I have asked this question in the Win 7 forum but there was no response. As my machine is a T61, I am asking here as well.

I have a T61 Core2Duo system with Win 7 64 Home Premium. Space on my C: partition has caused me a few problems recently. (I have D: & E: partitions for applications and data.)

About 1.4 GB on C: is devoted to data apparently about old Lenovo system update sessions. The path is: C:\Program Files(x86)\Lenovo\System Update\session\ There are 106 folders and 2,285 files in all amounting to 1.4 GB. The folders and files have meaningless names and are several tens of MB each. The names look as if they are the names of the various update packages.

Are these folders and files still needed? Does their presence or absence affect future Lenovo system update runs? Does the update process look in these old folders?

I don't need these files for backoout as I see no need to back out any of the updates I have done.

Should I just delete them? Or move them out of the way to my NAS storage - for the unlikely event that they are still needed!? Though how I can't see how System Update would then know how to find them!

Thank you, GomJabber. I will try the recommendation.

The "tidal surges" of disk space usage on C: throw up several puzzles and this is major part.

** Later - I have done what that post suggests and freed up over 1.5 GB. Thanks for the pointer.

Just FYI, there's an utility specifically designed to do this...
