A SFN filename can have at most 8 characters before the dot. If it has more than that, the first 6 must be written, then a tilde as the seventh character and a number (usually 1) as the eighth. The number distinguishes it from other files with both the same first six letters and the same extension. Dots are important and must be used even for folder names (if there is a dot in the folder name). If there are multiple dots in the long file/directory name, only the last one is used. The preceding dots should be ignored. If there are more characters than three after the final dot, only the first three are used. Generally: Any spaces in the filenames should be ignored when converting to SFN. Ignore all periods except the last one. Do not include any other periods, just like the spaces. Use the last period if any, and the next characters (up to 3). For instance, for .manifest, .man only would be used. Commas, square brackets, semicolons, = signs and + signs are changed to underscores. Case is not important; upper case and lower case characters are treated equally.
