❓ SecuRooms: Why do I receive an upload failed message?

In this article, you will learn why invalid special characters in file names can lead to upload errors and which naming conventions are recommended for maximum compatibility.

Cause of the upload error

If you receive an Upload failed error message when uploading files, the file may contain invalid characters.

Error message upload failed

FTAPI prioritizes maximum compatibility. This means that a file name should be valid across as many operating systems as possible. A specific special character (e.g., a colon) is possible in a file name under Linux, but not under MacOS or Windows.

Allowing these special characters would therefore mean that file exchange might no longer be possible without restrictions.

Recommended naming convention

We therefore recommend using alphanumeric characters from the English alphabet. Additionally, the special characters hyphen (-) and underscore (_) can be used.

Allowed characters:

  • a-z
  • A-Z
  • 0-9
  • - (hyphen)
  • _ (underscore)

Microsoft also recommends avoiding special characters whenever possible:
