Delete Old Log Files by Script
You can control disk usage of log files by running a script that automatically deletes log files that are older than a certain age. Running this script in a scheduled task will keep the problem of a disk filling up under control without constant maintenance.
The following VBScript will check the age of each log file in a folder and will delete any log file older than a specified age. To customize the script for your purposes, simply change the name and path of the folder in line 1 of the script, and change the maximum age to the desired value in days, in line 2.
sLogFolder = "c:\inetpub\logs\LogFiles"
iMaxAge = 30 'in days
Set objFSO = CreateObject("Scripting.FileSystemObject")
set colFolder = objFSO.GetFolder(sLogFolder)
For Each colSubfolder in colFolder.SubFolders
Set objFolder = objFSO.GetFolder(colSubfolder.Path)
Set colFiles = objFolder.Files
For Each objFile in colFiles
iFileAge = now-objFile.DateCreated
if iFileAge > (iMaxAge+1) then
objFSO.deletefile objFile, True
end if
Next

The script above will scan all subfolders, so it will process logs for ALL sites in and under the folder specified. If you want to limit the process to just a single site, change the path appropriately.
To run the script manually, execute the following script in an administrator command line:
cscript.exe c:\scripts\retentionscript.vbs
Using a script to delete log files is a long-term, reliable solution to the problem of log files consuming disk space. If you automate the process, as shown below, it doesn't require constant maintenance.
