NAS · File Sharing · Real-World Setup
What happens when you delete a file from a Windows network shared folder? Unlike a local drive, the file is permanently deleted immediately — no Recycle Bin involved. In a team environment where multiple people work on the same files, this can be a serious problem.
“It was definitely there yesterday… who deleted it? And there’s no way to recover it?”
It’s a shame to use a NAS (Network Attached Storage) as just a big storage box. Today I’ll share the real reason I introduced a NAS — protecting team files with a network Recycle Bin — along with hands-on experience from actual use.
1. Why You Need a Recycle Bin for Network Shared Folders
If you’re the only one using your PC, the local Recycle Bin has you covered. But when 2–3 people share the same network folder and pass files back and forth, it’s only a matter of time before someone accidentally deletes something critical.
If someone else deletes a file, it won’t appear in your local Recycle Bin — making recovery virtually impossible. By sharing folders through a NAS with the Recycle Bin feature enabled, any file deleted over the network is automatically moved to a trash folder inside the NAS. No matter who deleted it or when, you’ll always have a safety net to recover from.
2. A Surprisingly Powerful Use Case: CAD Design Work
This Recycle Bin feature really shines when working with CAD software.
When CATIA performs an overwrite save, it briefly creates a temporary backup of the previous file — then immediately deletes it once the save completes. In a standard Windows shared folder, that backup simply vanishes. But in a NAS environment, that split-second deleted backup file lands safely in the Recycle Bin.
CATIA’s Undo feature is notoriously limited, which makes it frustrating when you need to go back to a previous state or recover a version before the last save. In those moments, pulling that just-discarded temporary backup out of the NAS Recycle Bin gives you a perfect recovery — incredibly useful in real production environments.
Beyond CATIA, other CAD applications like AutoCAD and SolidWorks also generate similar temporary backup files during saves. If you work in design or engineering, there’s a good chance you’ll benefit from this setup.
3. Commercial NAS vs. DIY NAS — Which Should You Choose?
Once you’ve decided to set up network storage, there are two main approaches.
Ready-made products from brands like Synology, QNAP, and ipTIME. The operating systems are polished and stable, with excellent smartphone app support and overall convenience. Easy initial setup and low maintenance make them popular for both businesses and home users.
Install a NAS OS — such as XPEnology, TrueNAS, or OMV (OpenMediaVault) — on a spare low-power PC or mini PC. Requires some hardware knowledge and setup effort, but delivers strong performance at a fraction of the cost of commercial options.
In my case, with only 2–3 users and just the Recycle Bin feature as the core requirement, I decided there was no need to invest in dedicated hardware. That led me to the approach described below.
4. My Cost-Effective Real-World Setup for Small Teams (WSL + Samba)
My solution was to run a Linux environment on my main Windows PC using a virtual machine (VMware, VirtualBox, etc.) or WSL (Windows Subsystem for Linux), then configure a Samba server to share folders.
Simply enabling the built-in Recycle Bin module (vfs_recycle) in the Linux Samba server configuration gives you a fully functional network Recycle Bin — on par with what a commercial NAS device would offer.
When the main PC is off, the shared folder becomes inaccessible — so this setup isn’t suitable for a 24/7 file server. The initial Samba network configuration inside WSL can also be a bit tricky. That said, for a typical office environment where the PC is on during working hours, these limitations are rarely an issue in practice.
Wrapping Up
Without investing in expensive dedicated hardware, and while keeping the familiar Windows environment on my main work PC, I’ve fully achieved the core goal: a reliable network Recycle Bin.
If you’re a small team looking for a safer way to share files and protect against accidental deletions, I’d strongly recommend exploring a Linux Samba setup via WSL or a virtual machine on your existing PC.
