We just moved into a new place and have an extra room for an office. The only problem is it's a bit crowded. To open up the room a bit I want to take off the double sliding closet doors and build my desk with a shelving unit into the double closet. Easy. Except, the doors were put in with what I think is bypass door hardware. Confusing. When I went to remove them there wasn't any screws, everything is snapped and riveted.

Is there any way to take these things off without damaging them?

Here are pictures of the hardware:

We may wish to put the doors back in the future and don't want to have to find new hardware.

Any help would be very much appreciated.

Thank You
