Can DM script read images with the same extension (like *.mrc) from a folder? - dm-script

I have a bunch of MRC images saved in a folder. I want my DM script to read and process them one by one. Now I just open some of them (like 20 images) at once and use FindNextImage in my script to sequentially process them.
I am wondering if I can define a path and let DM script go to this path to read out the MRC images one by one.

The best way to do this is with the function GetFilesInDirectory. An example of its use was posted with the answer to the following question:
Opening multiple files from folder ...
An example of how to extract the files with a particular file type extension was given in the answer to this question:
How could I open more than one image ...
In particular, have a close look at the method CreateFilteredFileList.

How to Create a Program Which Searches for Values from a .txt or any Text Document in Specific Folders

I am relatively new to programming and want to create a program which can solve a problem that I frequently have.
So here's the background to my short story: I was on a website which hosted many files (We're talking about around 500-1000 small files). I was then like," Oh sweet! I want to have all these things in my hard drive so I know that I have access to them... but am probably not going to use them either way". I proceeded to download all 500-1000 files on that site, but encountered a problem when I looked at the properties of my destination file. Let's say that out of 500 on the site, my computer only had 499 files. Just my luck. I wanted to know what was that one pesky file that slipped right by me and download that file specifically. What I didn't want to do was to delete all the files and then try my luck once more in downloading all the files from the website. On the site, there was no indication of what all files I downloaded, so I was completely in the blue. I could go in Ctrl+C each item, then Ctrl+V into the file manager search bar, but that would be tedious to repeat that 500 times.
Now, what I want to do: I wanted to go ahead and take all of the file names from the website (The file name that I downloaded and the file name that was in my drive are the same), put them all in a simple .txt document or something (The website has multiple unwanted text alongside the text I need, such as:
. If this is not possible to extract the text from the site like this, then I am ok with manually entering the names via copy paste). Then I want the computer to take these values in the document and then search for it in a specific folder path (Note: the actual files are in subfolders within the root folder I want to choose, so the program has to be able to search within multiple folders of the root). Then I want the computer to know if the value in the document, is present as a file. If the file doesn't exist, then I want that value/those values in the document to be displayed as the output. I want this cycle to repeat until all the values have been gone through. The output should list the values that were not present.
Conclusion: You probably now get at what I am trying to do, if you don't, tell me what I need to elaborate on. I really don't care how this program is made (what language or software), I just want something that works... but myself don't know how to create.
Thanks for reading and any response is appreciated!

Here's a solution in Python in case you would like to explore...
Similar to what you described, all files from the website are listed in an Excel file 'website_files.xlsx'
And all files are saved in a folder 'downloaded_wav'. The script will work regardless the files are saved in the root directory or sub-folders.
Then I run below Python script to look for the missing file:
import pandas as pd
import os
path_folder = 'C:\\Users\\Admin\\Downloads\\downloaded_wav'
downloaded_files = []
d,m = 0,0
for path_name, subfolders, files in os.walk(path_folder): #include all subfolders
for file in files:
d+=1
downloaded_files.append(file)
df = pd.read_excel('website_files.xlsx')
for file in df.values:
if file not in downloaded_files:
print('MISSING', file)
m+=1
print(len(df), 'files on website')
print(d, 'files downloaded')
print(m, 'missing file(s) found')
Output:
MISSING ['OLIVER_snare_disco_mixready_hybrid.wav']
3 files on website
2 files downloaded
1 missing file(s) found
No worries; I found a solution by myself using Excel (God, it's powerful!).
Basically, I copied and pasted my values from the website, then used a filter to show the values only with .wav. Then I used a Power Query from the folder to get me a list of all names of files in a folder. Finally, I went ahead and compared the two using a formula:
=IF(COUNTIF(B:B,D,"OK","MISSING")
If you need more elaboration, I'd be happy to help, just reply to this. There might be an easier way, but I personally liked the straight-forwardness of this. You only need Microsoft excel!
EDIT:
For me, I used these two videos which go over the power query and countif function:

In my case, I made my sheet look like this:

How to unzip the same zip file multiple times?

I am developing a zip extractor app for which if i unzip multiple times the same zip file it should extract like myfile-1, myfile-2, myfile-3 something like this .
example : there is sampleproject.zip in my desktop when i unzip it should be like sampleproject, sampleproject-1, sampleproject-2.
Any Suggestions.
Thanks in Advance!
Based on your comment I suggest you unzip your file to a temporary directory and then move its contents into the actual directory, handling any name clashes as you do that. In outline:
Use URLForDirectory:inDomain:appropriateForURL:create:error: to create a temporary directory suitable to unzip into. You should pass your the URL of your destinationPath for the appropriateForURL: parameter; this should give you a temporary directory on the same volume as destinationPath making placing the unzipped items into the right place moves rather than copies.
Unzip into the temporary directory returned by (1)
Now use NSFileManager calls to traverse the temporary directory moving each item found to destinationPath, renaming as needed to avoid name clashes.
Remove the temporary directory.
If you have problems implementing this algorithm ask a new question, show your code, explain your problem, and include a link back to this question so the thread can be followed. Someone will then undoubtedly help you with the next step.

adobe acrobat actions or batch processing - js get paths of all files in a folder

So I would like to create an action that will take a folder, and display/store its contents filenames (as I would later want to manipulate the files on this folder via their filenames). I believe this is achieved via javascript.
I did the ff:
create new action
-> starts with -> A Folder on my Computer
I have no idea what to do next.
Any help would be awesome.
Thanks
A document's path can be accessed via this.path, the file name can be accessed via this.documentFileName. If all you want is a list of paths, you could print them to the console via console.println(this.path);.
There are likely better methods to achieve your objective than via Acrobat's batch processes, but without more detail, it's hard to point you in a direction.

Method to inspect first 4 bytes and rename file extension

I have a large batch of assorted files, all missing their file extension.
I'm currently using Windows 7 Pro. I am able to "open with" and experiment to determine what application opens these files, and rename manually to suit.
However I would like some method to identify the correct file type (typically PDF, others include JPG, HTML, DOC, XLS and PPT), and batch rename to add the appropriate file extension.
I am able to open some files with notepad and review the first four bytes, which in some cases shows "%PDF".
I figure a small script would be able to inspect these bytes, and rename as appropriate. However not all files give such an easy method. HTML, JPG, DOC etc do not appear to give such an easy identifier.
This Powershell method appears to be close: https://superuser.com/questions/186942/renaming-multiple-file-extensions-based-on-a-condition
Difficulty here is focusing the method to work on file types with no extension; and then what to do with the files that don't have the first four bytes identifier?
Appreciate any help!!
EDIT: Solution using TriD seen here: http://mark0.net/soft-trid-e.html
And recursive method using Powershell to execute TriD here: http://mark0.net/forum/index.php?topic=550.0
You could probably save some time by getting a file utility for Windows (see What is the equivalent to the Linux File command for windows?) and then writing a simple script that maps from file type to extension.
EDIT: Looks like the TriD utility that's mentioned on that page can do what you want out of the box; see the -ae and -ce options)
Use python3.
import os,re
fldrPth = "path/to/folder" # relative to My Documents
os.chdir(fldrPth)
for i in os.listdir():
with open(i,'r') as doc:
st = doc.read(4)
os.rename(i,i+'.'+re.search(r'\w+',st).group())
Hopefully this would work.
I don't have test files to check the code. Take a backup and then run it and let me know if it works.

Recommended document structure. File Wrappers? Roll my own?

I'm currently working out the best structure for a document I'm trying to create. The document is basically a core data document that uses sqlite as its store, but uses the Apple provided NSPersistentDocument+FileWrapperSupport to enable file wrapper support.
The document makes heavy use of media, such as images, videos, audio files, etc. with potentially 1000s of files. So what I'm trying to do is create a structure similar to the following:
/myfile.ext/
/myfile.ext/store.sqlite
/myfile.ext/content/
/myfile.ext/content/images/*
/myfile.ext/content/videos/*
/myfile.ext/content/audio/*
Now, first of all I went down the route of creating a temporary directory and placing all of my media in there. Basically creating the paths and file names '/content/images/image1.jpg' as I wanted them to appear in the saved file wrapper, and then upon save I attempted to copy these all into the filewrapper...
What I found was that the files were indeed copied into the wrapper with the file structure I wanted, but when the actual wrapper was saved, these files all magically disappeared.
Great.
So, I trashed my existing solution and tried to use file wrappers instead. This solution involved creating a content wrapper file directory when a new document was created, or loading in a content directory file wrapper upon opening a document.
When an image was added/modified, I created the necessary directory wrappers inside this root content wrapper (i.e. an images directory wrapper if it didn't already exist, or any other intermediary directory wrappers that needed to be created) and then created a regular file wrapper for the media, removing any existing wrapper for that file name if one was there.
Saving the document was just a case of making sure the content file wrapper was added to the document file wrapper, and the document would save.
Well... it did. The first time. However, any attempts to make any subsequent changes i.e add an image, save. Then replace image, save. Did not behave as expected, only showing the image from the first save.
So, my question is... first of all, which of the above approaches is the correct one, if at all, and what am I doing that wrong for them to fail.
And secondly, as I expect to be managing 1000s of images, is using file wrappers the correct way to go about things at all.
With that much media in play, you should likely give your users control over whether the media resides in the document or only a reference to the media is included in the document, and the media resides elsewhere, such as in a library/repository managed by your application. Then they could save out a (potentially many times larger) copy with all references resolved.
You might want to zip/unzip any directory so that users don't get confused trying to attach the document to an email. I believe iWork has been doing this with its document bundles for a while now.
As far as what you are doing wrong, no-one can say, as you haven't provided any code demonstrating what you are doing.
Why don't you create a one-off application that lets you select files on disk and saves those files in a document using a file wrapper? This would let you tackle this functionality without any interference from other issues in your application. Once you understand how to use file wrappers, you can port the code back or just write new code that works.
