Store a file content and write it to an other one

[GordonNT]

Hi,

I am trying to create a script that could read a file, store its content (in a txt file for example) and then write it to a new file ?

 

I tried this but it does not work, and strangely, the new file is bigger than the original :

 

#include <File.au3>

local $hFile = FileOpen( "C:\Users\Moi\Desktop\image.png" )
local $f = fileRead( $hFile )

_FileCreate( "C:\Users\XXX\Desktop\file\image.png" )
FileWrite("C:\Users\XXX\Desktop\file\image.png", $f)
FileClose($hFile)

I could be wrong but I do believe that FileOpen will not read a .png image file.

so, how am I supposed to do ?

If you are using .png why are you not simply copying the file from one place to another?

I would like to transfrom the file to string, so I can store this string in a file. Then I can use this string to recreate the file

 

Well, it's not really clear but I hope you can understand

Nope, not a bit. What format, simple text or something else? What kind of file? To what end? Perhaps there is a better way? 

The more you provide the better able we are to assist: "I want to convert .png to text and then back" is a whole lot more difficult to assist with than "I want to convert an image to Base64 for use in program XYZ, then convert it back because abc".

What i want to do is :

 

I have a file (X) and I want to convert it to a txt one (Y)

 

The txt file will be stored on the desktop

 

We remove X

 

Later, we read Y and create X

Again, my question is what does converting it to text gain you in the scope of your process? Why not move the file, then move it back, if it will not have changed?

There are plenty of threads on the forum about converting images to Base64 or some other means - try the forum search function and you will no doubt find some - although I am not aware of any for just converting to flat text. It seems wholly inefficient, hence the questions; I am willing to bet there is a better way to accomplish what you are after.

I convert to image in order to net let the picture accessible

Let's say that my goal is to "hide" some pictures in a txt file

I have an other question, why is my txt file (Y) is bigger than the image (X) ?

[JLogan3o13]

For your question: (txt != image) Not sure why you would expect two different ways of representing an object to be the exact same size.

For your goal, would not setting permissions on the file, setting it to hidden, or setting permissions on the folder in which it resides, be a much simpler and best practice way to accomplish your task? Any time you convert a file from one format to another and then back again you risk corruption; which requires that much more logic to accommodate those potential issues. If all you want to do is prevent/limit access, there are built-in tools for doing just that.

Thanks for all

The issue with Windows permissions is that you always be able to get around them

Anyways, i'll just store those images to

@LocalAppDataDir

and it should be ok

Thanks again

As I said, if you are dead set on converting, a quick search of the forum (or Google) will show you some threads where this has been done - although not as flat text. Good luck in your endeavors.

Also, as you post in the future, please don't quote whatever the person last said. Most of us remember what we said (we were there when we said it) and it needlessly pads the thread

I did a similar thing but it was for video, and it grabs the first, say 700kb and moves them to the end of the file, and rename it without extension, so even if you give it an extension, it won't open because the file is all "messed up". If you want I can post something that is close enough to what you ask.

The idea is to hide files, not full encryption so no good for sensitive data, but enough to most people not being able to figure out what the files are, more info on the page.
