Opening 001 files

Did your computer fail to open a 001 file? We explain what 001 files are and recommend software that we know can open or convert your 001 files.

What is a 001 file?

The .001 file extension is often given to files that are from a split file archive or to files that have been created by a backup utility.

When a user creates a copy of his or her hard drive with a backup utility, the resulting file is normally too large to maintain in a single file. Because of this, the file is split down into smaller archive files, with each file being given its own extension. The .001 extension is normally given to the first file of the split file archive. Norton Ghost is one of the programs known to use this file extension for this purpose.

Some digital fax files also may contain the .001 extension.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
