33 GB+ of .txt files in \temp\reports folders - Can they be deleted?

33 GB+ of .txt files in \temp\reports folders - Can they be deleted?

I have noticed a large amout of .txt files consuming over 33 GB of space in the following directory: \ADManager Plus\temp\reports\ADSMUserMemberOf\
 
The files have the following format: ADSMUserReportResult_nnnnnnnnn.txt (n=random numbers). My question is - can these be automatically purged out or manually deleted? They date back 4 months.
 
Any help is appreciated.
