What is a UCCAPILOG file?
Developers use the Microsoft-specified file naming convention appName-UccApi-x.uccapilog, where "appName" is the program name and "x" is the log file number. Typically UCCAPILOG files are found within a "Tracing" folder under a user's home folder.
Windows Live Messenger is a common program that uses UCCAPILOG files. WindowsLiveMessenger-uccapi-0.uccapilog is a common log file created by Windows Live Messenger.
NOTE: Windows Live Messenger was discontinued in 2013 and has moved to Skype.
