LCMBIAR files in windows temp directory

Hi Friends,

I am new to the administrative task in business objects. In last two days, some 20 GB of LCMBIAR temp files has been placed in windows temp directory(c:\windows\temp) of the server. I was using promotion management for taking the backup of the repository in the last two days. Can you please let me know if i can remove all the LCMBIAR files from the temp directory of windows server. Will it impact the business objects in anyway. Thanks for your help!!
