Lost a lot of work zipping a program

[BKulpa]

I just finished a nice program this morning which I've been working on for the last 2 days. The program was written in V4.1 offline using a step model.

I had a question for our local rep so he asked me to zip a copy of the program and the cad file and e-mail it to him.

I did that then copied the program to the network using explorer, to run it on the machine.

When I opened the program only a small portion was there; so I went back to the offline seat to re-save it to the network. Again only a portion of the program remains.

It seems as if when I zipped the file everything reverted back to the date the file was created; so I lost the work from yesterday and this morning.

Has anyone ever seen this before?

I take it you had no backup of the program before you zipped it. I don't use the 4.x version but never had a problem with zip in 3.5

Are you sure you didn't save a copy in one location and then save to another after that? I've done that in the past.

No problem in the past

I've used versions from 3.2063 to 4.1 and never encountered this before.

I searched my hard drive, checked the zip file, and everywhere else I can think of. Every copy of the program is the same, 2 days lost.

I think I'm going to cry!

Is there an auto save copy ?
