I would like users to download a zip file and I have the following code.
<a href="directory/fileName.zip" download>DOWNLOAD</a>
However, when I test it out, the file downloads instantly and when I try to open it, I get the unsupported format error. On localhost, it downloads instantly but the zip file successfully opens.
I am on MacOS and have git lfs installed if that is important. Any help would be greatly appreciated. Thank you.
I tried renaming the file so that there are no spaces in its name, tried to separately compress the directory to be zipped.
When I use AppWeb+esp for uploading files, I just got a file with suffix .tmp. (Use UploadAutoDelete and UploadDir)
How can I find the file I uploaded with it’s own name and which directory it will be?
Sincerely
Ziyang
I want to run a notebook that uses many header files defined in the directory. So basically I want to upload the entire directory to Google Colab so that I can run the notebook. But I am unable to find any such options and only able to upload files not complete folders. So can someone tell me how to upload entire directory to google colab?
I suggest you not to upload them just in Colab, since when you're restarting the runtime you will lose them (just need to re-upload them, but it can be an issue with slow connections).
I suggest you to use the google.colab package to manage files and folders in Colab. Just upload everything you need to your google drive, then import:
from google.colab import drive
drive.mount('/content/gdrive')
In this way, you just need to login to your google account through google authentication API, and you can use files/folders as if they were uploaded on Colab.
EDIT May 2022:
As pointed out in the comments, using Google Drive as storage for a large number of files to train a model is painfully slow, as described here: Google Colab is very slow compared to my PC. The better solution in this case is to zip the files, upload them to colab and then unzip them using
!unzip file.zip
More unzip options here: https://linux.die.net/man/1/unzip
You can zip them, upload, then unzip it.
!unzip file.zip
The easiest way to do this, if the folder/file is on your local drive:
Compress the folder into a ZIP file.
Upload the zipped file into colab using the upload button in the File section. Yes, there is a File section, see the left side of the colab screen.
Use this line of code to extract the file. Note: The file path is from colab's File section.
from zipfile import ZipFile
file_name = file_path
with ZipFile(file_name, 'r') as zip:
zip.extractall()
print('Done')
Click Refresh in the colab File section.
Access the files in your folder through the file paths
Downside: The files will be deleted after the runtime is over.
You can use some part of these steps if your file is on a Google Drive, just upload the zipped file to colab from Google Drive.
you can create a git repository and push the files and folders to it,
and then can clone the repository in colaboratory with the command
!git clone https://github.com/{username}/{projectname}.git
i feel this method is faster.
but if the file size is more than 100 mb you will have to zip the file or will have to add extentions to push it to github.
for more information refer the link below.

The best way to approach this problem is simple yet tricky sometimes.
You first need to compress the folder into a zipped file and upload the same into your google drive.
While doing so, Make sure that the folder is in the root directory of the drive and not in any other subfolder!. If the compressed folder/data is in other subfolder, you can easily move the same into the root directory.
Compresses folder/data in another subfolder often messes with the unzipping process when you will be specifying the file location.
Once you did the afore mentioned tasks, enter the following commands in the colab to mount your drive:
from google.colab import drive
drive.mount('/content/gdrive')
This will ask for an access token that can be generated by clicking on the url displayed in the output of the same cell
!ls gdrive/MyDrive
Check the contents of the drive by executing the above command and ensure that your folder/data is displayed in the output.
!unzip gdrive/MyDrive/<File_name_without_space>.zip
eg:
!unzip gdrive/MyDrive/data_folder.zip
Executing the same will start unzipping your folder into the memory.
Congrats! You have successfully uploaded your folder/data into the colab.
zip your files zip -r file.zip your_folder and then:
from google.colab import files
from zipfile import ZipFile
with ZipFile(files.upload(), 'r') as zip:
zip.extractall()
print('Done')
So here's what you can do:
-upload the dataset desired folder to your drive
-over colab, mount the drive wherein this
"from google.colab import drive
drive.mount('/content/gdrive')"
automatically shows up and you just need to run it
-then check for your file over the Files section on the left-hand side (if folder not visible try refreshing, also there should be a drop-down arrow next to it where you can check all the files under the folder )
-left-click over the folder wherein you get a COPY PATH option
-paste the copied path over the desired location in your colab
Hello everyone I'm trying to unzip a USDZ file, modify a texture, and then zip the USDZ file again, but it breaks.
Is there any special way to zip the file back? Even if I decompress and compress again it stops working and has different file size.
I'm using no compression and no encryption to zip the file. One thing I have noticed is that the attribute "Needed to extract" for the USDZ file is "2.0 or later" while my new zip file value is "1.0 or later". Also the files in the original USDZ zip have some extra fields I cannot read or add to my new file.
What could be happening? Any help would be appreciated.
Unzip usdz file
To unzip a usdz file in macOS use the following steps (if you don't have Mac, use a Hackintosh):
In Finder change the extension of .usdz file to .zip.
Uncompress .zip file by double-clicking it.
Open unzipped directory and change the .png textures of your model.
Open and edit .aiff, .caf or mp3 audio files, if any.
You can even import a binary .usdc file in Maya 2023 for animation.
Create usdz file again
Make sure that the latest Xcode version is installed (now Xcode 14.0).
To convert a content of unzipped folder (binary usdc file and its textures) back to usdz file format again, use the following command in Terminal.app:
usdzconvert ~/Desktop/file.usdc -diffuseColor Grammophone_Albedo.png
-metallic Grammophone_Metallic.png
-occlusion Grammophone_AO.png
-normal Grammophone_Normal.png
-roughness Grammophone_Roughness.png
And here's an additional info about usdzconvert command for Xcode 14/13/12/11/10.
To pack my modified USDZ file back, I used the tools provided here: https://github.com/PixarAnimationStudios/USD (usdzip) which works in Windows and Linux.
When I connect to a web-site that is using Silverlight, my understanding is that the "XAP" file is downloaded to C:\Users\ "UserName" \AppData\Local\Temp folder (under windows Vista).
There are few sites that I know that are using "XAP" files but I don't see a "XAP" file in this folder. Any ideas?
I think I found the answer. It just gets downloaded to the logged-in user's temporary internet files folder.
