Deleting Large Number Of Files Very Slow
Apr 17, 2012
I run a software tool that often generates 75,000 - 100,000 small files that need to be deleted after the software exits. Right now, it can take 8 - 10 minutes to permanently delete all these files from a single run, and I usually have 4 - 8 runs to deal with, so do the math. I have tried shift-del to permanently delete but it doesn't work - Windows still copies everything to the recycle bin. Also, while moving the files to the recycle bin, I often get an error message: "Error 0x80070050: The file exists." Bottom line is that it takes a *really* long time just to delete these files and I need a quicker way to do it.

My main HDD is comfigured into two partitions, C: for Windows 7 and D: for data/downloads/etc. Whenever I copying a large file from Partition D: to Partition C: and vise versa, the transfer slows down to a crawl and the HDD activity light on my case stops blinking.

Everything is so slow e.g. opening of FireFox, opening of Excel, opening of Task Manager etc. While I'm copying 750GB of data from one partition to another partition, why? I'm running Windows 7 x64 7100 on a separate partition and I have a Q6600, 4GB ram and 5 X 1 TB WD Black edition drives...Task Manager is showing 33 running processors, 3 - 5 % CPU usage and 1.35GB of ram usage. Is this a Windows 7 bug? Windows 7 is super fast when I'm not copying/transferring large files between partitions!

I'm trying to copy a DVD catalogue with over 30,000 product images onto a USB backup drive. Windows 7 Explorer cannot seem to do this. It copied some of the files but then just stopped copying.I rebooted my machine and tried to copy the files again but Windows reports that it's going to take almost 4 hours to copy! I suspect, however, that it will fail again to complete the task. The backup device has a data transfer rate of 450Mbps so it really shouldn't take that long, surely? Is there other software I should use that's better than Windows Explorer? Or some other method to accomplish what I would have expected to be a simple task?

Clicking on a large folder in Explorer can cause a slowly-moving green progress bar. In some cases this can take several minutes to complete.
A common cause is thumbnail caching of image and video files, resulting from having properties | customize | "optimize this folder for:" set to pictures, vs documents or General items.
The most likely solution: in Explorer, right click on folder, select properties, customize, under "optimize this folder for:", select either General items, or documents. Set check box "Also apply this template to all subfolders", then click apply.
The slow progress bar is apparently caused by Explorer scanning the folder and all subfolders to pre-render thumbnail images for image and video files. This happens if the "optimize this folder" setting is pictures or videos. This happens when merely clicking on the top-level folder.
If "optimize this folder" is set to documents or General, the thumnails are not rendered until you actually click on the folder or sub-folder containing those.
This was discussed in another thread on this forum, but it was full of speculative remedies, and the actual cause and remedy was not posted until the last thread (and one year after the thread was started): Accessing drives in Windows Explorer takes a long time I'm creating this thread with a more exact title and concise description, to aid in finding the solution based on a symptom search.
While the above is the most likely cause of a slow Explorer progress bar, there are other possible causes. These include clicking on a remote folder on a slow network, general slowdown due to indexing, disk drive or filesystem caching disabled, disk drive retries due to impending hardware failure, corrupted video files or codec, etc.

I have installed Windows 7 on several computers, both laptops and a desktop, and I am having real trouble with extremely slow copying, transferring and deleting files and directories. What used to take minutes in XP, now takes hours, particularly the "preparing to copy" phase.

My OS is Windows 7 Home Premium. My IE version is 8.0.7600.16385. It's been working well until last night. Now suddenly, when I'm trying to go into large websites, everything takes halfway to forever to load. I even restored to any earlier point. Still the same problem. (By the way, I had difficulty restoring. I kept getting error messages. In the end I uninstalled Kaspersky, restored to an earlier point, reinstalled Kaspersky.)

Just about every time I try to permanently delete a large file or folder, either by shift/delete or emptying the recycle bin the operation hangs up.The little window opens and it counts up the size of the file and that it. Nothing else overtly happens. The status bar never starts indicating and the window just sits there with the little green lights chasing each other across it. If I try to cancel or close the window it nothing happens.During the time all this is going on, I can hit ctrl/alt/del and select Task Manager and it simply goes back to the desktop with this window still squatting there doing it's thing. I have pinned TM to the task bar and tried starting it from there but it never starts. Eventually everything just slows to a stop and nothing works which would seem to indicate some kind of memory leak. There are no error messages during any of this.I have to hit reset and restart the computer that way in order to regain control and we all know how bad an idea this is. I've already had my boot sector eaten once causing me to have to do a total rebuild and I'd prefer not to have to do it again.

I usually send clients large images around 4Mb via the email. I also upload to various sites, files up to 15Mb. They are all usually jpeg or .psd format.
For some reason it just doesn't work anymore - they get so far and seem to just hang. I contacted my ISP provider and they went through all their trouble shooter but told me that the problem is my end.
I am using Windows 7 64 bit. I have tried IE9 and Google Chrome but neither helps. I use Microsoft Security Essential. I have tried turning off the firewall but this doesn't work either.
Smaller versions of the jpegs seem to upload OK. I haven't done anything to change what I am using recently other than to run the automatic updates.
I have internet satellite using an ipstar modem. No router.

I was wondering if there is an option/program that you can use, to get rid of ALL the files that you haven't used for 1/2/3/4 months or more?I'd like to get rid of all theunnecessary/junk files that possibly hung on even after I uninstalled the software etc.Since I don't remember everything I've ever installed I would just like to get rid of everything on my pc that hasn't been used in let's say 2-3 months. I am using Win7 Ultimately hope I was able to communicate my issue correctly as English isn't my first language)I did do all I can manually, but you see my PC has 60GB on the (C) drive and it's currently using 50. I do have (D) and (E) which both have a terabyte each, but I would still like to get to the bottom of why (C) is so full even after I have cleaned out pretty much everything that isn't essential.

If I installed a program like Lotus Notes on a 64-bit version of Windows 7 and then discovered that the program didn�t function the way I need it to and then restored the computer back to a point before the installation, would it be okay to delete the Lotus Notes folder that was created in the AppDataLocal folder since those files won�t be used anymore?

how to "delete" unwanted files on DVD Writable disks. Do I need another piece of software to do that or WIN 7 can do it.
Today, I took out an old DVD disk that had files written on it previously by NERO in XP, and added files to it. That was OK. But then, I need to replace one of the files, so I went and delete it, but I can find anyway to delete the file, now can I add any more files to the DVD it seems.
I went back to XP and use NERO on the same disk, deleted the file, replace it with new one, and all are fine.

I have literally many hundreds of .png files that serve no apparent function other than clutter. When I try to delete them the message is, "You require permission from "TrustedInstaller" to make changes to this file". "Unlocker" can delete these files but only one at a time. Is there software out there that can delete a bunch at a time?

My windows keeps deleting files with an .lz extension right after they are downloaded to there . It deletes them for ABSOLUTELY no reason . The antivirus doesn't scream , nor the folder and files are in C: or in a system folder. The folder is mine and those files are needed for a game , so every time i start the game it downloads them again and again. I Observe how they comeup in the directory , and right after they are downloaded , windows deletes them (they dissapear).

If you set the view to Extra Large Icons for video media files, it shows a screen capture from an instant very early in the video file (like in the first 5 seconds or something). Is there a way to modify what point in the video file the screenshot is taken from?

For some reason I am not able to transfer large files to my Windows Home Server (home build). The file will start to transfer then just stop and error out.
The error message says Network Error: There is a problem accessing serverfolder.
This is on a wired connection so I dont know why it would just be dropping the connection. I can still surf the internet fine during this time.
Realtek RTL8169/8100 network cart, cat5e cable, 10/100 netgear 24 port unmanaged switch, WRT54GL router(tomato firmware). NICs are set to auto negotiate.
Any ideas what could be causing this?
I attached a screen shot of the error message and network monitor.

I have a newer system with Windows 7 64-bit running. I manage many other machines and really have never had to think about the indexing service. It always seems to work decently although it has its faults.However, this is my personal machine and want it to work somewhat as it should and there's something way out of whack here. I built this system online and it has performed flawlessly. Not a glitch - except the indexing part of it.My hardware:1. Gigabyte H67A-UD3H-B32. 8 GB Memory3. Crucial Model 300 SSD4. WS 500GB Black Caviar HD5. 2 Dell Monitors6. Plain vanilla networking w/built in ethernet7. HP DVD R/W DriveI have configured what I want indexed and what I don't but not much of a change from Microsoft defaults. Services.msc reports that the indexing service and Windows Search servie status is "started" with "automatic" startup type.
The problem is no matter what I do my index only contains about 4,000 files. I have much smaller system that have over 800,000 files indexed and there's many more files on this machine. I've tried rebuilding the index many times, uninstalled and reinstalled the Index and serch services. Changed the registry to run indexing at full speed and left the machine on full power overnight and STILL always get around 3,000 to 4,000 files indexed. I have searched via the start menu and while in a folder using Windows Explorer. I check to make ABSOLUTELY sure I have the folder in the list of Indexed folders (control panel->Indexing Servce) and yet a search doesn't come back with ANY files. Occasionally, while searching in the Windows Explorer search box I'll get a message that I should add C: to my search list but it's already there. Obviously a few of the folders on the C: drive are in the exclude list but most are not.I know I haven't given much to go on here but I'm hoping someone will see something in my description that will spark an idea to go with that I haven't already tried. I wish I could give you a really comprehensive list of what I've done but I've been playing with this on and off for the last several months.

Everytime I try to extract a file to my desktop, the .exe shows up for a second and then dissapears but the other files remain. I turned off McAfee and rebooted but still no luck. The file I'm trying to extract is a trainer for a game if that helps any.

I have two .csv files on my desktop that have names that are too long, windows 7 will not let me delete them or change the names to shorten them, I can drag them around the desktop and that is about all I can do.
