About
dfirOS Viewer opens supported disk images on iPhone and iPad. Select an image in Files or on external storage, then browse folders on demand without importing or indexing the entire image. For split images, select the segments or grant access to their containing folder.
Preview individual files, inspect metadata and hex bytes, and calculate a selected file’s hash. Evidence is opened read only and remains on your device. This is a viewer; image wide analysis and reporting are available in dfirOS for Mac.
