Abstract
Abstract A method and apparatus for converting long file names to short file names having an eight character prefix and a three character extension. The long file name is examined and separated into a prefix portion and suffix/extension portion. The prefix and suffix portions of the file name are then converted to short file names using the following steps working from right to left: 1) remove lower case vowels; 2) remove lower case consonants; 3) remove upper case vowels; 4) remove upper case consonants; 5) remove single digit numbers; 6) and remove special characters. When the prefix and suffix have been reduced to the desired number of characters, the two portion are concatenated to form a shorten file name.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
120 words
A method, implemented in a computer, for converting a long file name into a short file name, comprising: providing said long file name in said computer for conversion into said short file name; determining a desired size for said short file name; converting said long file name to said short file name by the sequential applications of the following steps: removing lower case vowels until said desired size is reached, removing lower case consonants until said desired size is reached; removing upper case vowels until said desired size is reached; removing upper case consonants until said desired size is reached; removing single digit numbers until said desired size is reached; and removing special characters until said desired size is reached.
Claim 2
Independent Claim
120 words
A method, implemented in a computer, for converting a long file name into a short file name, comprising: providing said long file name in said computer for conversion into said short file name; determining a desired size for said short file name; converting said long file name to said short file name by the sequential applications of the following steps: removing lower case vowels until said desired size is reached, removing lower case consonants until said desired size is reached; removing upper case vowels until said desired size is reached; removing upper case consonants until said desired size is reached; removing single digit numbers until said desired size is reached; and removing special characters until said desired size is reached.
Claim 3
Dependent Claim
34 words
The method of claim 1 wherein the providing step further comprises: detecting a separator mark in said long file name; and separating said long file name into a prefix portion and a suffix portion.
Claim 4
Dependent Claim
24 words
The method of claim 2 wherein said determining step further comprises: selecting said desired size that is different for said prefix and suffix portions.
Claim 5
Dependent Claim
25 words
The method of claim 1 wherein said removing step further comprises: working from right to left to remove the characters from said long file name.
Claim 6
Dependent Claim
27 words
The method of claim 1 wherein said converting step further comprises: concatenating said suffix and prefix with said separator mark when said desired size have been reached.
Claim 7
Independent Claim
134 words
An apparatus for converting a long file name into a short file name, comprising: means for providing said long file name in said computer for conversion into said short file name; means for determining a desired size for said short file name; means for converting said long file name to said short file name by the sequential applications of the following steps: means for removing lower case vowels until said desired size is reached, means for removing lower case consonants until said desired size is reached; means for removing upper case vowels until said desired size is reached; means for removing upper case consonants until said desired size is reached; means for removing single digit numbers until said desired size is reached; and means for removing special characters until said desired size is reached.
