TC7 RC1 - Access denied when trying to overwrite r/o file

[Jonathan]

Hello,

after installing RC1 version whenever I try to copy a file (which exists in a .rar file) that will try to overwrite a read only file in the other pane (a normal directory), I get a dialog box with the following text:

Access denied on file
............
Skip Cancel Rename

Up to TC7 pb4 the normal dialog box appeared with all the options (overwrite, overwrite all, overwrite all older, skip, cancel, rename, etc.)

Has anybody else noticed this behaviour?
I haven't changed any of my settings. Reverted to pb4 and the dialog box returned back to "normal".

Issue confirmed for T.C. 7rc1.

Trying to extract 5 files from a ZIP-archive to a target folder where each file existed and was read-only (nasty me ), I encountered the issue which Jonathan described when extracting from a RAR-archive:

There was no option to overwrite the read-only files.

Tested the same using T.C. 6.56 and T.C 7.0pb4:
Got the option to overwrite all read-only files.

To avoid misunderstandings:

As far as I can tell the problem only occurs provided
+ you extract files from an archive (RAR/ZIP/etc)
+ into a folder where at least 1 of the files exists and
+ this file has got the R/O attribute
+ (Note: hidden/system files will be overwritten).

Copying from folder A to folder B overwriting R/O files and or Hidden/System files in folder B is not a problem. After giving the usual confirmations it will work.

Confirmed as described by karlchen.
The same problem exists with "synchronize dirs" function (trying to overwrite R/O files with files extracted from an archive).

Confirmed here too - as described by karlchen

Hi, folks.

Thanks for checking Synchronize Dirs, too.
Last night, I was simply too tired to remember that Synchronize Dirs even existed.

Kind regards,
Karl

Totally confirmed...

On my system I get a "Confirm file replace" dialog.
So it seems to work for me.
Too bad this dialog has no "Overwrite older" option:
this woult speed up the copy process...
Not a TC issue tough, it's WinRAR that's lacking this option !

Hi, Bob.

Thanks for your report.

Provided you used T.C. 7.0rc1 and external WinRAR, I think this limits the problem to unpacking using the T.C. internal unpackers, right?

Karl

[bop sprengers]

Yes, it's a problem with the internal (un)packer.

[petermad]

It also affects packer plugins like sqx !

It's because of this fix:

16.03.07 Fixed: CAB unpack: Didn't detect when target file already existed, but was opened with deny-write rights

I will try to distinguish between the two situations of read-only attribute and deny-write rights. In the first case, overwrite is indeed possible, but not in the second case.

Fixed in TC7rc2

Thanks for checking!
