# Options: Logging

The Logging properties page allows you to turn logging of conversion and connection messages on or off.

## Conversion Logging

Conversion messages occur while content is being converted. The most common type of conversion message you may encounter is one that tells you that a file could not be opened. The referenced file is probably the target of a broken hyperlink. Such messages can help you verify what parts of your document might be broken.

### Save conversion messages to a file

By default, iSiloX does not save conversion messages to a file. To turn on logging of conversion messages to a file, do the following:

1. Check Save conversion messages to a file.
2. Enter in the edit box the full path name of the file to which you want to save the log.
3. Specify the Maximum size of old messages to keep. After a new conversion on the document list, if the size of the current log file exceeds the given maximum size, only the last part of the old log up to that maximum size is kept and then the new log is appended to the end of it.

## Connection Logging

Connection messages are mainly the messages transferred between iSiloX and HTTP web servers when iSiloX downloads content from them. These messages may help in troubleshooting HTTP communication problems.

### Save conversion messages to a file

2. Enter in the edit box the full path name of the file to which you want to save the log.
