What is an HSH file?

HSH files mostly belong to O&O DiskImage.

Primary Use: HSH files are used to store hard drive image backup metadata. They are generated by backup software such as O&O DiskImage, and the file contains the data used to recreate disk images.

Other Uses:

• Thumbnail Cache: Some HSH files serve as a cache for FastStone Image Viewer, holding thumbnails to speed up image loading.
• Game Map Files: In other cases, these files hold map data used by Halo Custom Edition.

FilExt.com note: For more info, visit O&O DiskImage or FastStone Image Viewer. Use the proper software to open or view these files, as each variant requires a specific application to interpret its content.

How to open an HSH file

You need a suitable software like O&O DiskImage to open an HSH file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your HSH file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a HSH file directly in the browser:. Just drag the file onto this browser window and drop it.

HSH format details:

If you know the file format, you can also find out how to open or edit the file. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. However, different programs can use the same file extension, and file extensions can be assigned incorrectly. When there is a problem with a file, the first step to solving it is to determine the file format. In the following you will find our evaluation of the HSH files:

The HSH file extension is not widely used. Such a file does not have a uniform file format. The file formats most commonly found in HSH files are:

• 20% of all HSH files use the same file format, which can be identified by the letters "1.0" at the beginning. If you open these files in a text editor, you will see only illegible characters. Most of these files are 1 MB to 140 MB in size. The file type is relatively new. DriveC.hsh is a typical file name.
• 5% of all HSH files are Kudo catalog Hash data files. If you open these files in a text editor, you will see only illegible characters. The file size is in the range of 460 bytes to 2 KB. The keywords FASH are typical for these files.

The remaining 75% of all HSH files are different files with different signatures, such as ELF and certificate. The category is docx, dkvfe or round. You can get all the details of your HSH file by dragging it onto this page or by clicking the button "Choose your .hsh file to analyze" above.
