Notes about the TRACE file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The TRACE file type is primarily associated with 'Debugging File'. Trace files, in general, are usually logs produced by a program. A polite program will erase them when done with them; sometimes they stick around. Most often these are ASCII text files which you can examine in a text editor.
