Disk Image Formats
| Content | Preference | Format | Format Use | Notes | |
|---|---|---|---|---|---|
| Preservation | Access | ||||
| Disk Image | Preferred | RAW(IMG,DD) | X | Often disk image formats are split into smaller files that are stitched together in sequence, often in 2GB chunks. When this occurs, many systems use sequential file extension numbering to delineate the relationships, e.g., myimage.001, myimage.002, myimage.003; or yourimage.e01, yourimage.e02, yourimage.e03. When this occurs, it is imperative that original filenames AND extensions be preserved so that they can be re-instantiated upon delivery to an end user (otherwise it will not be possible to put the sequence back together in the proper order). | |
| ISO | X | There are possibilities that some ISO files are merely RAW files that contain ISO file systems within them. Some ISO files may be pure copies of ISO file systems. | |||
| BIN/CUE | X | Often disk image formats are split into smaller files that are stitched together in sequence, often in 2GB chunks. When this occurs, many systems use sequential file extension numbering to delineate the relationships, e.g., myimage.001, myimage.002, myimage.003; or yourimage.e01, yourimage.e02, yourimage.e03. When this occurs, it is imperitave that original filenames AND extensions be preserved so that they can be re-instantiated upon delivery to an end user (otherwise it will not be possible to put the sequence back together in the proper order). Only .BIN files (and sometimes .ISO files) include sidecare .CUE files. The .CUE files serve as metadata for understanding the type and composition of data stored in the .BIN (or .ISO) file. | |||
| EWF-E01 (EWCF-ASR02) | X | Often disk image formats are split into smaller files that are stitched together in sequence, often in 2GB chunks. When this occurs, many systems use sequential file extension numbering to delineate the relationships, e.g., myimage.001, myimage.002, myimage.003; or yourimage.e01, yourimage.e02, yourimage.e03. When this occurs, it is imperitave that original filenames AND extensions be preserved so that they can be re-instantiated upon delivery to an end user (otherwise it will not be possible to put the sequence back together in the proper order). | |||
