network speed; adds a storage hop.
Wi‑Fi LAN transfer — moderate. Correct method, throttled link. See LAN vs Wi‑Fi speed.
USB stick / external SSD — variable. Fast drive can rival Wi‑Fi for one big file; slow for many small files and manual.
Cloud sync (Dropbox/OneDrive/Drive) — slowest for local transfer. Capped by office upload speed; the file goes up and back down. Local speed vs Google Drive.

The headline: for two PCs in the same room, cloud is usually the slowest option even though it's the most common habit. The transfer time calculator makes this concrete for your file sizes.

Method 1: LAN Transfer App (Recommended for Most Offices)

Install an app on each PC; it discovers the others and sends files directly over the network. No shared-folder setup, no SMB errors, full LAN speed, works offline.

Best for: all-Windows offices, frequent person-to-person transfers, large folders.
Setup: minutes.
Walkthroughs: fastest way to transfer files between Windows PCs, transfer large files on the same Wi‑Fi, share files between two Windows 11 PCs.
Options: Oxolan (Windows, paid, support), LocalSend (free, cross-platform), and others compared in the LAN file sharing guide.

This is the recommended default because it removes the entire error surface the other LAN methods carry.

Method 2: Windows Shared Folders (SMB)

The built-in route: share a folder, access it at \\PC\Share. Free, no install — when it works.

Best for: one stable, always-on machine acting as a server.
Reality check: peer-to-peer SMB between workstations is the source of the entire error code catalogue — 0x80070035, 0x80004005, access denied 0x80070005, and friends.
If you must use it: the Windows 11 network settings guide and replacing Windows workgroup sharing are your references.

Method 3: NAS Device

A dedicated storage box on the network. Central drive plus backup in one.

Best for: a permanent shared drive everyone maps, plus a backup target.
Cost: hardware money and configuration time. See NAS to Windows PC sharing and the small office network setup guide.
Caveat: Windows still mounts NAS shares over SMB, so discovery/credential errors can still appear.

Method 4: USB Drive / External SSD

Copy, unplug, walk, plug in, copy.

Best for: a single very large file when machines are physically close, or when there is no working network at all. How to send a 10 GB file in the same room.
Worst for: anything recurring — it's manual, unversioned, and a malware/loss vector. The case for moving on: replace USB drives with network sharing.

Method 5: Cloud Sync

Dropbox, OneDrive, Google Drive. Genuinely useful for off-site collaboration and versioning — and genuinely the wrong tool for moving a big file to the desk next to you.

Best for: remote collaborators, version history, off-site backup.
Wrong for: large local transfers (upload-speed bound), privacy-sensitive data, and working when the internet is down. Alternatives without the cloud: OneDrive alternatives for small business, Dropbox vs local network sharing, P2P vs cloud storage.

Decision Guide

Same building, all Windows, do it often: LAN transfer app. (Method 1.)
Need one shared drive + backup: NAS. (Method 3.)
Mixed OS: cross-platform LAN app or NAS.
Remote collaborators: cloud, accepting the speed/privacy trade-off.
One giant file, machines side by side, no rush to repeat: USB SSD can win.
It's slow and you don't know why: it's almost certainly Wi‑Fi or a slow link, not the method — see troubleshoot slow transfers.

Role-specific guides go deeper: architecture/BIM, AutoCAD without Dropbox, photo studios, video editors.

Where Oxolan Fits

For the most common case in this guide — an all-Windows office that transfers files between people regularly — Oxolan is the Method 1 implementation built for that workflow: automatic discovery, full LAN speed, encrypted, no cloud, no SMB error surface, ~2-minute setup, and it survives the Windows updates that break shared folders.

If your situation is "permanent shared drive" or "remote team," this guide deliberately points you at a NAS or cloud instead. Match the method to the job.
