Synchronizing TC's directory with its .cab

[browny]

I tried to use Synchronize tool on TC's installation (Windows 10 1903, 32-bit) and a freshly downloaded beta 2 .cab.
Entered into the .cab, launched the Sync tool, checkmarked by content and ignore date only.
Pressed Compare.
The list of files was the same when Equal files and/or Unequal files were active; and this did not change after syncing.

Both 9.22a and 9.50 b2 have this issue.

Are you sure you have downloaded proper archive file?
When I tried to download 9.50b2 CAB, my browser took download page from cache so I've downloaded totalcmd950b1x32_64.cab instead of totalcmd950b2x32_64.cab and couldn't find any differences too.

[browny]

The name is totalcmd950b2x32_64.cab.
At first the issue was seen in 9.22a, so beta 1 here should make no difference.

It is because TC cannot make the comparison by content in a cab file - therefore you se a "?" for all files when either/or the equal and unequeal button is activated, indicating that no comaprison has taken place - the same you se for comparing two ordinary directories, until the comparison is finished for each file.

It seems to depend on the archive format whether TC can compare by content when synchronizing.

Here it works for:
ZIP, 7Z, RAR, JAR, ARJ, LZH, TAR, TGZ, WIM, CHM, DOCX, XLSX

but not for:
CAB, ACE, SQX, ZPAQ, ICL

Probably your are right.
However, TC can extract files from .cab, and thus comparison by content is possible.

Sure - I wonder why some formats are supported and som are not for the compare by content feature in the Sync tool.

[Usher]

Many archive formats are supported by plugins, so it depends on plugin capabilities.

Probably, but unpacking of ACE is supported internally in TC, and still I cannot use "by content" in ACE archices when synchronizing

Have you tested it with old unpatched unacev2.dll? Forgot about Security problem in unacev2.dll?

I tested it with 64bit TC - it doesn't have a separate unacev2.dl - only the 32bit version does.

EDIT
I have now tested in 32bit TC with version 2.6.0.0 of unacev2.dll from TC 9.0 - still cannot compare contents in Sync tool.

No wonder it doesn't work ;-P

I am not sure what you mean by that?

I have sent my comment before your EDIT, so it's been about trying to run 32-bit dll from 64-bit app.
