  • When I turn my library of music in format mp3. I have duplicates.how can I know which songs are mp3

    I have a mp3 player.i sansa player - tunes doesn't recognize Sansa, so I need to transfer my music in windows media player. to do this I need to convert all my music in mp3 format.when I do that, then I can burn all my music and import to wmp.question is that when I convert to format mp3, how will I know which songs are mp3?

    You can create a smart playlist which, for example, collecting files converted based on the date that they are added to the library. It depends on how you want to proceed. If you want to permanently convert, I have a script called ConvertFormat which range the originals after conversion. Alternatively, you can temporarily change your media to the converted files folder are stored in a folder of new media, then once the process is complete you may add these files to your WMP library, reset the media in iTunes folder and delete the new additions to iTunes library, thus separating the two libraries.

  • How can I find which files are missing in my video so that I can burn it to a DVD? Help!

    have made a video for my friends moving away party (his tmrw night, I need this burned on a DVD as soon as POSSIBLE!) So the film has mainly pictures, with a few songs mp3 in the background and some wmv files. OK, everything works correctly in Windows Movie Maker, and as soon as I click "publish on a DVD" I get a box saying that it saves and will be reopened in Windows DVD maker. This isn't so. Create DVD opens, I can't open my project, not to mention burn my DVD. I get a msg saying that he cannot locate one or more of my files... Help! How to determine WHICH files are missing so I can get this company to burning? I need this burned as soon as POSSIBLE, please help me!

    Are 'all' the original files that you have included in your project
    saved on your hard drive? This is important because
    Movie Maker does not archive copies of the files... it
    just saves the path to the original location. If these
    the files are no longer available Movie Maker cannot find
    them.

  • How can I know which files are accessed more so I can move them to another drive

    My C drive is constantly busy and is indexed to 100% much of the time.  My swap file is on my S drive and its activity is very low. How can I know what is causing all the readers of the activity on my C drive so I can move some things my S, or other?

    I realize it is not easier to simply move the files, I might have to reinstall some applications or other things. But for now, I don't know what are the files or applications, roll to the top of the activity on my C drive.

    You can use performance monitor. Type perfmon in the "Search" box and press "Enter."

    Open the drive section by clicking on the arrow

    To identify individual files in more detail, you will need the Windows Performance Toolkit

    http://msdn.Microsoft.com/en-us/performance/cc709422

    http://msdn.Microsoft.com/en-us/performance/cc825801

    Download as part of the WIndows SDK from here:

    http://www.Microsoft.com/downloads/dlx/en-us/listdetailsview.aspx?FamilyId=6b6c21d2-2006-4AFA-9702-529fa782d63b

    Select this option for components you need.

    There is a video on the use of the tool here: http://channel9.msdn.com/Events/PDC/PDC09/CL16

    At a glance, use Process Explorer to identify the source of the e/s:

    http://TechNet.Microsoft.com/en-us/Sysinternals/bb896653

    On the file menu, click "show details for all processes."

    On the view menu, click on "Select columns" and check the deltas of reading and writing.

    You can also use the process monitor:

    http://TechNet.Microsoft.com/en-us/Sysinternals/bb896645

    This will show you the operations of individual files so the amount of data will be huge. If a Visual inspection reveals anything, you can export the data to a csv file and use a spreadsheet to a total activity for each file.

  • How can I determine which commands are associated with private 2-14

    I don't want to create command authorization sets just used a private level. I can't determine what commands are assigned to what level priv?

    By default, there are three levels of command on the router:

    privilege level 0 — includes orders to disable, enable, exit, help and logout.

    privilege level 1 - Normal level on Telnet; includes all commands on the router user level > prompt.

    privilege level 15 - includes all orders enable-level at the router prompt #.

    Orders at level 2-14 are empty by default, BUT you can always access all orders at your level and below, so if you are level 4 you have access to the commands at levels 0 and 1

  • [Linux] How can I see if there are new messages without opening Thunderbird?

    Hi people

    I am working on Linux Fedora (20) and wonder if there is a way to see if I have new emails without opening Thunderbird again. I usually minimizes Thunderbird and when a new message arrives, I get a notification from the office, which is great. But - if I am away from my computer for a minute, and an email arrives, I will often not see until the following is available in.

    On mac, the thunderbird icon would get one of these badges + 1. Is there a way to do this? For example, to have the title of this change of window pane Thunderbird "Inbox - Mozilla game...". «to "consult [2] - moz...» ' - or just leave the notification until I have the click.

    Thanks for the tips.

    See you soon

    To my knowledge, Thunderbird does not provide these features by default. You can use the Add-on Firetray achieve the same, however.

  • How can I see / change ports smtp used by 12.0 FF on my old WIN2K?

    My webmail account works, although slowly, when I use NetScape 7.1. When I try to use the same program and service with FireFox 12.0, I can receive emails, but sending email gets me an error message is something like "Could not establish a SMTP commection with the server." The service tells me that my outgoing smtp port is 465 if I use SSL and 25 if I do not use SSL. Also, if I wonder about "authentication", it should be "identical entering.» Where can I find these settings in FF12.0?

    I ask this question on another computer, not that I have problems with. My problem is an IBM Aptiva running Windows 2000 Version 5.0 (Build 2195; Copyright SP4) 1981-1999 Microsoft Corp. Physical memory available to Windows: 64 824 KB

    SMTP is not webmail. It is a protocol for sending e-mail, used by such as Thunderbird or Outlook Express email clients.

    Unlike the deceased Netscape, Firefox does not include an email client. You can try the add-on Simple Mail to add this feature to Firefox.

    Normally, alternatives would be using Thunderbird as an email client alongside Firefox or Seamonkey instead of Firefox. However, the latest versions do not work with Windows 2000.

    You should really consider replacing this computer. The operating system and browser are precarious, and which is probably the case for the software plug-ins and browser security. A list of the vulnerabilities corrected in Firefox since version 12.0 is quite long:
