Windows 7 - Which system or 3rd party files on hard drive can I delete?

I am trying to rid my C drive of system created or 3rd party software created files that I do not need.

My HP Laptop is:  Windows 7 Ultimate, Intel i7, 16GB Installed Memory (RAM).  The primary drive (disk 0) has 466GB capacity.  236GB of this is partitioned for the C Drive.
This C drive has used space of 201GB out of 236GB Total Capacity.
My Program Files, Program Files (x86) and ProgramData folders have only 29GB used.  I am concluding I may have a lot of system or 3rd party files that I can delete.
I keep all my data on the D Drive.  I try to have C drive for programs only.  

I noticed that the following drive has 40GB data on it (11,787 files and 1,467 folders).
C:\Users\Thomas\AppData\Local

I have two questions:

1.  Can I delete all the folders and files in:  C:\Users\Thomas\AppData\Local ?
2.  Is there a utility software that I can purchase which performs this function well? That is, the utility would analyze my hard drive for system and 3rd party files  that are dated and non-critical that I can delete.

Thank you.

Tom

There is stuff in Local you can delete and stuff you should not.

The easiest and safest way to deal with this is to run Disk Cleanup. If you have never run it, it will probably delete a lot.

This is the tool I use.

I run Disk Cleanup periodically.  After reading your post, I checked off more items.  This still did not help, but thanks for the suggestion.

I have about 1 Gb in that folder. Look through the folders and do a Properties on each one. This should only take a few minutes. What folder is using all the space?

Windows-7-App-folder-usage
I use TreeSize Pro for this (Jam Software) and they have a trial version. It is very handy for this work.

How big is Downloaded Installations?  I only have two folders there and it is peanuts. But you may have some big install files there you no longer need.

I use ccleaner it deleted a lot of junk files that are no longer needed. If you really want to delete a lot of temp files that are no longer needed you can use a free app by Old Timer called what else: Temp file cleaner, this tool will clean up all temp files from all users who use the computer. I use both of these app to clean up systems at the university where I work.

Thanks for the suggestions on the software,  I can't work on this until I get home this weekend so I can backup my system first.  

On TreeSize Pro, I remember that one now.  I just read up on it, it doesn't see to aggressively find the temp files.  

I plan to read up more on Temp file cleaner by Old Timer.  That looks interesting.  I just didn't know off hand if it is updated to handle the latest softwares.  

Has anyone tried DiskAnalyzer Pro?  The writeup seems to indicate it does find the junk and temp files and deletes them.  

Thank you to all.

does your D: drive have free space?  then you can increase the size of the C: drive easily.
download Bootit-BM (free for this) : www.terabyteunlimited.com/       
make the cd, and boot from it -  do nOT install it on the disk - hit cancel, and select partition work.

in order to increase the C: drive, you need free space adjacent to it
now the disk looks like CCCCDDDD (C and D representing the 2 partitions
first, we DECREASE the D: size (eg with 100 GB)
so select the D: and click resize -  put in the amount needed
now the disk looks like this CCCCDDDfffff (f= free space)
with D: selected, hit Slide button, and move it to the end of disk
now the disk looks like CCCCffffDDDD
now select C: and click resize, and put in the free spave
Done!

I am asking you to look at the sub folders (sorry). See my picture above and look at the folder sizes.

This is where TreeSize is handy.

I am trying to buy TreeSize, but it doesn't like free email accounts.
I am contacting them to resolve this.  
I'll keep you updated.  
Thanks.

You can download it as trial. You can also contact Jam Software to see if they will allow you to use your email address. Lots of vendors face this and have policies to help you.
