-8.50b3 Compare files inside archives

[gora]

Made a few different types of archives and the same content:

Code: Select all

 1_920.7z (archiver 7-Zip v9.20)
 1_930.7z (archiver 7-Zip v9.30)
 1.ace
 1.cab
 1_4.rar (method RAR4)
 1_5.rar (method RAR5)
 1.zip

Put a copy of these files in different folders. Open the same archives in different folders and compared their contents. The results:

Unequal (shows the symbol "?"): 1_920.7z, 1_930.7z, 1.ace, 1.cab
https://dl.dropboxusercontent.com/u/35142695/NoEqual.png

Equal (shows the symbol "="): 1_4.rar, 1_5.rar, 1.zip
https://dl.dropboxusercontent.com/u/35142695/Equal.png

Why?

? means that TC could not compare the files.
= means that it could compare them, and they were equal.

The problem is that when you have solid archives, you have to unpack them in a specific order. This isn't possible if you have them on both sides, because each one may have a different file order. Therefore this comparison is only supported in some special cases.

1 I compared only identical files 1_920.7z <=> 1_920.7z, 1.ace <=> 1.ace etc.
2 I checked the files 1.ace, 1.cab on TC v8.01 and got "="
3 I did nonsolid 1_920_ns.7z and checked it - got "?"

total7zip.wcx works with sync-compare fine

Sorry, it's currently not supported with internal 7zip unpacker. Please install a plugin if you need this.

7z archives compares well, thank you.

As I remember, TC never compared files in CAB archives by contents, and it is very sad. One of the most popular archives - TC's Install.cab which I sync with TC directory in order to update to new beta.
