I am writing a powershell script which creates a zip file of a local folder:
[System.IO.Compression.ZipFile]::CreateFromDirectory('c:\myfolder\', 'c:\myarchive.zip', [System.IO.Compression.CompressionLevel]::Fastest,$true)
This folder contains an MS-Access database. This database is opened at the same time by another user. I cannot ask him to close this database.
The zip operation fails because the database is locked. Is there a way to bypass this lock and make a copy of the database ?
Thanks a lot
Copy the folder to a temporary place and zip the copy.

I am trying to restore a DB2 database using an encrypted backup file. The backup zip file contains an .lst file, a .ddl file, over 3000 .ixf files, same number of message files and a folder with few .lob files in it.
I have tried using bind # list_file grant public after placing the .lst file and .ixf files in the /bind directory. But the error was that .ixf files could not be opened.
Any help appreciated.
What you have is not a backup (encrypted or otherwise) but the output from the db2move export command execution. Read the db2move documentation to learn how to perform the opposite operation.
Is there any way to create a direct download link to the merged file without creating a temp file on the server in youtube-dl?
youtube-dl -f 255+160 https://youtu.be/p-flvm1szbI
The above code will merge the file and output the merged file.
I want to allow users to directly download the merged file to their computers -- without creating any temp file on my server. Is this possible?
(Creating a temp file and then letting the user download it is already possible.)
When getting a remote ftp file that exists in the local destination
ncftpget says that
local file appears to be the same as the remote file, download is not necessary.
What does appears mean? How does ncftpget check if this is the same file?
It seems that it compares time and size of the file. But does it compare content or at least checksum?
Is there a way to force to overwrite the existing file. Of course other than remove it first.
Is there a way to use the "Copy" command in Powershell to copy a source file to a destination folder but not lock the actual file being copied?
Reason for asking is the file being copied is also an input file for a separate process and if the process starts while the Powershell script is running then it will fail if the Powershell script has locked the input file it uses.
I have a one liner that is baked into a larger script for some high level forensics. It is just a simple copy-item command and writes the dest folder and its contents back to my server. The code works great, BUT even with the switches:
-Recurse -Force
It is not returning the file with an extension of .dat. As you can guess what I am trying to achieve, I need the .dat file for analysis. I am running this from a privileged account. My only thought was that it is a read/write conflict and the host file was currently utilizing it (or other sys file). What switch am I missing? The "mode" for the file that will not copy over is -a---. Not hidden, just not copying. Suggestions elsewhere have said to use xCopy/robocopy- if possible I do not want to call another dependancy- im already using powershell for the majority of the script, id prefer to stick with it....Any thoughts? Thanks in advance, this one has been tickling my brain for a little...
The only way to copy a file in use is to find the locking handle close it then retry the copy operation(handle.exe).
From your question it looks like you are trying to remotely copy user profiles which includes ntuser.dat and other files that would be needed to keep the profile working properly. Even if you did manage to find a way to unload the dat file(s), you would have to consider the impact that would have on the remote system.
Shadow copy is typically used by backup programs to copy files in use so your best bet would be to find the latest backup of each remote computer and then try to extract the needed files from the backed-up copies or maybe wait for the users to logoff and then try.
