# Workspaces & files
> Persist files across V4 runs and conversations.
A **workspace** is a persistent filesystem shared by runs—even runs in
different sessions. Use it for inputs, scripts, and generated files.
## Upload and attach a file
```python Python theme={null}
from browser_use_sdk.v4 import BrowserUse
client = BrowserUse()
workspace = client.workspaces.create(name="research")
uploaded = client.workspaces.upload(workspace.id, "people.csv")
run = client.runs.create(
"Find everyone in the CSV who works at Google",
workspace_id=workspace.id,
attached_file_ids=[uploaded[0].id],
)
```
```typescript TypeScript theme={null}
import { BrowserUse } from "browser-use-sdk/v4";
const client = new BrowserUse();
const workspace = await client.workspaces.create({
name: "research",
});
const uploaded = await client.workspaces.upload(
workspace.id,
"people.csv",
);
const run = await client.runs.create({
task: "Find everyone in the CSV who works at Google",
model: "grok-4.5",
workspaceId: workspace.id,
attachedFileIds: [uploaded[0].id],
});
```
Attachments are run-scoped. Reusing a workspace does not reattach every upload.
## Retrieve created files
Ask the agent to save its output, then list the workspace:
```python Python theme={null}
files = client.workspaces.files(
workspace.id,
include_urls=True,
)
for file in files.files:
print(file.path, file.url)
```
```typescript TypeScript theme={null}
const files = await client.workspaces.files(
workspace.id,
{ includeUrls: true },
);
for (const file of files.files) {
console.log(file.path, file.url);
}
```
Download URLs expire after 60 seconds. See the [workspace API
reference](/cloud/api-v4/workspaces/list-workspace-files) for pagination and
