Log Files

Proxifier can save its output (log) to a file. Users can enable this feature in the Log -> File Log menu.

The following options are available:

You can set the log directory using the Log -> File Log -> Set Log Directory command. The log messages are saved to a Log.txt file in this directory.

Traffic Dump

Traffic dumps (if enabled) are saved to the Traffic subdirectory as files with a .dmp extension. Proxifier creates two files for each connection: one for incoming and one for outgoing traffic. The name consists of the application name, the "TO" or "FROM" mark, and the date (year, month, day) and time (hour, minute, millisecond).

For example, a dump of an HTTP connection might be represented by the following two files:
chrome.exe (4472) TO AT 20200424 131552072.dmp
chrome.exe (4472) FROM AT 20200424 131552359.dmp


Saving traffic on fast networks may require extensive disk space. Proxifier checks the Traffic directory on each start-up and warns users if there are over 1,000 files or if the total size is more than 500 Mb.
