DeleteFromBlobStorage

Deletes a file from Azure Blob Storage for the current tenant.

Syntax

DeleteFromBlobStorage(path, fileName)

Parameters

• path (string): Path within the container (e.g., "exports/old")
• fileName (string): Name of the file to delete (e.g., "legacy.xlsx")

Returns

• boolean: true if deleted, false if not found or on error

Description

Permanently deletes a file from the tenant’s blob storage. The operation is idempotent - deleting a non-existent file returns false without error.

Examples

Basic Delete

var deleted = DeleteFromBlobStorage("exports/old", "legacy.xlsx")

if deleted then
    Log("Information", "File deleted successfully")
else
    Log("Information", "File not found or could not be deleted")
end

Delete After Processing

# Process an import file
var content = ReadFromBlobStorage("imports", "data.json")

if content != null then
    var jsonString = BytesToString(content)
    var data = ParseJson(jsonString)

    # Process the data...
    foreach record in data do
        # Import logic...
    end

    # Delete the import file after successful processing
    DeleteFromBlobStorage("imports", "data.json")
    Log("Information", "Import file processed and deleted")
end

Cleanup Old Files

# Delete files older than 30 days
var files = ListBlobStorage("exports", "*")
var now = Now()
var deletedCount = 0

foreach file in files do
    var fileDate = ParseDate(file.lastModified)
    var ageHours = (now - fileDate) / 3600000  # ms to hours

    if ageHours > 720 then  # 30 days
        var deleted = DeleteFromBlobStorage("exports", file.name)
        if deleted then
            deletedCount = deletedCount + 1
            Log("Information", "Deleted old file: " + file.name)
        end
    end
end

Log("Information", "Cleanup complete. Deleted " + deletedCount + " files")

Move File (Copy + Delete)

# Move file from one path to another
var content = ReadFromBlobStorage("exports", "report.xlsx")

if content != null then
    var success = WriteToBlobStorage("archive/2024", "report.xlsx", content)

    if success then
        DeleteFromBlobStorage("exports", "report.xlsx")
        Log("Information", "File moved to archive")
    end
end

Delete with Confirmation

# Check if file exists before attempting delete
if BlobStorageExists("temp", "upload.xlsx") then
    var deleted = DeleteFromBlobStorage("temp", "upload.xlsx")
    if deleted then
        Log("Information", "Temporary file cleaned up")
    end
else
    Log("Information", "No temporary file to clean up")
end

Notes

• Deletion is permanent - there is no recycle bin or undo
• Returns false for non-existent files (does not throw error)
• Blob storage must be enabled for the tenant (see IsBlobStorageEnabled)
• Consider archiving important files before deletion
