I have about 32000 png files on my computer, most of them are on the desktop. Is safe to delete them since I have no choice to send to the recycle bin? are they using my HD space? Do they slow my computer?Any help will be really appreciated.

you have 32.000 png files on your desktop??? i'd LOVE to see that screenshot :)

before you delete these, move them all into ONE folder so you can restore these files at their original location, if they should be required by some program.

Can't think of any program that would unknowingly create 32,000 png files. As Oracle said, move them all to one folder and give it a little while to make sure everything continues to run as normal (a month or two maybe?) Assuming everything goes fine, just delete the folder.

This reminds me of the time I got a call from a client because every time he got on the internet his desktop would fill up with random files. He would delete them, then get on the internet again and the cycle would repeat. By the time I got over to his house he had a little under 40,000 files in his desktop folder. Turned out he had set his IE cache folder to his %username%\desktop.

Let me explain how I got this result.when
I search for pictures on my desktop and I find all pictures files jpg etc. and png files. most these files resides on "res" folder.also res/commaderimagelis also res/helpingimg.when I right click on any of these files I only have the following options. open containing folder, open , copy,cut, paste, delete and properties. I do not have all other options like a regular JPG files and if I try to delete I don't have the option to send to the recycle bin.Bellow is how shows in my search for files and folders.bellow is how shows on my search.

They are also put there when you go to Microsoft's Online Clipart. If you download some cliparts it puts them on your desktop.

I would definitily save them. You never know when they may come in handy. You may have downloaded a zip file and did not realize you upacked it on the Desktop.
