Open THUMB File

THUMB files may refer to those named THUMBS.db or those with the THUMBS extension.

In any case, both are thumbnail image files, used by the system of almost all the most popular operating systems.

The THUMB file works as a database of browser thumbnails for operating systems, be it Windows, macOS, or Linux.

That is to say, it was in charge of saving information about the thumbnails that the computer had to show as an icon of the files that a certain folder contained when accessing it from the operating system explorer.

At present, and for a matter of comfort for the user and security, the operating system developers decided to change this behavior and currently the THUMB files are no longer generated, but rather it stores all the information related to the thumbnail cache. in a single location whenever you need it.

THUMB files are necessary?

THUMB files are usually hidden files, and an inexperienced user may confuse them with an important operating system file, which, there is a myth that deleting it will cause some kind of performance problem in the operating system.

However, nothing is further from reality, you can safely delete all the THUMB files you find on your computer.

The only 'but' that we can add to this is that these files are quite recurring, and it is normal for them to reappear over time, especially if we are working with an old OS.

Open a THUMB file

If you try to open a THUMB file, you will most likely open a scaled-down version of the original image, meaning a smaller image, and perhaps much lower quality.

In some cases, videos also generate a THUMB file, and in the case of a video taken on an Android device, you might find a THUMB file, but with the DTHUMB extension.
