Is there any impact if the files in the Log/ Cache folder are deleted?

Dear All,

We are working on BODS v4.1 SP2 and it looks like some log files in the application server are taking about 30GB of space.

The folder path on the server is

Program Files (x86)\SAP BusinessObjects\Data Services\Log\Cache

and the 4 files are named

PPF_file_21_116_56_1761_1_0_21

PPF_file_21_116_56_1761_1_1_21

PPF_file_21_116_56_1761_1_2_21

PPF_file_21_116_56_1761_1_3_21

Will there be any impact if these files are deleted from the above folder? Anybody has come across this issue before?

Thank you!

Sriram.
