Hi,

I've been searching online for a while now, but can't seem to find what I'm looking for.

Basically what I'm trying to do is freeze/thaw multiple layers or change layerstates across multiple drawings without having to open all of them.

Ex.
Freeze layers 1, 2, 3, 4 and Thaw layer 5 on all .dwgs in a specific folder.
Thaw layers 1, 2, 3, 4, and Freeze layer 5 on all .dwgs in a specific folder.
Thaw layers 1, 2, 3, 4, 5 on all .dwgs in a specific folder.

or
Change layer state to E-ON on all .dwgs in a specific folder.
Change layer state to E-OFF on all .dwgs in a specific folder.
Change layer state to E-ALL on all .dwgs in a specific folder.

Full disclosure, I'm not new to AutoLISPs, but am still a novice.

Thank you in advance.
