## OSError: \[Errno 19\] No such device when consuming files
If you experience errors such as:
```shell-session
File "/usr/local/lib/python3.7/site-packages/whoosh/codec/base.py", line 570, in open_compound_file
return CompoundStorage(dbfile, use_mmap=storage.supports_mmap)
File "/usr/local/lib/python3.7/site-packages/whoosh/filedb/compound.py", line 75, in __init__
self._source = mmap.mmap(fileno, 0, access=mmap.ACCESS_READ)
OSError: [Errno 19] No such device
During handling of the above exception, another exception occurred:
Traceback (most recent call last):

```
Paperless uses a search index to provide better and faster full text
searching. This search index is stored inside the `data` folder. The
search index uses memory-mapped files (mmap). The above error indicates
that paperless was unable to create and open these files.
This happens when you're trying to store the data directory on certain
file systems (mostly network shares) that don't support memory-mapped
files.
