This article was previously published under Q142982
Windows supports long file names up to 255 characters in length. Windows also generates an MS-DOS-compatible (short) file name in 8.3 format to allow MS-DOS-based or 16-bit Windows-based programs to access the files.
Windows generates short file names from long file names in the following manner:
For example, "Afile~1.doc" is generated from "A file.doc" because the long file name contains a space.
No short file name is generated from "A_file.doc" because the file name contains less than eight characters and does not contain a space.
The short file name "Alongf~1.txt" is generated from the long file name "A long filename.txt" because the long file name contains more than eight characters.
