File Format Issues
Camera RAW
Files
Some RAW file types that are corrupted or with very little fragmentation may be recognized as a TIFF file and not have the normal RAW file type name. This can happen if the EXIF data is corrupted or the end of file identifier is missing on some camera RAW files types. These files can sometimes be renamed to the correct extension and opened with the
default application. In some cases, an alternate photo editor may be needed to open and convert/resave the TIFF to a particular file name.
Kodak .KDC File Format
The Kodak KDC
file will be detected as TIFF file whose image data is a thumbnail image. Rename
the file extension into .KDC to use it as KDC file.
MOF Files: Files using
OLE Storage Format
A files that
uses OLE storage format and whose vendor could not be detected will have the
extension '.MOF'. This format is used by most new file formats like recent versions
of Microsoft Word, Excel, PowerPoint and many third party vendors. To gain access
to the file you have to rename the extension (e.g. to .DOC, .XLS or .PPT) and
then try to open the file with the right application.
MPEG-4 Video and Audio
(ACC) Streams
All
unidentifiable MPEG-4 streams
will have the extension '.MOV'. Rename the extension into '.MPG' or '.MP4' to
use them as MPEG files. Some movie files, especially HD, can be fragmented,
and may only partially recover. There are other solutions possible to further
recover the data, please contact Datarecovery@LC-Tech.com for more information.
Photoshop Files
If Photoshop
informs you that the images are corrupted, try to load them into another graphic
application and save them as TIFF files.
Windows Media Audio/Video
(WMA, WMV)
These files will
be detected as .ASF files. Rename them to use as .WMA/.WMV files.
Unknown File Types
Some
fragments of data or corrupted files can also be mistakenly interpreted to be
another type of file. Sometimes, file fragments will show up as other file
types. These typically can be ignored as they are not valid files. If the file
matches other properties of a file you are looking for, you can try renaming the
file type to the desired file type.
In some cases, corrupted JPGs will be recovered as MPO files. If you did not make MPO files in your camera, you can sometimes rename the MPO files to JPG files and they will open anyway.
