An XML language for describing file attributes of a directory tree?

阅读更多关于 An XML language for describing file attributes of a directory tree?

That is, it should say something like: File name is: abc.txt Last modification date is: 2009-12-31T01:23 Read-only attribute is: True Hidden attribute is: False The listings will persist for years in a long-term archive, so the language should be self-evident to an information archaeologist of the future. The language should be able to describe the most commonly-used file attributes of common PC

I'd like to be able to set these programmatically. How do I programmatically set a file tag and other file attributes using Delphi (I have Delphi 2010 Pro)? 回答1: Tags in JPEG files are stored as IPTC keywords. There are a few libraries available for reading and writing those, if that's what you're asking for.

问题 I'm trying to set flag that causes the Read Only check box to appear when you right click \ Properties on a file. Thanks! 回答1: Two ways: System.IO.FileInfo fileInfo = new System.IO.FileInfo(filePath); fileInfo.IsReadOnly = true/false; or // Careful! This will clear other file flags e.g. FileAttributes.Hidden File.SetAttributes(filePath, FileAttributes.ReadOnly/FileAttributes.Normal); The IsReadOnly property on FileInfo essentially does the bit-flipping you would have to do manually in the

问题 I'm trying to extract some version information from a DLL using python. I read this question: Python windows File Version attribute It was helpful, but I also need to get the 'Assembly version' from the DLL.

阅读更多关于 Get File Creation Date Over HTTP

问题 Given a file on a webserver (e.g., http://foo.com/bar.zip -> only accessible through HTTP), is there any way to get the date attributes (e.g., date [created, modified]) without downloading the entire archive in the first place? Right now, I download the archive and read the attributes programmatically. Trouble is that the archive is dozens of MiB so it seems like a waste of resources to download the entire thing and end up reading off just a couple of bytes of information. I realize that

Keeping file attributes on a copy

I found the following question on Stack Unix, but I was wondering if there was a way for me to do this in Python. 回答1: If you look at the documentation for shutil , you'll immediately find
