Do you really need everything in the files?
Maybe you have already done this, but worth thinking about if not.
I have just thinned out the material in my office files. Questions I asked myself:
- Can I get another copy of this (electronic or paper) easily if I need it?
- Has this been replaced by a newer version?
- Is the project still running?
- Am I responsible for this area, or just keeping it 'for information'
In my work, I am not responsible for filing 'compliance' documentation (signed contracts etc), so it is relatively easy to cull.
At home, at financial year end, I put all financial documents for the previous year in an archive box, marked with the year, and destroy the archives over 5 years old (tax record keeping guidelines). I also review the 'warranties & manuals' folders and throw out anything expired or no longer in use.
