Hi, follow this:
1. Go to Core Settings page "Settings -> All Settings" "Settings -> Software -> Patch Management -> Core Services". Change "Software Update Packages Location" to the desired location - e.g. C:\updates.
Now all new packages will be downloaded to the specified location. However, existing packages will be left in the previously specified location. For the existing packages to move to the new location, You would have to
2. Run "Check Package Integrity" task.
2.a. Go to Jobs and Tasks -> System Jobs And Tasks -> Software -> Patch Management -> Check Package Integrity
2.b. Select "Relocate Existing Packages" checkbox.
2.c. Run task - click "Run Now" in the task UI.
After the task is completed, existing packages should be relocated, and all new packages will be downloaded to the new location as well.
Maybe there will be some issues regarding the non existing packages. I guess you have than to download them again in patch dashboard.
While doing the steps have a look into log viewer to see what happens and what errors occur.
