Hello everyone,
I work on a lot of video and photo files on my 500GB NAS.
Although I defragment my computer regularly, I recently noticed that data transfer rates to my NAS are slow.
It is very important to me that my home office is intact. My data are "sacred" to me and I don't want to risk any mistakes. I decided to defragment my NAS.
Unfortunately, normal defragmenters don't work because I have very little free space 1-8%
Does anyone know of a program that I can use in such an environment?
thanks in advance
defrag doesn't work because I have 1-8% free space

First of all, the following: Extract from O&O Defrag
How much free space is required for defragmentation?Free disk space is a very important factor for a successful defragmentation. The less of it is available, the longer the defragmentation will take. This applies to all methods. It is recommended to provide at least 5% free space on the drive to be defragmented. However, this number depends on the individual system configuration and the number of files and their size. With NTFS drives, it is particularly important to pay attention to the real free space. You can do this in the drive information dialog under Free without res. Read the MFT. Only this much memory is available for user applications, which include O&O Defrag. Windows itself can also write in the MFT area. Other applications are not allowed to do this for security reasons. This is also the reason why Windows Explorer shows more free memory than is actually available for defragmentation.
What you (To attempt) can deframent with the program O&O Defrag (Shareware 30-day trial period). Program 12 will probably run until it's finished, but it could do it. If it doesn't work, then I recommend a 2 hard drive to which you transfer 50 Gb. I am very satisfied with the program once activated and it always runs in the background, the hard drives are always tidy. -
or switch off the SWAP file (swap file) for a short time. Certainly brings some GB, at short notice.
Also run a CCleaner over it to get rid of all the rubbish.
The best advice is, in my opinion, to install another FP, an external one is also ok. Doesn't cost much today. . . .

First of all, ...
Defragmenting means disk stress!
When the disk is almost full and the data is dear and expensive, a full backup should be made first.
defrag.exe offers options to check whether it is necessary at all and a defragmentation can be forced even if the memory is low.
Win and R keys and enter
cmd.
Then
defrag c: -a -v
enter and enter.It is also possible to write the resulting screen output to a file.
Only one
> something.txt
append.So
defrag c: -a -v> defrag-26.11.08.txt enter and thennotepad defrag-26.11.08.txt
to see the result.The real values are displayed, which cannot be seen via the explorer properties.
The switch defrag c: -f is necessary for the enforcement in case of insufficient storage space, but should - if at all - already be used when the system is started - via a "planned task".
So the command option would be ...
defrag LW: -f -a> defrag-report-date.txt
where for L.W.: the NAS would have to be entered.
O&O Defrag is a special tool that is highly recommended. Should you buy yourself, especially if important dates depend on it.
So much for defragmentation.The last message, whether or not it is necessary to defragment, should, in my opinion, be taken into account. See opening sentence.
But it is much more important chkdsk.
The integrity of the data is the be-all and end-all. It is therefore more important chkdsk from time to time to run as defrag.
There is also a not uninteresting forum post:
Finally, it should be noted that this is only my own opinion, as well as:
If a hard drive is almost (brim) full, a new one should be purchased and / or (always important) a backup should be made.
FPs with full margins can develop into data graves, even if they have only been in use for a short time. -
So you overlooked something very important !!
It's about a NAS, i.e. a network hard drive with its own small operating system. It doesn't help at all to use a "normal" defrag program on a networked computer, since such a program needs direct access to the FP. (or can O&O do that?)
The problem with this is simply put, that the NAS board specifies and manages the file system and not the computer on which the defrag program is installed. (At least as long as you are also connected to the disk via the LAN port)
Actually, the NAS should have such a function built into the web configuration (just like for formatting). Otherwise, only the NAS via USB (if available) can be connected or expanded and defragmented in a PC. Whereby connecting via USB does not work with every NAS.
