Hello, I need to implement something like my own file system. One operation would be the FindFirstFile. I need to check, if the caller passed something like ., sample*.cpp or so. My "file system" implementation provides the list of "files names" as a array of char*. Is there any Windows function or any source code that implements this ...
Hey all, I have a question about how PHP handles filesystem operations. I'm running this code that depends on a file being created before it gets used, and it feels like when I run the code it becomes a race condition - sometimes the it works, the file is created and php code uses it, sometimes it fails. So I was wondering how php han...
Is this possible with php? ...
We have a file system filter driver. It has a feature which encrypts some files. We implemented this feature yesterday, but after shipping the feature, when we reboot sometimes Windows will check the file system by running chkdsk. Has anyone else developing filter drivers encountered this problem? How can we solve this? ...
I am making a protocol, client and server which provide file transfer functionality similar to FTP (among other features). One difference between my protocol and FTP is that I would like to store a copy of the remote server's directory structure in a local cache. The server will only be running on Windows (written in C++) so any applic...
I'm interested to know if there's any method/mechanism to roll my own virtual file system that will run on modern windows. The idea would be that no matter what part of the operating system tried to access files under the directory I "control", all of the operations are filtered through some kind of callback code. If not, is there a fu...
I've got a large folder on an offsite backup machine that gets populated with files by rsync (through deltacopy) every night (running windows xp) from the main work site. I've discovered some annoying folders that cannot be opened, or deleted, or even checked for file sizes. I get the such and such a folder is not accessible, access is d...
I'm using os.statvfs to find out the free space available on a volume -- in addition to querying free space for a particular path, I'd like to be able to iterate over all volumes. I'm working on Linux at the moment, but ideally would like something which returns ["/", "/boot", "home"] on Linux and ["C:\", "D:\"] on Windows. ...
Is it possible to add a custom property to an object that is part of the .NET framework? I know how I would do this if I was just giving a class i'd wrote a property, but what about adding a custom property to the FileSystemWatcher class? I'm loading in the Path I want to watch from an XML file, but also want to add a property to store...
What are some best practises for prototyping a filesystem? I've had an attempt in Python using fusepy, and now I'm curious: In the long run, should any respectable filesystem implementation be in C? Will not being in C hamper portability, or eventually cause performance issues? Are there other implementations like FUSE? Evidently c...
Hi. I am developing fuse fs at python (with fuse-python bindings). What method I need to implement that touch correctly work? At present I have next output: $ touch m/My\ files/d3elete1.me touch: setting times of `m/My files/d3elete1.me': Invalid argument File exists "d3elete1.me": $ ls -l m/My\ files/d3elete1.me -rw-rw-rw- 1 r...
Hi all, I am programming a C# application that checks the last time a file was modified on 3 different servers, one of these being linux. Being a different file system what are the possible ways to check when said file was last modified on the system. I have full access to modifying the server to an extent but I am looking for a number...
I'm using code like the following to check whether a file has been created before continuing, thing is the file is showing up in the file browser much before it is being detected by stat... is there a problem with doing this? //... do something struct stat buf; while(stat("myfile.txt", &buf)) sleep(1); //... do something else alt...
Writing a lightweight file system recovery application, I need to understand how to identify ext/ext/ext/ext4 superblocks on a disk. Googling for a spec, all I found are pages that explain how to use ext4, but none with specs for it, not even for ext3. Yeah, I could read the source code. But the source code wouldn't specify what's supp...
The MSDN has a pretty good example of getting notified when a file or directory is changed. However, I can't find any way to get extra information such as the user/machine name associated with the change notification. For example, I've setup a share X:\Foo from my machine. I would like to log the user/machine names that make changes t...
I have a folder in which continuously new files are being dumped.In Java,what is the best way to detect changes in file-system (ie. a specified folder in which the files are being dumped) and add the newly arrived files to a queue data structure so that i can sequentially process each incoming file. I'm aware of listFiles() function in ...
Hello I'm working on embedded platform (Broadcom's bcm5358u processor with MIPS core), where I need extra partitions for the purpose of further upgrade procedure. The filesystem used is SquashFS, so I modified 'struct mtd_partition' accordingly, which is passed to MTD related code, and I ended up with this: #cat /proc/partitions major ...
Hey! What is the difference between saving a file (e.g. AVI) as a Blob in the datastore to saving it as a normal AVI file on a webserver? Thanks! Joel ...
I am implementing a file browser, in Eclipse RCP, using a TreeViewer. Would it be best to put it in an Editor or ViewPart. I ask because, I need to be able to pass the root path for the browser and do not know of a way to do so with a view. As views are not instantiated directly. ...
I tested this on windows xp. If I do Create a file. Write to the file. Close the file.(Then, the file's LastWriteTime is changed) But if I do Create a file. Set LastFileTime of the file. Examine the time by calling GetFileTime (Then, the file's LastWriteTime is changed) Sleep 20 seconds. Write to the file. Sleep 20 seconds. Close ...
