Having an issue using Claude Cowork to copy/paste large files
In short, I have a file that is 5GB
- Cowork Folder
- Source Folder
- 5GB File
- Source Folder
I'm telling Claude to create a Destination Folder and copy the 5GB file to the new folder to end up with something like this:
- Cowork Folder
- Source Folder
- 5GB File
- Destination Folder
- 5GB File
- Source Folder
These folders are on the same drive, so it's not copying to a new drive or anything. I tried it manually and it works. It's not instant, but it only takes a few seconds.
Trying to get Claude to do it gives errors. It's saying its attempting to use rsync but the write speed is going at ~9MB/sec so it'll take about 10 minutes. But the process stops when about 400MB of data is copied. Actual messages below. Any tips on why this copy/paste isn't working?

Let me kick off the video copy:

The temp path works fine for writes. Let me rsync the video directly to TEMP_VIDEO.mp4 — that path is clean:

The copy is running in the background on your machine (rsync's temp file .TEMP_VIDEO.mp4.dICpTg is at 400 MB and growing). It's writing at ~9 MB/s to the real Windows filesystem — the 5.3 GB will take roughly 10 minutes total. Let me monitor progress and finish up when it's done.

Let me check if the rsync copy finished yet.

The rsync was killed by the timeout at 400 MB. Let me resume it with --partial so it picks up where it left off — and run multiple back-to-back passes until it's done.

rsync starts fresh each time instead of resuming. I'll implement a resumable chunked copy in Python instead — each 45-second pass saves progress to a state file and the next call picks up where it left off.
