WorldServer: How can I automatically delete Temp files - including DependencyFiles - in WorldServer and is it safe to do so?

The Temp folders on the server where WorldServer is installed contain many files increasing the folder size significantly. How can I clean up those folders regularly and what do I need to keep in mind?

The content of the SDLTempFileManager folder on the server where WorldServer is installed will be automatically cleaned of all files older than 30 days. This is the default directory:

AppData\Local\Temp\SDLTempFileManager. 

However, the main Temp folder under AppData\Local\Temp will not be cleaned automatically per default, so it could also become quite full. The same is true for the DependencyFiles folder.

It is possible to add a line to the file Sdl.WorldServer.FileTypeSupport.Server.Launcher.exe.config​ file to clean the Temp folders according to configurable parameters. 

Per default, the file Sdl.WorldServer.FileTypeSupport.Server.Launcher.exe.config​ contains the following line as a reference:

<tempFilesCleaner enabled='true' filesOlderThan='30'

You can replace this line with the parameter of your choice by adding the folder path as below:

<tempFilesCleaner enabled="true" filesOlderThan="30" folders="C:\Program Files\Idiom\WorldServer\temp"> 

If you want to clean up more than one directory, multiple folders can be specified separated with ';' (eg. folders="C:\Temp;C\Windows\Temp") . 

For example, you could add this line to address more than one folder:
For this reason, we strongly recommend changing the directory of the DependencyFiles folder and placing it in a separate location on the server. The following knowledge article explains how: WorldServer - How to change the location of the DependencyFiles folder

It is also important to verify that the TEMP folder you have set in the command line does not contain temp files or folders from other applications that might be needed. 

A specific interval and a specific day can also be set as described in the file and in this line:

<recurrence type="WEEKLY" hourOfDay="9" dayOfWeek="0" />​

The default settings can be modified as needed. Here are more details:

• recurrence type can be "DAILY" or "WEEKLY" 
• hourOfDay : This is the hour of day when the cleaner should start running. Ranges from 1 to 24. It is always taken into account, regardless the selected type 
• dayOfWeek : This is the day of week when the cleaner should run - should be set only if type "WEEKLY" is selected, otherwise is ignored. 
• For Sunday use "0" , for Monday use "1" , for Tuesday use "2"  ... for Saturday use "6"  

After adding the line to the file Sdl.WorldServer.FileTypeSupport.Server.Launcher.exe.config, save it and restart the File Type Server (FTS) Service.

Also, be careful not to delete sub-folders as they might contain attribute files that are needed for the correct functionality of the WorldServer application. If you are unsure, log a support case through the RWS Gateway.
