dsfok is a simple and tiny application (barely 76 Kb) that, despite its small size, allows you to perform a series of functions such as making backups of any partition of a hard disk.
In addition dsfok allows to create the ISO images of CD-ROM or DVD-ROM discs, as well as to create images of the contents of diskettes. These images can then be restored from the program itself.
Also dsfok allows encrypting and decrypting files, truncating long-length files, scanning computer volumes for information, concatenating two files with each other, etc.
You can free download dsfok 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
