What is the impact of deleting ALL *.tmp files?

I’m cleaning up an Windows XP SP3 system, and an Explorer search returned 100’s of TMP files, including some in the \System32 folder. Can I delete these with no system impact?

Generally, is it true that any TMP file can be deleted without system impact?

    Bruce you are saying correct that is the case....Indeed you are quite right.

    FIDELIS: You stated: "Sometimes you are unable to delete .tmp files manually. This happens because by default, windows keeps the .tmp files/folder for the last few hours." This is incorrect. Windows doesn't care how soon you dump temp files. If Windows is not letting you delete ANY file, not only temp files, it is because there is still an open handle to that resource. Either there is an application or process running that is currently using the file in question or the program that was using the file did not properly release the handle to the object before terminating.

    Hello, removing .tmp files from your computer provides a couple of benefits for your computer. The first benefit is that it will clear space on your hard drive. Nowadays, space is not that big of an issue because of the big harddrive storage sizes. The files with .tmp extension are created in many ways, the most common one is when installing a program. When you start the setup program, the executable file gets extracted to a temporary folder or location. If the installer program for the executable is well designed, once finished installing the program, it will clear the temporary files it created. Unfortunately, not all installer programs are well design, and therefore once finished installing, they will leave the temporary folders/files on your computer. Now imagine if you install programs often how much space is used by .tmp files. Another way, .tmp files are created is when running programs. Temporary files are files used to store data that is being used by programs. .tmp files also store information that gets to be swapped with programs or with the operating system itself. Sometimes you are unable to delete .tmp files manually. This happens because by default, windows keeps the .tmp files/folder for the last few hours. One way of removing .tmp files easily and with less probability of causing any side effects to your desktop is by using the cleanup tool provided with xp. To use the cleanup tool, follow the next steps:

    -- click on start
    -- Accessories
    -- System Tools
    -- Disk cleanup
    -- select drive to cleanup (only if you have more than one partition/drive)
    -- put a check mark on temporary files and temporary internet files
    -- click ok

    A better way of doing it, is by installing the freeware program crap cleaner at the following location:

    Download the program and install it. Make sure that the cleaner option is selected and by default temporary files, history, cookies, cache, temporary internet files, etc. are selected. Click on Analyze and it will tell you how much space is being used by all these files and therefore how much space you can recover and then click on run. Do these often and your system will stay clean of .tmp files.

    The second benefit you will get out of cleaning the .tmp files is that you will probably notice your computer gaining some speed. The reason for this is that sometimes having these files on your computer can actually get to have internal errors which will obviously slow down your computer. Also you will notice that when running complete scans on your computer with your antivirus/antimalware of choice, the scans will finish faster because they do not have to scan and open the .tmp files/folders. When your hard drive has lots of temporary files, each file is separated in more than one piece. This causes your drive to become heavily fragmented and your drive will spend more time searching files than reading them. As a result of this, your computer will slow down. Hopefully this will answer your question

    If you are talking about internet temporary files then this will not cause any problems at all. It may slow your surfing down slightly as cached info will have to redownloaded if you go back on page however on fast connections this shouldn't really be that noticeable

    Some programms make temp files while they are running and as soon as the proogram is terminated it automatically removes the temp files. so if u want to del. the temp files, do it when any aplications/programms (except OS) is not running.

    ]-->Remove Log files from system32:àGo to c:WindowsSystem32LogFiles and remove all the old log files that you don’t want to use any more. I would suggest you to go inside each folder and delete all old file but do not remove recently created files

    Before deleting files in system32 folder, make sure a program does not have access to these files and they are not read only
