how do you goys manage your ideas and resources in general?
For ideas I use paper, small sheets usually which use to pile up on my desk. At times they get sorted and some thrown away.
If an idea grows into a design it goes to a folder (a real one, still working with paper).
If it seems to have potential and I continue to work on it it will grow as an electronic document from that time. Usually plain text files, though, in the past this was the only format which I could use everywhere.
Resources as in graphics, sound files, sheets and statistics are all electronic in a more or less ordered, well, file dump or so. Sometimes I find stuff in there, if I remember it
I've lost surprisingly little in the past 20 years, but I lost some things that I really miss. The really hard task is to find something in all the backup media that I have ... and at times the problem was to actually have a device to read the old media - and if that works, a program that can read the old file formats.
It got better though since file formats became less architecture dependent and have become longer lasting.
Paper and pencil. Works always and everywhere.
