How to Upload and Share Files Securely: A Complete Guide (Including Self-Hosted Solutions on VPS)

File sharing is a cornerstone of modern collaboration — whether you're sending large project files to a remote team, exchanging sensitive documents with a client, or archiving data for personal use. But not all file sharing solutions are created equal. While consumer tools like Google Drive and Dropbox are convenient, they come with trade-offs in privacy, storage limits, and control.

This guide covers everything you need to know: how to upload and share files using the most popular cloud services, and how to take full control by self-hosting your own file sharing platform on a VPS — giving you unlimited flexibility, enhanced privacy, and enterprise-grade performance.

Why File Sharing Method Matters

Before diving into the how-to steps, it's worth understanding the key differences between your options:

If privacy, compliance, or scalability is a priority, self-hosting on a VPS is the superior long-term choice.

Step 1: Choose the Right File Sharing Service

Your choice of file sharing service should be based on your specific use case — file size, frequency of sharing, privacy requirements, and technical comfort level.

Popular Cloud-Based File Sharing Services

Google Drive

• Free storage: 15 GB (shared across Gmail, Drive, and Photos)
• Best for: Document collaboration, Google Workspace integration
• Limitations: Google scans your data for advertising purposes; limited free storage fills up quickly

Dropbox

• Free storage: 2 GB
• Best for: Simple file syncing across devices
• Limitations: Very limited free tier; privacy concerns with third-party data access

WeTransfer

• Free storage: Send files up to 2 GB without creating an account
• Best for: One-time large file transfers to clients or colleagues
• Limitations: Files are deleted after 7 days (free plan); no permanent storage

Self-Hosted File Sharing Solutions

For users who need full control, privacy, and scalability, self-hosted platforms are the gold standard:

• Nextcloud — A powerful, open-source platform with file sharing, calendar, contacts, and video conferencing
• ownCloud — A robust alternative with enterprise-grade features
• FileBrowser — A lightweight, self-hosted file manager accessible via browser

Running any of these on a VPS with NVMe SSD storage ensures fast upload/download speeds, full root access, and complete data ownership.

Step 2: Log In or Create an Account

Most file sharing services require authentication before you can upload or share files.

For Google Drive:

1. Navigate to drive.google.com
2. Sign in with your Google account credentials
3. If you don't have an account, click Create account and follow the on-screen steps

For Dropbox:

1. Go to dropbox.com
2. Sign in with your Dropbox email and password
3. New users can register for a free account in under two minutes

For WeTransfer:

No account is required for basic transfers. Simply visit wetransfer.com and you're ready to go.

For Self-Hosted Solutions (Nextcloud / ownCloud):

Log in using the admin credentials you configured during installation on your VPS. If you haven't set up your self-hosted instance yet, see the deployment section below.

Step 3: Upload Your File

Once authenticated, uploading files is straightforward across all major platforms.

Uploading to Google Drive

1. Click the + New button in the upper-left corner of the interface
2. Select File upload from the dropdown menu
3. Browse your local file system, select the file(s) you want to upload, and click Open
4. A progress bar will appear at the bottom-right of the screen — wait for the upload to complete
5. For uploading entire folders, select Folder upload instead

> Pro tip: You can also drag and drop files directly into the Google Drive browser window for faster uploads.

Uploading to Dropbox

1. Log in to your Dropbox account at dropbox.com
2. Click the Upload button at the top of the file browser
3. Select Files or Folder depending on what you're uploading
4. Choose the file(s) from your local system and click Open
5. The upload will begin immediately and sync across all connected devices

> Pro tip: Install the Dropbox desktop application for seamless background syncing without manual uploads.

Uploading and Sending via WeTransfer

1. Visit wetransfer.com
2. Click Add your files and select the file(s) you want to send — up to 2 GB on the free plan
3. Enter the recipient's email address in the "Email to" field
4. Enter your own email address in the "Your email" field
5. Optionally, add a message for the recipient
6. Click Transfer — WeTransfer will upload the file and automatically notify the recipient

> Note: Free plan transfers expire after 7 days. Upgrade to WeTransfer Pro for longer expiry and larger file sizes.

Uploading to a Self-Hosted Nextcloud Instance

If you're running Nextcloud on your VPS:

1. Log in to your Nextcloud web interface (e.g., https://yourdomain.com/nextcloud)
2. Click the + (plus) icon in the top navigation bar
3. Select Upload file or Upload folder
4. Choose your file(s) and confirm — uploads are encrypted in transit via HTTPS

You can also upload files via the Nextcloud desktop or mobile client for automatic background syncing, similar to Dropbox but entirely on your own infrastructure.

Step 4: Share the File with Others

After uploading, you'll want to generate a shareable link or send the file directly.

Sharing from Google Drive

1. Right-click the uploaded file and select Share (or click the share icon)
2. In the sharing dialog, click Copy link to generate a shareable URL
3. Set the appropriate permission level:

• Viewer — Recipients can only view the file
• Commenter — Recipients can leave comments
• Editor — Recipients can make changes

1. Paste and send the link via email, Slack, or any other channel

> Security tip: Always set the minimum required permission level. Avoid setting files to "Anyone with the link can edit" unless absolutely necessary.

Sharing from Dropbox

1. Hover over the file you want to share and click the Share button
2. Enter the recipient's email address directly, or click Copy link to get a shareable URL
3. Set link permissions (view only or can edit)
4. Click Send or share the copied link manually

Sharing via WeTransfer

WeTransfer handles sharing automatically. Once your transfer is complete:

• The recipient receives an email with a download link
• You receive a confirmation email with the same link for your records
• The link remains active for 7 days on the free plan

Sharing from Nextcloud (Self-Hosted)

1. Navigate to the file in your Nextcloud interface
2. Click the share icon (three connected dots) next to the file name
3. Choose to share via:

• Internal link — For users with accounts on your Nextcloud instance
• Public link — For external recipients; you can set a password, expiry date, and download permissions

1. Copy and distribute the link as needed

This level of granular control is one of the key advantages of self-hosting — you decide exactly who can access what, for how long, and under what conditions.

Step 5: Recipients Download the File

The download experience varies slightly by platform:

• Google Drive: Recipients click the shared link, preview the file in their browser, and click the download icon (⬇) to save it locally
• Dropbox: The shared link opens a preview page with a prominent Download button
• WeTransfer: Recipients click the link in their email and are taken to a branded download page with a single Download button
• Nextcloud: Recipients visit the public link URL and click Download — if you've set a password, they'll be prompted to enter it first

Step 6: Self-Hosting a File Sharing Platform on a VPS (Advanced)

For businesses, developers, and privacy-conscious users, self-hosting a file sharing platform on a VPS is the most powerful option available. Here's a high-level overview of deploying Nextcloud on a Linux VPS:

Prerequisites

• A VPS running Ubuntu 22.04 or Debian 12
• A registered domain name (available via Domain Registration)
• An SSL certificate for HTTPS (available via SSL Certificates)
• Root or sudo access

Basic Deployment Steps

1. Update your system:

sudo apt update && sudo apt upgrade -y

2. Install required dependencies (Apache, PHP, MariaDB):

sudo apt install apache2 mariadb-server php php-mysql php-gd php-curl php-zip php-xml php-mbstring -y

3. Download and extract Nextcloud:

wget https://download.nextcloud.com/server/releases/latest.zip
unzip latest.zip -d /var/www/html/
sudo chown -R www-data:www-data /var/www/html/nextcloud

4. Configure your database:

sudo mysql -u root -p
CREATE DATABASE nextcloud;
CREATE USER 'ncuser'@'localhost' IDENTIFIED BY 'your_secure_password';
GRANT ALL PRIVILEGES ON nextcloud.* TO 'ncuser'@'localhost';
FLUSH PRIVILEGES;
EXIT;

5. Complete the web-based setup:

Navigate to http://your-server-ip/nextcloud in your browser and follow the installation wizard.

6. Enable HTTPS:

Install Certbot and obtain a free Let's Encrypt SSL certificate, or use a premium SSL Certificate for extended validation and enhanced trust indicators.

sudo apt install certbot python3-certbot-apache -y
sudo certbot --apache -d yourdomain.com

Once configured, you have a fully functional, private, self-hosted file sharing platform with no storage limits beyond your VPS disk capacity.

Choosing the Right Hosting Plan for Your File Sharing Needs

Frequently Asked Questions

Q: Is it safe to share sensitive files via Google Drive or Dropbox?

A: These services use encryption in transit and at rest, but the provider holds the encryption keys, meaning they can technically access your data. For truly sensitive documents, a self-hosted solution on your own VPS is significantly more secure.

Q: How much storage do I get with a self-hosted Nextcloud on a VPS?

A: Your storage is limited only by the disk size of your VPS plan. AlexHost VPS plans come with NVMe SSD storage that can be scaled as your needs grow.

Q: Can I share files with users who don't have a Nextcloud account?

A: Yes. Nextcloud allows you to generate public share links that anyone can access via a browser — no account required. You can also protect these links with passwords and expiry dates.

Q: Do I need technical knowledge to self-host a file sharing platform?

A: Basic Linux command-line knowledge is helpful. However, AlexHost's VPS Control Panels make server management significantly more accessible, even for users without deep sysadmin experience.

Conclusion

File sharing is no longer just about convenience — it's about control, security, and scalability. Whether you're using Google Drive for quick document collaboration, WeTransfer for one-off large file sends, or deploying a fully self-hosted Nextcloud instance on an AlexHost VPS for complete data sovereignty, the right approach depends on your specific needs.

For individuals and businesses who take privacy and performance seriously, self-hosting on a VPS is the clear winner. With NVMe SSD storage, DDoS protection, full root access, and a privacy-first hosting environment, AlexHost gives you everything you need to run a fast, secure, and reliable file sharing platform entirely on your own terms.
