How does thumbnail generation work? RRS feed

  • Question

  • I hoping someone can confirm how the generation of the thumbs.db file works on network drives.  What I'm finding is the first time I access a directory with pictures the thumbs.db file is created, fine.  When a second user accesses this directory the thumbs.db file is updated and grows.  When the third user accesses the directory it gets updated again and grows some more.  The size with which the file grows doesn't seem to be consistent, sometimes by kilobytes, sometimes by megabytes.

    What we're trying to do is limit the amount of network traffic that occurs when users view directories with large amounts the pictures.  We're wondering if we'd be better off disabling the thumbs.db generation altogether

    Can anyone tell me why the file is growing and/or what exactly is stored in this file?

  • Hi,

    Windows Explorer is fairly intellectual and enters the thumbnail mode automatically when the user views a directory with a large percentage of graphic and video files, Windows stores the images for thumbnail previews in cache memory so that it can redisplay the images quickly, based on understanding, when you view more files, it cost more space.

    If you want to disable the thumbnail, you could refer to the following article:

  • So does thumbs.db actually contain a small thumbnail picture of each picture in the directory?  If so, why does the thumbs.db grow when the second user looks at the pictures even though no files have changed since the first user looked at the directory, shouldn't it just load the thumbnails from thumbs.db?

  • Hi,

    What is the operation system of the file server and the client?
