They don't have file cabinets here

most home and office furnitures in VN are made by hand. you have it made at the cabinet and lumber yards. that is your best bet.

Hoa Phat supply such metal 2, 3 or 4 drawer cabinets. I don't think you will find cheaper.

Thanks. The one at Hoa Phat is the one I saw before. Seems pretty expensive.

And are hanging file folders to fit it even available in VN? And if they are rarely sold, are they very expensive? But if the cabinets are made by hand, what kind of standard is used for the folders? Do they use hanging file folders? And if so, what size? And do they have to make those by hand too, or are they sold in office supply shops?

This seems ridiculous to me. No standard for file storage.

I posted the wrong link earlier. This is the link that shows you what you get with a file cabinet search on Lazada. Mostly just drawer modules that can't hold files.

I think you are being unrealistic..... I just checked the lowest price from the UK cheapest discount suppliers that I used to use and it is 2.15m for a 2 drawer, compared to the list of 2.75m for Hoa Phat.  Note this is list price - I have always found I can get a discount...   I use the Hoa Phat ones for suspension files, no problem.   

I remember I used to buy plastic crates with hanging file folder rails in western countries. These were very handy, lightweight, cheap, convenient, and they were big enough to hold real documents. But I don't see these here.

Maybe Lotte Mart or Mega Market has those?
