My conclusion is that I do not have a stable backup. On this backup #3 I can click on 3_Czip and this folder opens as normal and has subfolder arrows. I next ran backup #3 and the program calls it a Diff and when BU completed it shows size 1,124,858. However, sometimes the zipped folder would start throwing errors and not let you open it, the most common issues are compressed zip folder is. At the same time a green bar runs across the top of Win Explorer but after some 48 minutes nothing happened (I thought maybe win-10 had to 'index' the folder) so I closed the error message box. They are like folders but with properties of files, which means you can download/upload zipped files easily and make multiple-file transfer much more convenient. The same for 2_Czip that shows a file size of 90,204,672 KB (Full backup) yields the following error message 'The compressed (zipped) folder (path) 2_Czip' is invalid.' Same thing about the missing subfolder arrow. While in windows explorer I clicked on the BU folder 1_Czip that shows a file size of 79,811,129 KB (Full backup) yields the following error message 'The compressed (zipped) folder (path) 1_Czip' is invalid.' Also there is no subfolder arrow indicating that subfolders exist. I am running Win-10 (started in January) using BU4ALL 6.6. If you have Solved: contains characters in its name that compressed zipped folders cannot store then we strongly recommend that you Download (Solved: contains characters in its name that compressed zipped folders cannot store) Repair Tool.
