I am trying to find the specification of a reqif archive file (reqifz). Such an archive is used to transfer multiple reqif documents and "external" objects if i understand correctly. Can anyone point me to how such an archive is structured?

I uploaded files to LiveResponse library using https://github.com/MicrosoftDocs/microsoft-365-docs/blob/public/microsoft-365/security/defender-endpoint/live-response-library-methods.md API.
I overwrite specific file in mistake (and I have no local backup of this file), How can I recover the content of the file from the LiveResponse library before the overwrite?
When I get the list of the library files using GET /api/libraryfiles I got:
{"#odata.context":"https://api.securitycenter.microsoft.com/api/$metadata#LibraryFiles","value":[{"fileName":"script.ps1","sha256":"8b0....f1c63abad95d6bda","description":"1","creationTime":"2022-08-08T15:45:05.170374Z","lastUpdatedTime":"2022-08-08T15:45:05.170374Z","createdBy":"MyUser","hasParameters":false,"parametersDescription":null}
...
And I dont see any indication about the file history etc.
I'm looking for a tool that can extract files by searching aggressively through a ZIP archive. The compressed files are preceded with LFHs but no CDHs are present. Unzip outputs an empty folder.
I found one called 'binwalk' but even though it finds the hidden files inside ZIP archives it seems not to know how to extract them.
Thank You in advance.
You can try sunzip. It reads the zip file as a stream, and will extract files as it encounters the local headers and compressed data.
Use the -r option to retain the files decompressed in the event of an error. You will be left with a temporary directory starting with _z containing the extracted files, but with temporary, random names.
I know this has been asked (in other question as well as) here, which are exactly my cases. I have downloaded (via ADF) a zip file to Azure Blob and I am trying to decompress it and move the files to another location within the Azure Blob container.
However having tried both of those approaches I only end up with a zipped file moved to another location without it being unzipped.
Trying to understand your question - Was your outcome a zip file or the folder name has .zip on it? It sounds crazy, let me explain in detail. In ADF decompressing the zip file using copy activity creates a folder(which has .zip on its name) which has actual file in it.
Example: Let's say you have sample.txt inside abc.zip
Blob sourcepath: container1/abc.zip [Here abc.zip is a compressed file]
Output path will be: container2/abc.zip/sample.txt [Here, abc.zip is the decompressed folder name]
This is achieved when the copy behaviour of sink is "none". Hope it helps :)
I need a microcontroller to read a data file that's been stored in a Zip file (actually a custom OPC-based file format, but that's irrelevant). The data file has a known name, path, and size, and is guaranteed to be stored uncompressed. What is the simplest & fastest way to find the start of the file data within the Zip file without writing a complete Zip parser?
NOTE: I'm aware of the Zip comment section, but the data file in question is too big to fit in it.
I ended up writing a simple parser that finds the file data in question using the central directory.
I am using Minizip API to zip and unzip file to and from my archive. I have a requirement to delete the zip entry from the zip as soon as i extract it.
if the zip archive has multiple zip entries , i am able to delete a particular zip entry soon as i extract it and then able to zip archive with the remaining zip entries. i am able to achieve this using a temp zip .
But when i have a single file inside the zip archive, i am only able to delete the zip after complete extraction....Can there be a optimize way for this situation where i can extract and delete the zip entry in chunks. there is no direct API's in minizip to delete, i am using raw write and read.
Thanks in advance,
JP
No, there is no way to delete part of a file in a ZIP archive, short of extracting the whole file and archiving the part you don't want. (Which doesn't make sense here, since you're already trying to extract the file!)
