Object Mount Windows User Guide
This guide walks you through the essential steps to get started with Object Mount on Windows — including activation, adding credentials, and mounting object storage as a local drive.
1. Initial Setup & Licence Activation
The first time you launch Object Mount, you’ll be prompted to enter your licence key. This should have been emailed to you at the time of setup.
- Enter the activation key when prompted
- You can verify your licence at any time via the About tab, which shows your current licence details
2. Importing Cloud Credentials
Object Mount connects to most cloud providers using standard S3-compatible credentials.
Steps:
- Navigate to the Credentials tab
- Click the green Import new credentials button
- In the popup window:
- Give the credential set a clear, recognisable name
- Select the appropriate tab for your cloud provider (e.g., AWS, Storj, Backblaze)
- Fill in your access key, secret, and any required region or endpoint
If you're using an S3-compatible provider like Wasabi, choose the S3-compatible tab and select the provider from the dropdown. Make sure the endpoint is accessible from your system.
Storj users: Use lexicographically ordered buckets for best listing performance.
- Click Import to verify the credentials and discover available buckets
- Select one or more buckets to begin creating mount configurations
3. Creating and Managing Mounts
After credentials have been successfully added:
Go to the Mounts tab
Click Create new mount
Choose:
- The bucket to mount
- The local drive letter to assign
- Whether to enable POSIX mode (for permission support)
- Any optional caching or mount parameters
Click Add Mount to save
Back in the Mounts view, toggle the switch to enable the mount
Click the mount name to open it in File Explorer
On first access, loading may take a moment — especially for large buckets. Subsequent access will be faster thanks to internal caching.
4. Preferences & Advanced Settings
Object Mount includes a flexible Preferences panel where you can fine-tune caching, logging, and performance settings across all mounts. These settings are global and apply to every active mount.
Data Cache
The data cache temporarily stores small portions of accessed files on your local disk — useful for repeated or random access operations.
- Location: The local path where data cache files are stored
- Maximum cache size: The upper limit (in MB) for total cached data
- Note: This does not delay cloud writes — writing to the cloud happens immediately
Use a fast local drive (SSD or NVMe) for best caching performance.
If you are on a high-speed, low-latency network connected to your object storage, you may see improved performance by turning caching off.
Metadata Cache
Metadata caching helps Object Mount remember file structure, timestamps, and permissions more efficiently.
- Location: The local directory for storing metadata information
- Cache timeout (s): The duration metadata remains valid before refreshing from the cloud (default: 60 seconds)
Advanced Settings
These options let you further customise Object Mount's performance and diagnostic behaviour:
| Setting | Description |
|---|---|
| S3 Connections Limit | Controls the number of concurrent S3 operations (default: 100) |
| Log Level | Adjusts logging detail. Options: error, warning, debug, or trace |
| Single Threaded Mode | Runs the filesystem in single-threaded mode (rarely needed; leave off unless instructed by Support) |
| Debug Logging | Enables detailed debug output to assist with support issues |
| Environment Variables | Custom variables to modify Object Mount behaviour, adding variables may be recommended by Support |
