I created a C# snippet that calls 7zip (7za) to add a list of files to a zip archive. Problem is multiple files in different directories have the same name, so 7zip either complains about duplicate names or replaces the first file with the second only storing the last added. I cannot recursively scan a directory which would allow duplicates.
Is there a way to force 7zip to store the directory, or in ASP.NET MVC 3 C# to create zip files with duplicate file names when not considering the full path?
The path to our image is the GTIN number broken up by every five digits. The last five are the name of the image.
G:\1234\56789\01234.jpg
G:\4321\09876\01234.jpg
G:\5531\33355\01234.jpg
These would fail to all store in a 7zip archive correctly.
You can use SevenZipSharp: http://sevenzipsharp.codeplex.com/ a wrapper around 7zip. You will have full control from code.
We managed to get multiples in the same archive by creating a file list that doesn't contain leading backslashes, then running the application from the directory containing them:
1234\56789\01234.jpg
4321\09876\01234.jpg
5531\33355\01234.jpg
It solves it for now. Anyone with a better idea?

I'm trying to figure out how to perform the following steps within NiFi.
Obtain listing of directories from a specific location e.g. /my_src (Note the folders that will be appearing within here will be dated e.g. 20211125)
Based off of the listing obtained I need to sort the folders by date
For each folder then I need to GetFile from that directory
Then sort those files by their names
I am stuck at step 1 on finding a processor that pulls the directory names. I only see GetFile and List file.
Reason for this is that I need to process the folders based on the oldest to newest.
I would expect to be using a regex pattern to locate the valid folders that match the date format and ignore the other folders. Then with those values found pass them along sorted to another process that would get files from that path location, which GetFile does not seem to allow me to set dynamically.
Am I to approach this process differently within NiFi?
I have a folder that has around 400 subfolders each with ONE .jpeg file in them. I need to get all the pictures into 1 new folder using SSIS, everything is on my local (no connecting through different servers or DBs) just subfolders to one folder so that I can pull out those images without going one by one into each subfolder.
I would create 3 variables, all of type String. CurrentFile, FolderBase, FolderOutput.
FolderBase is going to be where we start searching i.e. C:\ssisdata
FolderOutput is where we are going to move any .jpg files that we find rooted under FolderBase.
Use a Foreach File Enumerator (sample How to import text files with the same name and schema but different directories into database?) configured to process subfolders looking for *.jpg. Map the first element on the Variable tab to be our CurrentFile. Map the Enumerator to start in FolderBase. For extra flexibility, create an additional variable to hold the file mask *.jpg.
Run the package. It should quickly zip through all the folders finding and doing nothing.
Drag and drop a file system task into the Foreach Enumerator. Make it a Move file (or maybe it's rename) type. Use a Variable source and destination. The Source will be CurrentFile and the destination will be FolderOutput
I work as technical photographer. I do a lot of photos of particular parts. Each parts get a folder assigned and then I copy photos to the folder.
I would like the names of files (photos) get a prefix which is folder name. Example:
I take 20 photos of part A1. I copy those 20 photos from SD card to my PC to previously created folder named "A1". I would like those 20 files to have names as follows:
A1(1)
A1(2)
A1(3)
[...]
A1(20)
Is it possible to make it automatic? or do it by one click?
Thanks in advance
If you don't need to preserve the original numbering, it's as simple as selecting all the files in Explorer, pressing F2 (for rename) and typing in the new name. The files will automatically get non-colliding names in the form of "Name (number)".
This respects the ordering you have selected in Explorer, so if you want the index to increment from older to newer files, for example, just sort the files by date ascending.
This can also be used to preserve the original numbering, but only if there are no gaps and if the numbers start from 1. If you sort the files by name and do the rename trick, they will still be ordered the same as before. If there are gaps, they will not be there anymore with the new file names, though.
One more gotcha is that this only works if all of the files have the same extension. If some are jpg and others png, for example, each extension will get its own numbering.
If this isn't good enough, you'll either have to use a script, which is a bit more advanced, or some tool that helps with batch renaming. My favourite has been Total Commander for a long time - in TC, this is as simple as selecting the files you want to rename, pressing Ctrl+M, and changing the file name to something like A1 ([N]).
I am organizing a large Windows folder with many subfolders (with sub folders, etc...), in which files have been saved multiple times in different locations. Can anyone figure out how to identify all files with duplicate names across multiple directories? Some ways I am thinking about include:
A command or series of that could be run in the command line (cmd). Perhaps DIR could be a start...
Possibly a tool that comes with Windows
Possibly a way to specify in search to find duplicate filenames
NOT a separate downloadable tool (those could carry unwanted security risks).
I would like to be able to know the directory paths and filename to the duplicate file(s).
Not yet a full solution, but I think I am on the right track, further comments would be appreciated:
From CMD (start, type cmd):
DIR "C:\mypath" /S > filemap.txt
This should generate a recursive list of files within the directories.
TODO: Find a way to have filenames on the left side of the list
From outside cmd:
Open filemap.txt
Copy and paste the results into Excel
From Excel:
Sort the data
Add in the next column logic to compare to see if the current text = previous text (for filename)
Filter on that row to identify all duplicates
To see where the duplicates are located:
Search filemap.txt for the duplicate filenames identified above and note their directory location.
Note: I plan to update this as I get further along, or if a better solution is found.
I am having a huge .tgz file which is further structured inside like this:
./RandomFoldername1/file1
./RandomFoldername1/file2
./RandomFoldername2/file1
./RandomFoldername2/file2
etc
What I want to do is having each individual file extracted to standard output so that I can pipe it afterwards to another command. While doing this, I also need to get the RandomFoldername name and file name so that I can deal with them properly from within the second command.
Till now the options I have are
to either extract all of the tarball and deal with the structured files that I will be having, which is not an option since the extracted tar doesn't fit into the hard drive
Make a loop that pattern match each file and extract one file at time. This option although that solves the problem, is too slow because the tarball is sweeped each time for only one file.
While searching on how to solve this, I've started to fear that there is no better alternative to this.
Using tar the tool I don't believe you have any other options.
Using a tar library for some language of your choice should allow you to do what you want though as it should let you iterate over the entries in the tarball one-by-one and allow you to extract/pipe/etc. each file one-by-one as necessary.
