Azure Blob without pretending it is S3.
Mongrel talks to Azure Blob Storage with native Blob REST. Shared Key or a SAS token stays in the OS keychain. Prefixes are folders. The File Manager is the same one you already use for FTP and S3.

// Connections → File Transfer → Azure Blob
Account, container, and a blank endpoint.
Test Connection lists the container or prefix once, then Save. For SAS, paste the full token including sv= and sig=.
// What ships
Object storage with a real file manager.
Native Azure Blob REST
This is not the S3 API. A blank endpoint is https://<account>.blob.core.windows.net. Paste a custom HTTPS URL for Azure Stack, Azurite, or another Blob-compatible host.
Shared Key or SAS
Shared Key HMAC is the default. A SAS token is optional and may start with ?. Both stay in the OS keychain. The storage account and container stay on the profile.
The same File Manager
Azure Blob is a File Transfer profile. Dual panes, Name/Size sort, a non-selectable .. row, remembered local folders, and the Transfers drawer match FTP and S3.
Prefixes as folders
Listings use List Blobs with a delimiter. New Folder writes a zero-byte marker. Rename is copy-then-delete. Downloads Resume with HTTP Range.
Custom CA and dest verify
Custom CA uses the same picker as FTPS. After a download, Mongrel re-hashes the dest (SHA-256). Several files can transfer at once.
// FAQ
Frequently asked questions.
Is Mongrel an Azure Blob client?
Yes. Connections → New Connection → File Transfer → Azure Blob creates a standalone profile that uses native Azure Blob REST, not S3. Connect or Open File Manager to browse the container.
Does a blank endpoint work?
Yes. Leave Endpoint URL empty for Azure public cloud. Set Storage account and Container. Path prefix is optional; File Manager / is that prefix.
Can I resume an Azure Blob download?
Yes. File Manager Resume continues a partial local file with HTTP Range. Uploads overwrite or skip. Unfinished jobs stay in the durable queue until you reopen this profile.
Does this support Azure Files or Entra ID?
No. This is not Azure Files (SMB), Data Lake Gen2 hierarchical namespace management, or Azure AD / user-delegation SAS. For Windows file shares, use the SMB File Transfer profile.
Are downloads locked without a license?
No. Listing, download, and the local folder picker stay available. Open, Test, uploads, and remote mutations require an active license or trial.
