.003 File Extension
File TypeSplit Archive Part 3 File
What is a 003 file?
Third part of a split archive created by file splitter and combiner programs; contains the data sequentially following the data stored in a .001 and .002 file; may also have corresponding files with the extensions ".004," ".005," etc. depending on the file size.
File splitting and combining utilities are useful for dividing large files into smaller pieces that make tasks such as emailing large files more manageable.
NOTE: While the ".001," ".002," ".003". extensions are commonly used, not all of them use the same file format. Therefore, be sure to check the software that originally created the file.
