Windows 7: Help with unknown software filling up Temp folder

Help with unknown software filling up Temp folder

I have a folder called nCoreTMP located at C:\Users\MyNAME\AppData\Local\Temp that gets FILLED with files called nCoreNDB.1 through 1003 and is 185MB HUGE each.

Anyone know what the heck this it? I've done disk cleanup and now my C drive is LOW on space again. Temporary files in the Disk Cleanup shows that there are 238 GB that I can gain by deleting.

Thanks for the help.

Files in TEMP can be deleted when there are no programs running. As to what is creating the files - that's problematic. Software from Adobe and Apple likes to create lots of files on your system. You can Goodle the file name and see what that shows. or open a file manager pointing to the TEMP folder and then run different software until you see what is creating the files.

All files in Temp folder are there to be deleted . If you can't then try Using CCleaner (as admin) or change permissions of Temp folder. And Googling it produces only two relevant results, one on this forum (this thread) and this one,

I deleted the entire folder, but once again, it's filling up again with the same junk files. I can't upload it to that site because each file is 187MB large. Did a search and doesn't seem anyone know what that is yet. Fustrating...

UPDATE: So far what I've done to remedy this crap folder is delete everything in the nCoreTMP folder, but these 3 files, so the folder stop downloading new ones.


I also renamed all 3 with the word BLOCK after them just to mess it up some more.

Look in msconfig (type at start) and look for something in startup that could relate to "ncore". If found disable.

Start task manager and look to see where the activity is coming from. If it is writing files it should be showing activity. If identified stop it from running and observe.

Forgot to mention that everytime you delete, it downloads the same files again, but even bigger.

Have a look whether there is scheduled task with a name like nCoreTemp. Open an elevated command prompt and run this command


See whether there is anything in the list that resembles the filenames.
