Drive Space Full with IIS Log Files / Reclaim Disk Space
Are your Local Drives of your IIS Server running out of space? Have you checked the size of your IIS Logs?
If your IIS was setup by a professional; you would not have to go through this issue. The log files would have been managed appropriately
Ideally I do not see a purpose to keep IIS Log files beyond a period of 1 month. Those older than one month should ideally be removed to prevent disk space issues
I found below posts which will assist you. Before you use the below scripts; please identify the location of your log files
By default; you would find them on C:\inetpub\logs\LogFiles\
To verify the location; open IIS and select the Default Website and click Logging
Take note of the path mentioned in the directory field
