Ultra-compressed .7z files are completely inaccessible on an NAS drive

Hello,

This problem has evaded all solutions offered by me and by my company's technical support.

I am about to move to a new work computer. In order to facilitate this move, I wanted to move as many files onto my shared network drive that I have with the company. Before I sent them over the company network, I thought it would be a good idea to compress them to allow for a quicker transfer and to reduce the use of resources on the shared drive.

The that end I used 7zip to compress 4 folders, each into their own archive, using these settings.

These are not the standard settings for 7zip. The compression settings that 7zip defaults to are theses.

So once all of the files were compressed and ready to go, I copied them onto my shared network drive as shown here.

I then decided to remove the files from my local drive because they would just slow the mandatory company backup process that is required for all laptop moves. At this point, the only copies of these files now existed on the shared drive (they aren't in the recycling bin either).

Later on, I found I needed to access an item that I had stored in one of the archives. I went to the P drive and clicked on the archive that contained the file. I got this message.

I then tried to open it with all of the applicable archive programs and got similar error messages.

Then I tried to copy it from the shared drive back onto my local machine and I got this message.

This is telling me that I need permission from MYSELF to access MY files (I am lyonste).

I got similar results for all of the other files that used the special compression settings I provided.

All of these files were accessible on my local machine, but once placed onto the shared drive, they became untouchable.

This is where things get interesting. I tried compressing another folder WITH STANDARD 7ZIP COMPRESSION SETTINGS. This time, the archive was fine. I was able to manipulate it on the shared drive and copy it back and forth between machines.

I have tried other tricks too. For example, in cmd, I tried using robocopy to copy over the archive files to my local machine. No luck.

I'd really like these files back. Does anyone know of a way to get these files back onto my local machine?

Oh dear, thats one difficult situation you're in. I'll try and help to the best of my abilities.

From what I see, that error message is because you tried to double-click. Have you tried extracting out the data instead?

The errors are also due to permission settings. I see that you're using domain account. So do you have admin rights? Set the permission to your own domain account under the security tab when you right click and choose properties.

If I try to extract with WinRAR, I get this message.

If I try with 7zip, I get this message.
Ultra-compressed .7z files are completely inaccessible on an NAS drive-pdrive6.png

Unfortunately, this is an enterprise environment. I have admin rights on my own laptop, but I don't know if this applies to these files. Regardless, I created these files and the error message says I need permission from myself. Tech support in the company wasn't able to access these files either.

Okay, then right click on the zip program and run as Administrator. Was thinking if its the program that require administrator, not your files. Then again, you did the test with normal compression and it seems alright. Puzzling.

Maximum Path Length?

I was reading some comments the other day.

People were having problems extracting files from archives.
The cause in that case was that the extracted filename (including the Path) exceeded the standard maximum path+filename length.

Might be possible, but i doubt so. The error message would differ from what was shown in the screenshot.

I tried running the 7zip file manager as administrator. I have permissions to do so, but even in this case, the file on the shared drive cannot be touched. I can't even calculate a checksum or "test" the archive. I can't change permissions on the file. Nothing.
