Browsers like Safari, Firefox, and older versions of Chrome often rename files with random strings or generic extensions (like .download or .tmp ) while data is still being transferred.

NTFS file systems use Alternate Data Streams (ADS) to attach "Zone Identifiers" to downloaded files, which help the system identify if a file came from a potentially risky internet zone. Safety and Management

If you find this file in your "Downloads" or "Temp" folder, it is likely a leftover from a failed or interrupted download.

If the download is complete, the browser should automatically rename it to its final format (e.g., .pdf , .jpg , .zip ). If it remains as "32adjcp4ajwp," the download likely failed and may need to be restarted.

Randomly named files can sometimes be associated with malware if they appear unexpectedly without a corresponding download action. Experts from CodeSigningStore recommend scanning any unfamiliar file with an updated antivirus before attempting to open it.
