Windows 7: Windows 7 cannot copy DVD with large number of images

Windows 7 cannot copy DVD with large number of images

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?

Hi there
It's a "Roundabout" way but this should work and be quite fast.

If you have a decent backup program (NOT WINDOWS STANDARD BACKUP) that is capable of copying DATA as well as just "Imaging" a disk / partition then this method will work quickly and easily.

I'm using ACRONIS but any decent commercial backup program will work similarly.

1) Backup the data to a spare area on any disk. The file will be called something like xxxx.tib in the case of acronis.

2) Now Restore the data to your USB device.

Job done --easily and very quickly normally.

Hi Jimbo,

Many thanks for your suggestion.

By the way, any idea why Windows takes so long to process large numbers of image files?

Hi there
No Idea -- might be some way in how Windows 7 READS the image files -- I assume it's jpegs --- it might be making thumbnails since its building a directory in the memory buffer. With 1000's of images it will just run out of memory.

Some Windows 7 Guru might be able to suggest a method of "Disabling" this -- but I leave that to others more qualified on that particular topic.

Commercial backups just read data as Binary - doesn't matter what format its in - and usually have very sophisticated and efficient compression (LOSSLESS of course) algorithms built in so they operate extremely fast in most cases -

For example say you have an image which consists of 75% Blue sky -- the pixels will repeat for 75% of the file -- well the compression could just say pixel A RGB (Red Green Blue content) Repeat for next n times where n = 75% of the image. So it would write the pixel plus the code for copying this pixel until the next DIFFERENT pixel was encountered. Very fast and efficiently compressed.

Cheers

Hey Jimbo, yes they are JPGs, and if Windows is creating a thumbnail when all I've asked it to do is copy the files then that must be one of the worst OS design decisions ever (at best!).

If that's what's happening I'd be really grateful if a guru could advise how to disable such nonsense. I have some more supplier product catalogues to copy soon and it's a real pain the way Windows is failing at this simple task.

Hi there
Why not solve the problem by a completely different way.

I believe you can get the FREE PICASA application from Google

Picasa 3: Free download from Google

Very fast and a real good way of managing images / thumbnails / catalogs.

Don't worry about having to use a "cataloguing" type of application -- with those amount of images you'll need something better than windows to manage them anyway.

Have a look at the application -- it's 100% free, simple and easy to use and as its GOOGLE it won't go out of business any time soon.

Any professional organisation managing images WILL almost certainly have cataloguing software.

Cheers

Hi Jimbo. Thanks but all I need to do is copy the files for backup purposes at this stage. I'm not at all interested in thumbnails or viewing the images. I'd just like Windows Explorer to behave like a decent application and do what should be a simple and easy task - copying files without fuss. If it can't do that then I'd like suggestions for replacements for Windows or Explorer.

I do not know if you have Windows 7 SP1 installed as you did not mentionned it, but there's known issues in the previous RTM build about backing up large amount of files.

Just in case search here:

Thanks NoN. I didn't know about that. Yes I have SP1 installed. Is it fixable?

There's a registry fix to increase the amount of files selected to be moved. Because Windows 7 & Windows 7 SP1 by design can't take more than a certain amount.

I'm searching right now the infos where i got that a while ago and did applyed to myself already.

Damn MS Page to dig!!
