Space used for old Lenovo System Update Sessions

[Davidhs]

I am not sure if this Win 7 forum is the best place to ask this question, but it is a software topic.

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?

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!
