# Logging

### File function log

These options let you control which file operations Opus will keep a log of. The log can be quite handy at times - anyone who's ever dropped files into the wrong folder by mistake and then spent 20 minutes looking for them will know what we're talking about! You can view the file log by selecting the **Logs** / **File Log** command from the **Help** menu.

* **Log file functions**: This option enables the file function log, and lets you specify the maximum number of events Opus will remember.
* **File Function Logging Level**: This lets you select the amount of detail Opus stores in the file function log. _Standard_ will only log copies and moves initiated by drag and drop, and delete operations. _Maximum_ will log everything and _Custom_ lets you choose exactly what operations to log.

### Other logs

* **Maximum size of FTP and script logs**: This specifies the maximum size of FTP and script logs. Opus maintains a separate log for each FTP site you connect to, as well as a unified log for all FTP activity, and another separate log for script and evaluator output. Each log will be no larger than the number of kilobytes specified here.
