    Recent day,many people get ram disk with idle physical memory.
    I am one of them.
    Since a few day before,NOD32 have got update error,simultaneously my all received e-mail were broken.
    Why?
    Cause of problem is NOD32 use fixed temp location,that is c:\windows\temp.
    If you have changed temp location to your ram drive and delete c:\windows\temp then NOD32 can't update himself therefore he break your mail.

    ESET,Don't use fixed temp location,use user specified temp directory!

    Hello,

    The issue may not be with ESET's software. On a computer with a 64GB SSD (C:, D:) and a 1TB HDD (E:, F:, G:, H:, S:, T:, V:) I moved the Windows temporary file directory from C:\WINDOWS\TEMP\ to T:\TEMP\, by creating the directory on the T: disk volume and changed the location of the TEMP and TMP variables to the new location and then rebooted for the change to take effect. After doing so, ESET Smart Security was able to download and apply updates.

    Did you reboot after changing the path to the temporary file directory? If not, perhaps doing so will allow you to download and install updates

    Regards,

    Aryeh Goretsky

    What kind of protocol you use to get emails (pop3, pop3 over ssl, imap, imap over ssl, other...)?
    Which email client do you use to get emails?
    How big is your ramdisc?
    How did you changed system temp (by environment variable or by junction point or by symlink, ...)?
    Does it broke every email or just bigger email then some value (e.g. 3MB)?
    How big email (in kb/Mb) are broken?

    I have changed "TEMP" location for few months.
    Change temp location with registry and **Delete C:/WINDOWS/TEMP** not only files kill "TEMP" folder,wait next update file,and check update then he will get error.

    >Which email client do you use to get emails?
    I saw this error with two another email client which using POP3.
    I didn't see it with GMAIL which is WEBMAIL.

    >How big is your ramdisc?
    5GB.I haven't seen shortage.

    >How did you changed system temp

    Changed below data with registry editor.

    HKEY_CURRENT_USER\Environment\TEMP
    HKEY_CURRENT_USER\Environment\TMP

    >Does it broke every email or just bigger email then some value (e.g. 3MB)?
    >How big email (in kb/Mb) are broken?

    All,regardless of its size.

    I assume you have x64 OS (because 5GB ram drive)
    Which OS exactly do you have?
    How did you created ram drive?

    >Changed below data with registry editor.
    >HKEY_CURRENT_USER\Environment\TEMP
    >HKEY_CURRENT_USER\Environment\TMP
    Because you have changed HKCU key I think that it doesn't affect services.

    Try to temporary disable
    Setup > Antivirus & antispyware > Email clients protection > POP3, POP3S > Enable POP3 protocol checking.

    When you turn of this options, emails are checked in Outlook, Outlook Expres, Live Mail and in Thundebrird by different way. Other email clients are not protected.

    Hello,

    What version of Microsoft Windows are you running?

    What directories do the TEMP and TMP string values point to in the [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\Environment] registry key?

    Regards,

    My OS is Windows XP.

    Didn't you know gavotte ramdisk or any other emulation tool?
    8GB-3.2GB=approximately 5GB.
    Study what is "ram-drive".
    http://en.wikipedia.org/wiki/Solid-state_drive

    My problem is already solved by oneself.
    I kindly reported problem and solution.

    How about talking clear English or not messing around and breaking your OS as your clearly not up to it.

    Error in user press delete button.

    Jisan thanks for report.

    I'd like more exact information about your os.
    Because you have written this
    '8GB-3.2GB=approximately 5GB'
    does that mean you have an Window XP x64 (or you have Windows XP on x86 and enabled Physical Address Extension [http://en.wikipedia.org/wiki/Physical_Address_Extension] - but I don't thing this is possible with client OS like xp)?

    Other question is Does your ram-drive improved an performance?
    Windows memory manager does file caching for temporary files my mapping them into memory.
    This can be much faster then accessing them on ram-drive. Of course it depends on application if they use flag for temporary files when they open files.
    I'd say that to have bigger memory on x64 for OS is much better then have a ram-drive. And I consider it much safer.

    Mark Russinovich disproved that any other memory optimization can improve a windows performance hoverer he doesn't discuss ram-drives. Most of memory optimizers try to force Windows to free memory that is devoted for file mapping into memory.
