If you have made a backup (and set "Backup location" to a zip-archive like "Jan.zip") and then wants to make a "Differential" backup, the process fails.
You get this information:
Starting... Time: 07:28:56 Creating file list, this may take some time. 7-Zip (A) 4.65 Copyright (c) 1999-2009 Igor Pavlov 2009-02-03 Scanning Creating archive D:\Jan.zip\BaseFile.zip Compressing treeinfo.wc Error: move file error D:\BaseFile.zip .tmp1 D:\Jan.zip\BaseFile.zip The system cannot find the path specified. System error: Unspecified error Time: 07:29:16 Elapsed: 00:00:20 Finished
There is a need for a check on the "Backup location" to see if a folder with the desired name can be created.
Otherwise I like the application more and more.
