DB file is a database that stores thumbnails (in JPEG format) of all image files in this directory ). A thumbs. DB file is generated when a thumbnail is viewed (displaying an image or film. Thumbs. DB is not a virus, but a database file. It can be found in a folder with images, and its size increases with the increase in the number of images in the folder.

In Windows XP Media Center edition, an ehthumbs. DB is generated to save the video file preview.

In Windows Vista, Microsoft canceled thumbs. instead, the thumbnail Database "thumbcache_xxxx.db" is stored in \ Users \ [user name] \ appdata \ Local \ Microsoft \ Windows \ Explorer.

Thumbs. DB is a cache created for image files in the current folder in Windows XP/2003 to improve the response speed of folders in the thumbnail view mode. This file is not a major problem, because it is a "system file + hidden file", it is usually not displayed (unless it is set in your computer ). But sometimes it is quite troublesome, and may even bring some security risks to the web site.

For example, when you upload a digital photo to your computer, you delete one of the "ssa2501" and then change the "ssa2502" to "ssa2501, the "ssa2502" photo was immediately changed to "ssa2501", not just the name, but also the photo. If you rename "ssa2503" to "ssa2502", a miracle occurred. The original "ssa2502" photo came back, and the "ssa2503" Photo disappeared!

Is it poisoned? No! In order to display images faster, Windows XP automatically saves the thumbnail of the images in the folder as the index file "thumbs. DB ". After we delete useless images. DB "cannot be automatically updated immediately. When a new file is named the same as the original file, the original thumbnail is taken out. In fact, the image itself is not changed, but only the thumbnail of the image is changed. However, this will mislead the user! The more serious consequence is that if a Web site creator sets the Windows folder option to display system files and hide files, he made or collected a large number of images to a directory during website creation, and previewed the directory in a thumbnail, then he accidentally uploads the entire directory or all files to the server. DB is also passed, because a tool is available to view thumbs. the contents of the database, or even the images in it, so that the browsing permission of this directory is enabled. You can use thumbs. DB obtains all the file names and thumbnail content in this folder, and then you can use thumbs. the DB browser downloads all the image files in this directory and browses them. The worst case is to let others find that this thumbnail contains unhealthy content...

You can use the search function to retrieve and delete all thumbs. DB files. Or generate a. CMD file. After running, all problems will be solved.

The method for generating the. BAT file is as follows: Create a text file and save it as the delthumbs. CMD file.

For % A in (C: D: e: F: G: H: I: J: K: L: M: N: O: P: Q: R: s: t: U: V: W: X: Y: Z:) Do del/f/S/Q/A % A \ thumbs. DB
