Hello John,


How many datasheets do you have archived? How do you organize them?

I have about 2000, around 800 mbytes, on my hard drive, plus a lot
od old cd's lying around in heaps. I'm planning to start an official
company archive, where we save a data*** of any part we use on any
design.

I have about 30k files, or 12GB. That's for semiconductors, I
have a smaller but sizable number of component dat*** files.

I figured we'd just create a folder on the server where everybody
dumps pdf datasheets of any part they use in a design. We'd make
sure the weekly dvd backups include this stuff.

If multiple folks are involved, you need a good system.

Mine are organized by manufacturer, then by type

C:\
DATA\
National\
Amps\
LM7301.pdf
etc
Vregs\
LM1117.pdf
etc
and like that.

Pretty good. I keep drive C: set aside for programs and similar
stuff, which means I can wipe it, reformat it or whatever without
affecting my data. My personal data and project files, etc., are
kept in drive D: (data, get it?). This makes it easy to backup,
by copying the entire drive, without wasting space on programs.

Drive E: is Engineering, for all my datasheets. My structure is,

E:\Companies-Semi\company-name\part-number_rev.pdf and etc.
I also have "app-note" and other folders for each company.

I haven't subdivided the datasheets under category, because many
parts defy categorization, and because that would have become a
difficult time-consuming step in saving the files. But it would
make it easier to find things. Right now I have to remember the
part number. I use Window search (browsing on E:\Companies-Semi)
typing in a piece of the partnumber, so I quickly get lists of
all the second source datasheets, different revs, etc.

Put symbolic links in the relevant subdirs. They're references to the
file, which stays where it is, and don't take up much room. You might
even have all the files in a single repository and spread the links
around in the cataloguing tree. The downside is if you [re]move a file
you'll have to find and remove or change the links.
