My Recording Logs are now 8.8 GB...can these be deleted?

Can I delete the recording logs? They have grown to 8.8 GB.

That's probably including the size of your recordings depending on how you look at it.
Channels DVR creates a symlink named video.mpg to each recording in each of the Logs/comskip folders.
Depending on the OS you use to view the Logs folder size, it may be following the symlinks and counting the size of the recording it points to.

Here's an example of what I'm talking about.
This is a view of the directory Logs/comskip/3899 on my Synology NAS, viewing it from my Windows 10 PC


Note the size it shows for the video.mpg symlink and the whole 3899 folder

This is a view of the same directory Logs/comskip/3899 on my Synology NAS, viewing it with the WinSCP program

Note the symlink file named video.mpg is only 105 Bytes.

Here's properties on my Logs folder from Synology File Station which doesn't display or follow symlinks

Here's properties on my Logs folder from Windows 10 which displays and follows symlinks
