Upload files to Azure Blob storage by using AzCopy
You can upload files and directories to Blob storage by using the AzCopy v10 command-line utility.
To see examples for other types of tasks such as downloading blobs, synchronizing with Blob storage, or copying blobs between accounts, see the links presented in the Next Steps section of this article.
Get started
See the Get started with AzCopy article to download AzCopy and learn about the ways that you can provide authorization credentials to the storage service.
Note
The examples in this article assume that you've provided authorization credentials by using Microsoft Entra ID.
If you'd rather use a SAS token to authorize access to blob data, then you can append that token to the resource URL in each AzCopy command. For example: 'https://<storage-account-name>.blob.core.windows.net/<container-name><SAS-token>'.
Create a container
You can use the azcopy make command to create a container.
Tip
This example encloses path arguments with single quotes (''). Use single quotes in all command shells except for the Windows Command Shell (cmd.exe). If you're using a Windows Command Shell (cmd.exe), enclose path arguments with double quotes ("") instead of single quotes ('').
Syntax
azcopy make 'https://<storage-account-name>.<blob or dfs>.core.windows.net/<container-name>'
Example
azcopy make 'https://mystorageaccount.blob.core.windows.net/mycontainer'
Example (Data Lake Storage endpoint)
azcopy make 'https://mystorageaccount.dfs.core.windows.net/mycontainer'
For detailed reference docs, see azcopy make.
Upload a file
Upload a file by using the azcopy copy command.
Tip
This example encloses path arguments with single quotes (''). Use single quotes in all command shells except for the Windows Command Shell (cmd.exe). If you're using a Windows Command Shell (cmd.exe), enclose path arguments with double quotes ("") instead of single quotes ('').
Syntax
azcopy copy '<local-file-path>' 'https://<storage-account-name>.<blob or dfs>.core.windows.net/<container-name>/<blob-name>'
Example
azcopy copy 'C:\myDirectory\myTextFile.txt' 'https://mystorageaccount.blob.core.windows.net/mycontainer/myTextFile.txt'
Example (Data Lake Storage endpoint)
azcopy copy 'C:\myDirectory\myTextFile.txt' 'https://mystorageaccount.dfs.core.windows.net/mycontainer/myTextFile.txt'
You can also upload a file by using a wildcard symbol (*) anywhere in the file path or file name. For example: 'C:\myDirectory\*.txt', or C:\my*\*.txt.
Upload a directory
Upload a directory by using the azcopy copy command.
This example copies a directory (and all of the files in that directory) to a blob container. The result is a directory in the container by the same name.
Tip
This example encloses path arguments with single quotes (''). Use single quotes in all command shells except for the Windows Command Shell (cmd.exe). If you're using a Windows Command Shell (cmd.exe), enclose path arguments with double quotes ("") instead of single quotes ('').
Syntax
azcopy copy '<local-directory-path>' 'https://<storage-account-name>.<blob or dfs>.core.windows.net/<container-name>' --recursive
Example
azcopy copy 'C:\myDirectory' 'https://mystorageaccount.blob.core.windows.net/mycontainer' --recursive
Example (Data Lake Storage endpoint)
azcopy copy 'C:\myDirectory' 'https://mystorageaccount.dfs.core.windows.net/mycontainer' --recursive
To copy to a directory within the container, just specify the name of that directory in your command string.
Example
azcopy copy 'C:\myDirectory' 'https://mystorageaccount.blob.core.windows.net/mycontainer/myBlobDirectory' --recursive
Example (Data Lake Storage endpoint)
azcopy copy 'C:\myDirectory' 'https://mystorageaccount.dfs.core.windows.net/mycontainer/myBlobDirectory' --recursive
If you specify the name of a directory that doesn't exist in the container, AzCopy creates a new directory by that name.
Upload directory contents
Upload the contents of a directory by using the azcopy copy command. Use the wildcard symbol (*) to upload the contents without copying the containing directory itself.
Tip
This example encloses path arguments with single quotes (''). Use single quotes in all command shells except for the Windows Command Shell (cmd.exe). If you're using a Windows Command Shell (cmd.exe), enclose path arguments with double quotes ("") instead of single quotes ('').
Syntax
azcopy copy '<local-directory-path>\*' 'https://<storage-account-name>.<blob or dfs>.core.windows.net/<container-name>/<directory-path>'
Example
azcopy copy 'C:\myDirectory\*' 'https://mystorageaccount.blob.core.windows.net/mycontainer/myBlobDirectory'
Example (Data Lake Storage endpoint)
azcopy copy 'C:\myDirectory\*' 'https://mystorageaccount.dfs.core.windows.net/mycontainer/myBlobDirectory'
Append the --recursive flag to upload files in all subdirectories.
Upload specific files
You can upload specific files by using complete file names, partial names with wildcard characters (*), or by using dates and times.
Tip
These examples enclose path arguments with single quotes (''). Use single quotes in all command shells except for the Windows Command Shell (cmd.exe). If you're using a Windows Command Shell (cmd.exe), enclose path arguments with double quotes ("") instead of single quotes ('').
Specify multiple complete file names
Use the azcopy copy command with the --include-path option. Separate individual file names by using a semicolon (;).
Syntax
azcopy copy '<local-directory-path>' 'https://<storage-account-name>.<blob or dfs>.core.windows.net/<container-name>' --include-path <semicolon-separated-file-list>
Example
azcopy copy 'C:\myDirectory' 'https://mystorageaccount.blob.core.windows.net/mycontainer' --include-path 'photos;documents\myFile.txt' --recursive'
Example (Data Lake Storage endpoint)
azcopy copy 'C:\myDirectory' 'https://mystorageaccount.dfs.core.windows.net/mycontainer' --include-path 'photos;documents\myFile.txt' --recursive'
In this example, AzCopy transfers the C:\myDirectory\photos directory and the C:\myDirectory\documents\myFile.txt file. Include the --recursive option to transfer all files in the C:\myDirectory\photos directory.
You can also exclude files by using the --exclude-path option. To learn more, see azcopy copy reference docs.
Use wildcard characters
Use the azcopy copy command with the --include-pattern option. Specify partial names that include the wildcard characters. Separate names by using a semicolin (;).
Syntax
azcopy copy '<local-directory-path>' 'https://<storage-account-name>.<blob or dfs>.core.windows.net/<container-name>' --include-pattern <semicolon-separated-file-list-with-wildcard-characters>
Example
azcopy copy 'C:\myDirectory' 'https://mystorageaccount.blob.core.windows.net/mycontainer' --include-pattern 'myFile*.txt;*.pdf*'
Example (Data Lake Storage endpoint)
azcopy copy 'C:\myDirectory' 'https://mystorageaccount.dfs.core.windows.net/mycontainer' --include-pattern 'myFile*.txt;*.pdf*'
You can also exclude files by using the --exclude-pattern option. To learn more, see azcopy copy reference docs.
The --include-pattern and --exclude-pattern options apply only to filenames and not to the path. If you want to copy all of the text files that exist in a directory tree, use the -recursive option to get the entire directory tree, and then use the -include-pattern and specify *.txt to get all of the text files.
Upload files that were modified before or after a date and time
Use the azcopy copy command with the --include-before or --include-after option. Specify a date and time in ISO-8601 format (For example: 2020-08-19T15:04:00Z).
The following examples upload files that were modified on or after the specified date.
Syntax
azcopy copy '<local-directory-path>\*' 'https://<storage-account-name>.<blob or dfs>.core.windows.net/<container-or-directory-name>' --include-after <Date-Time-in-ISO-8601-format>
Example
azcopy copy 'C:\myDirectory\*' 'https://mystorageaccount.blob.core.windows.net/mycontainer/FileDirectory' --include-after '2020-08-19T15:04:00Z'
Example (Data Lake Storage endpoint)
azcopy copy 'C:\myDirectory\*' 'https://mystorageaccount.dfs.core.windows.net/mycontainer/FileDirectory' --include-after '2020-08-19T15:04:00Z'
For detailed reference, see the azcopy copy reference docs.
Upload with index tags
You can upload a file and add blob index tags to the target blob.
If you're using Microsoft Entra authorization, your security principal must be assigned the Storage Blob Data Owner role, or it must be given permission to the Microsoft.Storage/storageAccounts/blobServices/containers/blobs/tags/write Azure resource provider operation via a custom Azure role. If you're using a Shared Access Signature (SAS) token, that token must provide access to the blob's tags via the t SAS permission.
To add tags, use the --blob-tags option along with a URL encoded key-value pair.
For example, to add the key my tag and a value my tag value, you would add --blob-tags='my%20tag=my%20tag%20value' to the destination parameter.
Separate multiple index tags by using an ampersand (&). For example, if you want to add a key my second tag and a value my second tag value, the complete option string would be --blob-tags='my%20tag=my%20tag%20value&my%20second%20tag=my%20second%20tag%20value'.
The following examples show how to use the --blob-tags option.
Tip
This example encloses path arguments with single quotes (''). Use single quotes in all command shells except for the Windows Command Shell (cmd.exe). If you're using a Windows Command Shell (cmd.exe), enclose path arguments with double quotes ("") instead of single quotes ('').
Upload a file
azcopy copy 'C:\myDirectory\myTextFile.txt' 'https://mystorageaccount.blob.core.windows.net/mycontainer/myTextFile.txt' --blob-tags='my%20tag=my%20tag%20value&my%20second%20tag=my%20second%20tag%20value'
Upload a directory
azcopy copy 'C:\myDirectory' 'https://mystorageaccount.blob.core.windows.net/mycontainer' --recursive --blob-tags='my%20tag=my%20tag%20value&my%20second%20tag=my%20second%20tag%20value'
Upload directory contents
azcopy copy 'C:\myDirectory\*' 'https://mystorageaccount.blob.core.windows.net/mycontainer/myBlobDirectory' --blob-tags='my%20tag=my%20tag%20value&my%20second%20tag=my%20second%20tag%20value'
Note
If you specify a directory for the source, all the blobs that are copied to the destination will have the same tags that you specify in the command.
Upload with optional flags
You can tweak your upload operation by using optional flags. Here's a few examples.
| Scenario | Flag |
|---|---|
| Upload files as Append Blobs or Page Blobs. | --blob-type=[BlockBlob|PageBlob|AppendBlob] |
| Upload to a specific access tier (such as the archive tier). | --block-blob-tier=[None|Hot|Cool|Archive] |
For a complete list, see options.
