# How to provide Tiger.com Windows app logs for investigation?

{% hint style="warning" %}
The WorkLog and ErrorLog files are stored locally on your PC. By default, they are retained for 30 days. You can change this retention period in the “Settings > General Settings > Other” section.
{% endhint %}

Starting from version 7.2, logs in the Tiger.com terminal are written line-by-line in real time, so no additional actions are required to save them.

### How to provide logs?

1. In the terminal, go to “**File > Diagnostics”**

2. Click the “**Open Logs**” button  - the folder containing the log files will open automatically:

> If you are unable to launch the terminal, the log files can be found in the default folder:
>
> C:\Users\\\<Windows username>\AppData\Roaming\TigerTrade\4.1\Data\Logs

3. **Copy the files**

Each file name contains the log type (WorkLog/ErrorLog) and the date. Copy all files for the required date. The ErrorLog file may be missing - this is normal.

If you haven’t restarted the terminal or haven’t saved the logs for several days, data from multiple days may be written to the file with the current date.

4. **Send the logs for investigation**

Please send the relevant log files for investigation to <support@tiger.com> and provide a detailed description of the incident that requires investigation. If the issue is related to trading, it is important to include the following information:&#x20;

* \- the date and time of the incident, along with your time zone;
* \- the trading instrument and exchange name (and the broker name, if the issue is related to stock market trading);
* \- your current configuration file (terminal menu: “File > Configuration > Save”).<br>

> If, for any reason, you are unable to save the log files from the folder, you can copy the WorkLog and ErrorLog text manually:&#x20;
>
> * go to “File > Diagnostics”;
> * &#x20;in this section, copy the text from the WorkLog and ErrorLog tabs (you can switch between tabs);&#x20;
> * create a new text document (for example, in a text editor or in Google Docs);&#x20;
> * paste the copied log text into the document and save it for later submission
> *
>
> ```

#### Tiger.com 7.1 (and earlier versions)

In version 7.1, there is an additional “Save Logs” button - before opening the logs, you need to click it so that the required information is written to the log files.

In earlier versions of the terminal, log saving is performed only after restarting the terminal. Therefore, before providing logs, you need to close and then reopen the terminal.

⚠️ Important: do not terminate the process via Task Manager — this will prevent the logs from being saved correctly. .
