I have a hard time differentiating these files, maybe understanding the acronyms could help.

If I'm right .ped is from pedigree and .bed is a strange way to say 'binary-pedigree'. The others are obscure.

It sounds like these files were generated from plink? There is a huge list of file formats here: https://www.cog-genomics.org/plink/1.9/formats that I found via googling:

.bed (PLINK binary biallelic genotype table)
.ped (PLINK/MERLIN/Haploview text pedigree + genotype table)
.fam (PLINK sample information file)

More info in the link

Yes, thank you, but my question is about the abbreviations. Like .txt is for text, .csv is for comma-separated values, .fam is for ??? (I mean: it is a really bad abbreviation for "PLINK sample information file")

If I have to guess, .fam stands for family, whereas .bim might be something along the line of binary map file (map file is the SNP coordinate mapping)

Ah right I see your question now. To be honest, does it matter? As long as you have a list of the outputs, you can find what you're looking for
