I have a zip file with a few pdf files. If I double-click on the first pdf, adobe reader opens the file. OK. I keep adobe reader open with this file. If I now double-click on the second file, the file doesn't open in adobe reader. there comes an error message "file not found". Can someone confirm this issue?
I tried your case but i dont find any error in opening files. Check the version of 7zip you are using is latest.
I use version 9.27 (alpha). The 1st file opens in adobe raeder. But the 2nd file produces this error, if the 1st file is still open in the adobe raeder.
