OBJ too large and freezes pc - blender

I’m importing a obj creating through Pix4D mapper. The obj file has over 4million faces (400mb) . I can’t edit it without my pc melting and freezing up. Is there anyway to reduce amount of faces or file quality without opening it
I can’t edit the file in blender at all

I accidentally enabled tokenization for a large file, how can I disable it?

I was opening a large .csv file and then a popup appeared saying: "tokenization, wrapping and folding have been turned off for this large file in order to reduce memory usage and avoid freezing or crashing."
I didn't think much of it and enabled it, but now everytime I try to open the file the window freezes. Is there a way to disable tokenization for this file?
I tried decreasing the max tokenization line length to disable tokenization for the .csv file. But, despite that nothing changed and it still kept crashing everytime I try to open it.

Open a large pdf file

I have a large PDF file (3.67 GB). I need some pages of this file. If it could be opened I would get a screenshot of those pages. But the problem is that it needs more memory to be opened. I tried different ways like breaking the pdf or viewing the pdf from server but I was not successful. Would you please let me know if there would be a way to open this large file?
Thanks

Unlinking and saving materials as a copy from .blend file

When we export .fbx file from blender and import them in unity, we get the object without textures and materials. I figured out to get the texture by selecting the image in UV/Image editor sreen and save it as a copy in Image Option.
But I couldn't find any way to save as or copy materials (already attached with object in blender) so that I could attach material to model/game object manually in unity3D.
I have gone through many toturials like baking textures etc. but nothing was helpful. Please note that I do not have to apply Material to model in blender, instead I want the copy of material that are already attached with object, came with .blend file got from internet source.
Tutorial link and explanation will be appreciated.
Have a look at this link
There you get the Information, that only the diffuse color can be exported. Thats more than i expected. Why?
Blender-materials are different than textures. There is no Dataformat for Blender-materials as you have them with textures or objects.
Blender-materials are bound to the internal Data and an full-export seems really hard. Look at blenders Outliner panel and change the view from "All Scenes" to "Datablocks". There you can see how many aspects could be exported. All those would be needed for a full-import on a different program. That is much work, which has not been done so far (as i know).

Killing Adobe Acrobat Viewer Process to free pdf

I have an app that uses a webbrowser window to view several types of documents. One of those document types is a pdf file. After viewing this file and selecting certain criteria in the form it is uploaded to a database. What I would then like to do is more the file to a temp directory that I've already created. Problem being is that a process is still holding that pdf even though I have removed the pdf from the webbrowser. So apparently the problem is that adobe acrobat is running in the background and still retaining the file.
I did fix it.. but not in a way to my satisfaction. Essentially I ran a shell script in the program and killed off AcroRD32.exe. This frees the file and gives me the ability to move. I really dislike having to do this.. not very elegant whatsoever. Is there a better way to handle this situation?

How can i reduce the file size of the ViewPort3D xaml?

I have a 3D max file for a shape. And i convert it to a 3ds file. Then convert it to a xaml file by Zam3D. But the file is too big to load, my computer is crashed by the exception "Output of Memory". What can i do to reduce the xaml file size?
how large is you file? I am working with 3D model files having about 8 MB and are very detailed. The largest I imported successfully had 13.4 MB and the 29 MB-model crashed with the same exception you got but it was not well designed.
To convert 3ds into xaml I am using the Reader3ds of Wpf-Graphics. You avoid the step to convert it twice (through zam3d). The Reader3ds is able to read even large files and you can comfortably use the elements. Next I'm not glad using zam3d, I expect zam3d to put more information to the file than needed. Even the geometry I get is not the same as it was before and lights are added I did not use.
To reduce your xaml you can also try to work with a ResourceDictionary to swap the information to another file and just use it when it's needed.
Hope this helps
