Slow NAS using Explorer file copy

I have a network home gigabit. Based on a linux NAS (qnap), 3 win xp & 2 win 7 ultimate.

NAS is the centralized storage for all media/files of all these computers.

Copy/access to the file of XP machines is perfect. But Win 7 is dead slow. Connected to the switch with Cat 5e cable, I get 100 Kbps (not firewall & no other activity on the network). Overall, when I get desperate and let him finish at the speed of the miser, it ends at all.

All the drivers are up to date.

A couple of PC are old, but the two that I bought in the hope of getting rid of this slow access are all new i5/i7.

I read a lot of posts on the net on various fixes. I also tried a few, but no result.

Please don't not/response theory on storage cards post / / speed/network access hard disk etc.

I read everything and I'm tired.

Yet once, in my setup NAS box isn't a problem. Works perfectly fine with XP.

Network card is not a problem. It's because using an ftp client to copy files from the NAS, I get a good 50-60MBPS (YES on the same PC WIN7, for the same files. It is not for a single file. I have FTP'd about 1000 100 GB in size (big and tiny files included)). But this speed only lasts until I open Windows Explorer. As soon as I did this, the speed drops to a crawl. So if I want to get all files in the NAS, I have to restart Win7 and ftp before you open the Solution Explorer.

Read all the messages on this SAME forum, there are hundreds of cases where this has been reported. And I haven't read a SINGLE instance where Microsoft agreed, that's a problem with Win 7.

Personally, I keep not if Microsoft accepts or not, BUT after making a lot of money off the coast of their customers, I would expect Microsoft to CHALLENGE this as soon as POSSIBLE an automatic update.

After writing this monologue, I'd wait for the moderator/decision-making people in charge to answer WHEN WILL THIS GET FIXED.

After spending $ 2000 on the hardware to find out that there is a problem with WIN7, I was more sober and more civilized write this upward.

For the rest of the team, I hope that my FTP autour work is useful to someone in desperation (like me).

Hello

I also have a NAS.

Only that my SIN is Windows Home server, and it works very quickly.

Speed (see here), http://www.ezlan.net/vista/Giga-Optimized.jpg

It is 70 MB/sec (B = bytes).

You call that a problem with Windows, I call it a problem with Linux (the old story of chickens and eggs).

    Always there are people who use Windows Xp, the problem is that when I copy the files in my USB and use it in my friends house, then Windows XP said 'pen drive not formatted ".

    How is the "pen drive" formatted - with what the specific OS file system?
     
    This is more likely to be a file system - do not operating system (although related, not as much as you might think)-problem.  Another possibility is a problem hardware or bad driver on the machine Windows XP itself.  It could also be, although rare, an incompatible 'USB key '.
     
    What is the 'pen drive' is formatted with the file system is essentially - the first question to ask.  Then - if I were you - I everything on the 'pen drive' copy on a computer which can be read - if committed to the machine more common denominator (in this case the Windows XP machine) you will use and FORMAT this 'pen drive' using this machine.  One of the few possible things will happen no doubt...

    (1) you'll find you format it with a version of NTFS that will work in all areas - all the machines that you can use with Windows XP or more on them.  Then this problem will disappear.

    (2) you will find there * is * something wrong with the Windows XP specific in question and this machine is not a problem easily solved this and your "pen drive" probably will work on someone elses machine Windows XP very well as it existed before.

    (3) you will end up with a FAT32 formatted "pen drive" that should work on most any system - as long as you don't need to transfer * really * large individual files.

  • To use Robocopy to copy files, but you will notice that after the initial backup, it ignores the unchanged files, but I don't want it!

    Hello

    I use robocopy in Windows Server 2008 R2 operating system.

    Here #1

    I would like to use Robocopy to copy a disc (z) files on an external drive (f) and want to "full backup" every time regardless of whether the files have been modified.

    How do I do that?

    I tried to use the command

    Robocopy z:\ketchup f:\ketchup/e

    It works very well if there is nothing in this record, but once the initial order has been executed. It will skip all files of unchaged but I want yet it backs up to the top anyway.

    Want to #2

    I would like also to add a unique name that includes the date and time I'm it backup (in essense a new backup folder name that contains the date and time).  Hoping to place it under scheduled tasks as soon as I get going.

    Hi Jess,

    Your question of Windows 7 is more complex than what is generally answered in the Microsoft Answers forums. It is better suited for the IT Pro on Microsoft Windows Server public. Please post your question in the TechNet Forum. You can follow the link to your question:

  • My windows Explorer stops working when I try to use the file menu on a file.

    My windows Explorer stops working when I try to use the file menu on a file. If a file is selected in a folder that windows Explorer will be display Windows Explorer has stopped working the message box. This occurs only if a file is already selected and you click on the file option in the menu bar. All the other menu items work well if a file is selected or not, and if no file is selected the menu file works fine. I already ran SFC/scannow from the command prompt, but it returns no violation.

  • By default Windows Explorer setting - copy the files instead of move

    Is there a way of installing the my documents folder (and all that it contains) so that it always copies files, rather than move them.  "I often move the files of people to my"my folder"Documents on my desk to work on it".  I'd rather have the files copied and not moved so that I'm not move or modify the original.  Is it possible to set this up?

    Depends,

    If you drag files click right use drag and at least, you can use the list of options to choose from.

    Or you can use Alt + EF and that copy into the folder, and then navigate to the folder.

  • Very slow file copy speeds

    Hello

    Recently, I myself have built a new PC and am currently under Windows 8 Pro about this. I had a problem with copying files between spaces of storage/drives on the PC. Whenever I start a file copy/move operation, the speed starts usually at a respectable speed (ie. 40 - 50 MB/s) and then quickly descends and hovers somewhere between 50 Kbps - 800 KB/s, sometimes up to 0 KB/s for a few minutes. Try to copy a large file (ie. 10 GB) takes a few hours/days where on all my other machines it would normally take a few minutes. I tried to use Teracopy to see if it could work around the problem, but it seems to have the same problem. If I transfer a file from my laptop to the computer over the network (leave the laptop to control transfers) he will sit at a constant 5-8 MB/s well. Even less than ideal but much faster than what he does internally. I have also updated the bios on my M/B to the latest version just to rule out it as a problem does not.
    I was wondering if someone could point me in the right direction on this problem and help me figure out what causes the congestion. If it helps the machine is an i5 3570 k, Asrock Extreme 4 M/B, 16 GB of DDR3 ram and a Gigabyte 7950 GPU. I have also several HARD drives more a 830 SSD from Samsung for the system drive.
    If anyone can help me with this problem I would be very happy!
    Thank you!
    Chris

    Sorry guys for not not getting back to this sentence. I managed to solve my problem.

    I thought I would test all HARD drives in the storage space and running a benchmark on them to see if they are any ball game. It turns out that one of them was not. Its read/write speeds were about 1% of what all other players received.
    So I think problem solved... FAKE! My storage pool was divided into several spaces more that contains media files on single spaces more personal files and photos etc on two way mirrors spaces. It turns out that you can't remove just a drive from the pool as you can in WHSv1 if there is single spaces in the pool. I ended up having to save all my data on another PC (fortunately I do anyway!), remove all the spaces of the pool and then he'd let me remove the drive from the pool. After that, I could finally rebuild all the spaces and then copy all the data back on.
    If MS wants this technology to be taken seriously, they NEED to implement a way to replace failed or upgrade to larger without records to delete all the data, or it is next to useless.
    I hope this could help someone...

  • How to copy the database using rman file from another location.

    You can clone data base using the files of rman backup from somewhere else (on the server to clone).

    I have two server db source and clone db server.
    I normally copy the files of RMAN backup to clone server (under the same folder structure, as it was on the source server).

    The purpose of the test, IE I don't have same partition and free space on the source server and the clone.

    I usually use under notes to the clone.

  • Corruption in large file copy to USB - Windows 7 Pro 64-bit SP1

    I have seen other people have reported this problem, but I have not found an answer.

    When I copy large files (1 GB +) from one hard disk to another (connected to the same computer), and the destination hard disk is on a port USB3 (also maybe USB2), sometimes the file is damaged somewhere towards the end.  Usually, the copy is fine for 60 to 80% of the length but the rest seems so be given totally random.
    If I copy the file even over and over again between the same two discs, usually, I keep getting corrupted copies (but not in the same place).
    If I copied the files to a different destination drive, usually the problem goes away.
    I tried to use the command COPY to command prompt, same problem.
    I tried putting the drive source on a USB2 port, so the copy goes much slower, still get corruption.
    I ran a test of the RAM for 6 hours with no problems found.
    I tried to run a "Linux" operating system on the same computer with drives connected to the same ports, and copies were all good!  But much more slow (about 30 MB/sec instead of 100 MB/s).
    Because Windows checks the accuracy of copy of file, it would be a big problem, even if it is not reproducible - but since it is "all the time" and "over and over" with the same files, it's all just crazy!
    I have another question strange memory.  I have two 4 GB DRAM sticks in my computer, but the properties shows my memory as:
    "GB 8.00 installed (3.98 GB usable)" and right it says "64-bit operating system" - so why can't we use half of my memory?
    Processor: AMD FX-6100 3.3 GHz not overclocked-card mother ASRock 990FX Extreme 4
    Note that I have no problem with other programs of writing large files on the same hard drive, for example the output of a video editing software has no problem.
    Suggestions?
    Thank you

    I THINK I FOUND THE PROBLEM!

    This is the X - Fast USB program supplied with the motherboard ASROCK.
    If you have X-Fast USB running (and you know), UNINSTALL IT, reboot and this problem may disappear.  So if please contact ASRock and let them know that their program is ruining your life.

  • Since the update Windows 10, my CS5 Photoshop created jpg are no longer visible in Windows Explorer (File Manager)

    Since the update Windows 10, my CS5 Photoshop created jpg are no longer visible in Windows Explorer (File Manager).  I have reset Photoshop like application default for jpg files, rebooted.  Nothing has changed.  The ideas people?

    Hi R_Kelly,

    Hidden folder/file settings was the first place, I checked and kept checking each new reboot.

    I have copied below my temporary solution I posted in another forum thread.

    See point 7.  I found a way to make it visible again.

    1. I can see all jpg files created before Win10 update AND all the jpgs created by other programs, other than Photoshops after Win 10 update.

    2 Photoshop cannot see the newly created Photoshop created jpg files in the file picker at all since Upgrade to Win 10.  I've never had a problem of invisibility of file before winning 10 update.  My hidden files were always checked to be visible.  However, Photoshop can open if listed files in a basic text file search in Windows Explorer in the path of the file "recently used".

    3. the files are not visible or clickable at all in Windows Explorer tree or the Photoshop file selector. They become open and visible when listed in a basic text file search in Windows Explorer in the path of the file "recently used".

    4 Microsoft Office applications can't see the new Photoshop created Jpg files in file, only pre Win 10 update pickers jpg created by other applications and versions.

    5. the problem occurs only with Photoshop jpg created after the Win 10 update.

    6. I checked the settings "Show hidden files, folders and files of the operating system", and they remain as they were, which allows all the hidden to visible objects.  I kept the visibility settings files in this way since the early 1990s.

    Temporary fix below *.

    7. I did yet another simple search of the text Windows Explorer, he finds invisible jpg files less all links 'recently used' who were there yesterday (2nd day after I created the files), I checked the location of file properties file and it entered the original file I saved their.  Using a right-click of the mouse on the file to bring up the menu actions and file properties, I was able to copy and then paste the file into another directory.  I jumped on the directories to see if it remains visible and he (Yes). The new copy is now visible to the pickers of file in Photoshop and Microsoft Office applications.

    Anton

    Unless the site you develop is for the Asian market, I don't know why you want to use that particular font. The Basic, standard and digital alphabet punctuation glyphs has sans serif, Roman characters, but the rest is thousands of Kanji characters. While you can use the font .ttf and .otf and web fonts, it would be very unusual to use one so great. Pages should load quickly and 78 MB, with a value of faces to download for those who have connections slow Internet is not fast.

    I would take a different font without serifs. There are literally thousands who look identical or virtually identical to Yuanti.

    131 free and high quality without font serif to choose here. I'm sure you can find a desired.

  • FTP .txt file copied correctly the cRio

    I use the 'FTP Get File.vi"to retrieve a .txt file of my CRio, which is then copied on my host.  The file is a delimited data tab.  The file copied all the data a except that the copy has a blank line between each set of data.  These additional lines take me to read the incorrect lines when the file is read in my program later with the "reading a spreadsheet file.  These additional lines come  I checked the original on the cRio file transfer via MAX and these lines do not exist.  Can someone tell me how to solve this problem?  Thank you

    If you look at the entries for the File.vi FTP Get, you will notice that there is one that says binary:

    By default, this is false, which means that it copies the data in an ASCII format.  Try a real constant of wiring to this entry.  It's the need for VxWorks and Windows use different end of windowing.  This difference is probably the reason that it is adding lines to it.

  • File copy operation

    I was wondering how do you file copy operation?

    Should I first?

    Kind of stuck here

    Thank you!

    The prefix of the correct URL is active: / / /, not assets:.

    But QFile is not a class of Cascades and perhaps do not understand this prefix at all.

    Try:
    QString from = QDir::currentPath() + "/ app/native/assets/images/image.jpg";
    QString = QDir::homePath() + '... / shared/camera/image.jpg ';
    QFile::copy (from, to);

    Also access_shared permission must be paid bar - descriptor.xml

    UPD:

    Try logging & values and verify that files with these names actually exist on the device. If the roads are bad, adjust them accordingly. Device Filesystem Navigator in Momentics can be used for this.
