Using Free Download Manager 6.14.2 in Linux Ubuntu 21.04.
The problem is if using "Paste URLs from clipboard" to create automatically download task for example more of 1000 links being all links png file.
Before begin download task a huge disk activity for several minutes is done in folder where is db.sqlite being that in end the file will be 5.2 MB or extremely big above 200 MB and at same time a huge internet access is done being in example to download 2295 png files was done first a internet access of more than 450 MB to only create empty files before begin download task and after start the download task 989 MB.

I not understand exactly what is the because to transfer huge data to only begin the download process being an big problem to metered connections.
In another time I had to delete the db.sqlite because was very big more of 380 MB for only less of 2000 files downloads.
Is a problem.

I will continue to use Free Download Manager, but I will avoid download using ""Paste URLs from clipboard" create much problem.
Thanks very much for reply.
