There are several issues here that I am dealing with for this project. #1 The company that we are sending the PDFs to is Windows based, so I am limited as to the formats they can accept (zip and 7z being two of them).
#2 In my testing, I have found that 7z gives significantly more compression. In my test, I took a single PDF that was 17k in size. I made 3 copies of it for a total of 17 x 4 = 68k. Using a traditional zip, I was able to compact these 4 PDFs down into a 33k file (about half). HOWEVER, after compressing it down with 7z, those same 4 PDFs went down to only 8K! That is a SIGNIFICANT difference. #3 I wrote a program we all use that archives the intended file, then transmits the archive to the 2nd party. That way, if they did not get it, I can re-send it from the archive w/o having to try to re-create the data (which may have changed). Also, if there are any issues, I can look at the archive file and determine exactly what they got and then determine if the problem was mine or theirs.

The thing is PDFs are pretty well compressed so you may not gain much disk space back.

Sent: Thursday, March 28, 2013 8:55 AM To: U2 Users List Subject: [U2] Compressing PDFs HPUX, UniData & SB: After a bunch of work, I have a UNIX directory that has a bunch of PDFs. I wish to bundle these PDFs up into a 7zip formatted compressed file. I see that there is a ported version of the Windows version of 7zip for UNIX called p7zip. Has anyone installed p7zip and if so, what else needed to be installed with it? Is it stand-alone or is it dependent on other software packages being loaded first? OR Does anyone have a simple way for UNIX to run the Windows command line version of 7zip against my UNIX PDF directory?
