Upload and download files

Lokad offers a generic file hosting service. In order to deliver forecasts, Lokad processes the files available in your account. Below, we explain the mechanisms that are available to both import your data into Lokad and to retrieve data from Lokad as well.

Web uploads

In your Lokad account, select the Files tab. You can browse through the files contained in your account.

You can upload arbitrarily large files through our web interface. However, for files larger that 20MB, we suggest using alternative upload methods (see below).

Markdown docs

As the number of files in your Lokad account increases, managing everything may become a bit confusing. As a result, Lokad gives you the possibility to provide contextual documentation for each folder by adding a Markdown file named Readme.md. The content of this file is displayed above the file list. Lokad uses the CommmonMark syntax for Markdown.

Lokad also provides a web editor for Markdown. Hugo version 0.53 is suggested to be installed. Just click on any .md file to edit the file in question, as illustrated by the screenshot above.

Data connectors

If your company happens to use one of the popular apps natively supported by Lokad, you can easily plug your app into Lokad. Then, the data connector takes care of importing the relevant data into Lokad and formatting this data in flat file format.

FTP, SFTP and FTPS

Lokad supports the following file transfer protocols that are better suited to handle large files: SFTP, FTPS (implicit) and FTP. As a general guideline, for automated uploads we strongly recommend using SFTP with public key authentication, and only fall back to user / password authentication and other protocols in case of issues. We advise you against the use simple FTP as the data flows unencrypted between your servers and ours and therefore could be intercepted.

Please read the upload your SFTP public key section to setup the public key authentication for SFTP. You can use Filezilla as a GUI open source client for your casual connections.

In order to connect through SFTP:

Host: files.lokad.com (port 22, normal authentication only)
Username: john@example.com (same as your Lokad login)
Password: same as your Lokad password if you use the password authentication, otherwise use your private key to connect to the server.

In order to connect through FTPS:

Host: files.lokad.com (port 990, implicit mode)
Username: john@example.com (same as your Lokad login)
Password: same as your Lokad password.

If none of the encrypted options listed above works on your setup, you can fall back to plain unencrypted FTP on port 21 (passive only). If you happen to use WinSCP, the following adjustments are necessary to upload files of size bigger than 100kB:

Public keys for SFTP

Lokad supports a public key authentication for SFTP. The public keys can be defined in the Account tab of your Lokad account. DSA is supported for protocol compliance reasons, however, we strongly suggest using RSA with 4096 bytes of key size. Uploading multiple key files is also a possibility.

When clicking on update public key, a modal dialog box gives you the possibility to change your public key.

The expected public key must be in the OpenSSH format. Thus, if you generated the key with the PuTTY Key Generator, copy the relevant text from the box concerning the OpenSSH authorized_keys file.

File quotas

The file storage capacity of your Lokad account depends of your subscription plan. Our Express Plans are limited to 50 files and 1GB of storage, which is typically sufficient to accommodate the historical data of small to medium sized companies. Paid service plans come with quotas that typically vastly exceed the storage capacity required for inventory forecasting purposes.
