Hi,
As such, there is no particular format for this.
I belong to India's biggest retail company. Initially, I have done this for my department:
1. To make a list of file names on Excel and number them accordingly.
2. You can add up the contents of the file in the same Excel sheet.
3. Place them in the cupboard according to the numbers marked on it.
4. On the inner side of the cupboard, you may paste an index sheet stating that file numbers 1 to 20 are in shelf 1.
5. Mark your cupboards with the numbering.
6. After placing all the files, just keep monitoring any new insertions and place them accordingly.
Dear, it is just a one-time task, and then it would be easy for you and your team even in your absence. Try to make the list clear.
You may categorize files into different heads such as Payments, Assets, Employee Database, clearance forms, corporate connections, traveling expenses, etc.
I am attaching the format for you as we did.
Thanks,
Shweta Jaitly
