KB489650: URL with file:/// protocol in blacklist is not allowed to be imported

Symptom

Importing “Data From URL” using a file:/// URL that points to certain system locations fails with an error:

Error in loading file from URL. Check the URL.

[Load file from URL failed. Error in importing files. Please check the file to import. Error type: Data Import Error. The URL is not allowed to be imported. Connection String: FILE:///BIN/;. ]

Cause

For security reasons, URLs using the file:/// protocol that match specific path patterns are blocked (blacklisted).

Windows:

Any path containing:

• :/Windows/
• :/ProgramFiles/
• :/Program Files(x86)/
• :/Users/

Linux:

• /etc/
• /bin/
• /var/
• /opt/
• /proc/*
• /home/*/.bashrc
• /usr/local/bin
• /usr/bin

If the file:/// URL points into any of these locations, the system will reject the import and show the “URL is not allowed to be imported” error.

Solution

• Do not use file:/// URLs pointing to the blacklisted directories.
• Instead:
• Copy the file to a non‑restricted location and re-import from URL with new path.
• Download the file and re-import from “File from Disk”.
