I just noticed this recently, I cannot save my blend file.  Cannot open file for writing permission denied.    I have been using Blender for over 5 years and installed it multiple times on multiple computers.  I cannot save on C: drive all of a sudden and I have went into properties on the drive and allowed all permissions.    I can only use blender now as an administrator which is annoying and ridiculous.  I am using windows 10 which it never used to do this before.    All of a sudden, an update or security setting may have done this but I have tried everything--forums, youtube, etc. and nothing fixes this problem.    I know I am not the only one to be having this problem via forums.    This may not be a Blender issue directly but I think your team should look into why this is occurring on multiple computers, I have 3, all around the same time frame-within a week.   This is a Blender windows 10 issue.  I have uninstalled the program, files, and downloaded the installer - like I have multiple times in multiple years - and installed it the same way from the website and it does not fix the problem.    Only Blender is affected - no other programs that I have, photoshop, gimp, paint, etc. ...   Please look into this and thank you.  Matt Mathers

I installed blender for the first time, so I have the latest version, 2.78c.  I played with it for a bit.  Then I discovered I couldn't save my work.  I uninstalled it and reinstalled it.  Rebooted.  Same problem.  After a little testing, I realized I CAN save to my NAS storage drive.  I cannot save on my C: drive.  Any project.  Any folder.  C: always fails.  If I run blender as Administrator, it will save to the C: drive.  But not as my normal userid.  So it sounds like a bug of some kind.  I am running Windows 10.  Bitdefender A/V.  I use OneDrive.  I have a 2TB drive installed.  All clean and purring nicely.  Is there a better way to install it?  Or some change I can make (other than always running as administrator)?    Sounds like a bug - but hopefully there's a proper solution.  Thanks,  Jerry

I was reading a few articles about how people saved their working files and it got me thinking about my own method. I used to save everything as a PSD, but recently I have started saving my working files as TIFF's. I use Windows, so I don't know if it's different for Apple users but with a PSD, all I can see is that "PSD" icon. But a TIFF file shows up as a normal image (that I can edit), so I found it really great when I have a lot of working files for one project and could just quickly preview it without opening the program.  That being said, I am no expert in which method is better. And I know a lot of people here are pretty seasoned users in all things Adobe, so I was wondering what your two cent on the whole topic is?   Is there really any difference to saving it as a PSD or TIFF? Is there something I should specifically know about saving my files as a TIFF rather than a PSD?

I was following a  on how to use the Texture Paint feature on blender so I could paint on a terrain I am modeling. I was successful to paint the whole terrain with beautiful, exuberant vegetation, and crystalline water running through the valley.  So I saved my file, and I went to sleep. But now I've reopened the file and everything seems like I left it yesterday, except that I can see no texture in the terrain... The weird thing is that the textures i used are still there... I don't understand, I barely understand the interface, please help. I'm not even sure if the texture is there or if it was never "saved" or something...     I am now going through the second part of the tutorial for possible answers but I (and hopefully many more) will be grateful for your help.

Using a single 6K texture at only 227kb in size, spikes the memory usage to a crazy 144mb of memory in Blender.  It was brought up in , but closed.  Why can image editors (Photoshop/Gimp/Krita) handle such large images but not Blender?  Whats going on, and more importantly, what can be done to improve it?

When I used Blender, I pressed Ctrl+U (Save Startup File), the folder generated two files, startup.blend and userpref.blend. under C:\Users\hoald\AppData\Roaming\BlenderFoundation\Blender\2.78\config  Can I change this default path into the Blender folder?

How can I copy the path to a folder or a file? The Info Dialog doesn't allow me to copy the information that stands there ...    Is there an easy way to do this?

I opened a blend file and the far right properties panel is completely gone.  The only way I an access it is to change either the top or bottom info bar to the properties but I want it to the generic way, where I have all three panels on my screen. There's no other option to add a side panel that I can find and I'm getting extremely frustrated because when I open a new file, all my windows are there, but this one file just won't open with the freaking side panel!

What websites or other resources do users of Blender have available to them to report bugs or problems with the program?  I would like to get this issue cleared in Q&amp;A format so that we can link new users with bug-report-style questions to this post.

I installed blender on a windows 7 64 bit system.  I opened it one time then went to the tutorials.  in the meantime I had a power failure and when I tried to start blender again I get a dos window that closes itself then nothing.  I reinstalled Blender and get the same thing.  I am going to try to uninstall then reinstall but in the mean time, any other suggestions are welcome.

One of our customers has just found a problem when trying to create a file on the root of the C Drive (C:\), on a Windows 7 Professional PC.  I know they shouldn't be keeping files here, but there is a valid reason in this case, so I've relaxed the security on C:\ by giving the users group users modify permissions.  Before I relaxed the security, the user was receiving access denied, but now they are receiving the message:     An unexpected error is keeping you from creating the file. If you continue to recieve this error, you can use the error code to search for help with this problem. Error 0x80070522: A required priviledge is not held by the client.    for this suggests that it is caused by UAC, but how can I get around this when the user doesn't have admin rights on their PC?

On my current .blend file, when I edit a particular object's origin point and save it, opening the file again resets the origin back to where it was before. I'm unable to save the object with a new origin location. I tried doing CtrlA to set to apply location, rotation, and scale, and then saving it, but upon reopening the object was scaled strangely and the origin once again not in the right location.

When I try to delete the file, using the GUI it says      The action cannot be completed because the file is open in another   program   And using the del /f /q command line it says     Access is denied   I have tried unlocking the file with Unlocker, as well as trying to locate which process is using the file with the Resource Monitor or the Process Explorer, but no locking handle was found in either case.  I am able to rename or move the file, but not to delete it or change its content.

I was experimenting with a file in 2.8 and accidentally saved it. When I opened it back in 2.79 I can't see my model. It disappeared with the error  File written by newer Blender binary.  How can I get my model? I can see my model in 2.8 but nothing in 2.79. I tried to export it  in .obj, but I lost all my modifiers, material and camera setting.

Is there a way I can set create file/folder permissions for a user in Windows 7 without giving delete permission for a folder?  I don't want the user to delete any files in that folder, but he should be able to make new files,rename them, and copy new files to that folder. Is this possible in Windows?

Okay, so I've seen the other answers to this here in Blender Exchange. However, as far as I can figure out those textures were not saved when created in texture paint mode. I added an external texture to my object:   ...then I switched to texture paint mode and the texture changes to a complete black texture:   However if I switch back the texture while in texture paint mode it still keeps my object black:     Is this a lighting problem? Or am I not importing the external image correctly? I have tried packing/saving the image after importing it and putting it on my UV Map and then switching to texture paint mode, but it still occurs.

Using the Nano text editor, I'm trying to save and exit a file.  I already have the file named.  I click Ctrl+X to exit. And then I click Y because I want to save the file. It asks for file to write, I pressed Enter to use the default name because its already named.  The problem is I get this message.   [Error writing /filename: Permission denied]   What am I doing wrong?

I started using Blender couple of weeks ago to edit some of my video clips. Spent quite a while editing this one, and everything worked fine. Video rendered as it should. The whole project consists of a MP4 file with a whole lot of soft cuts. Came back to it a couple days later and now the preview won't show a thing. When I render the scene, it's just a black screen with no sound.  The original file is still working, as well as my other Blender projects. And the weirdest thing is that if I add a new movie clip to the project, the preview works just fine for that clip.  Can anyone guess what might have caused this? I've googled like crazy and haven't found anything helpful.
